How to make 315's fit your Camaro/Trans-Am with no rubbing

The simple modifications required here take very little time and insure that you won't suffer tire damage/rubbing issues with your new 315's. Some people may never experience rubbing with 315's or say that some brands run smaller than others (Nitto 555's ect). I say just spend the 30 minutes and do it right.

Tools required:
-BFH (Big Fing Hammer)
-5" Angle Grinder (picture below)/ Safety Goggles
-Rubberized Undercoating
-Jackstand

OPTIONAL- Adjustable Panhard Bar. You will need this if you notice you need to recenter your rear. I recommend getting one anyways.

PLEASE NOTE

If you are lowered:
-Fender rolling may/will be required
-Adjustable Panhard Bar is NOT optional
-Alot of BFH will be required

I believe the Trans-Am has slightly more room in the wheel well than the Camaro, but I recommend taking these precautions anyways.

315 series tires DO NOT fit 9" or 9.5" wheels.

REAR Only

10.0" ... +38 to +54 mm .... 275, 285, 295
10.5" ... +38 to +50 mm .... 285, 295, 305, 315
11.0" ... +45 to +56 mm .... 305, 315, 335

Some have used the +38 offsets with an 11" wheel but it does stick outside the fender and is definitly not recommended on lowered vehicles. +50 and +56 are the two most common. +50 is the better fit (for the ZR-1 replica).

Let me know if I missed anything

Excellent job! I had to do all of this but did not take pics of the install. :thumbup:

very good show ! I recommend sticky!

Great job, i like how you pay attention to detail and did the finish work

Thanks for the comments, if anyone is doing this and something is unclear please pm me or post here.

oh shizz!!! i gota go change my panties now!!!!



NICE FING JOB!!!!!

looks good wished i could get 315's on my gto

well, this is awesome because i am wanting to put some on some zr1's.
Sorry to just jump on this thread, but i have a question.

What would be the best tires to run for grip on the road but also be able to push in the turns for th 17x11's??
I am looking at pushing around six to the wheel and more if i need to kill a pest on the go.

I know that Eugenio_SS (a mod here) is running the new Nitto Tires on the street hopefully he will chime in here.

If not PM and ask him how he likes them zero...

What Brand Are Gs-d3's?

Goodyear Eagle F1 GS D3

awesome job first of all, i was wondering , i just purchased some speedlines for my formula and i wanted to run some 315's out the rear, who makes the cheapest 315's?

Not sure, I know Sumitomo's are cheap

Yep had a set of Sumitomo's shipped to my door for $420. 275's up front 315's out back. I cant complain about the price and it got my ZR1's on the Z. No more snowflakes :nana:

so i heard you cant run 315's on 9 inch rims, i mean can you or cant you? if i grind down the bump stop and use a big fricken hammer will they work, or do the tire just not fit the rim?

Not advised

rear only makes me laugh... there is more room in the front that in the rear, even w/ turning into account... :lmao:

:itsok:I have seen it done with the use of spacers, longer studs and some grinding.

I disagree that there is more room, and I wouldn't run larger that 10" on 285's on the front without those mods.

Honestly longer studs are needed from the factory as there is just not enough threads on a stock stud (see pic):

http://i32.photobucket.com/albums/d3...atInstal83.jpg

This is a good thread! I recommend stickey as well!

Sumitumo's are like 109 at Tirerack and are definately the cheapest. I have them on my ZR1's however for some reason they don't look near as wide on my car as those on his. Good post I had to learn the hard way about all of that especially the part about the lowered car went through 2 tires before I fixed it.

I just ordered 2 315 Sumitumo's from TireRack and after shipping it was 225. Cant wait to put them on!

So is cutting and rolling the rear fender lips only required if the car is lowered? Does anyone have a "how to" on rolling the fenders?

will the 315's fit on the my rear C5 Z06 rims? i had to hammer alittle to get the 295's in there. thanks

I have 315/35/17 Nitto DR's with no issues, they never rubbed .......the BFG 315's DR's rubbed!

Is anybody running 17x11 wheels with the 315 tires on a '97 or earlier f-body convertible? I'm running into some contraditory information regarding fitment of this set up on LT1 year convertibles.

plenty of LT1s w/ 315s can be found in www.frrax.com
They fit as easily in LT1 4th-gen than LS1 4th-gen... plenty of reading in perspective.... search will be your friend.
http://www.frrax.com/rrforum/index.p...=6134&hl=17x11

if you want 17x12 on all 4 corners, it works well as well:
http://www.frrax.com/rrforum/index.p...=4967&hl=17x11

there is more room in the front than in the rear, btw.

Eugenio, Thanks for all the information.

Here's an excerpt from an Ebay ad from AFS for the ZR1s. It says they don't fit the 1993-1997 convertibles, but maybe they mean they don't without ANY modification (hammering, lip rolling)?

"AFS Corvette Wheels ZR-1 style 17 x11 Camaro Black

ITEM DESCRIPTION: This is a combination set of four new BLACK replica ZR-1 style rims with center caps. Please note these are not blemished wheels. This set has the new wider outer lip cut, giving them an updated look. There is NO RESERVE on this auction. Please see the pictures below.

WHAT THEY WILL FIT: They will fit '88 through '96 Corvette. They will also fit 1993 through 2003 Camaro/Firebird or Trans Am. They will not fit the '93-'97 Camaro, Firebird or TransAm 'Convertible'.

SIZE AND SPECIFICATIONS: There are two 17" x 9.5" (+56mm offset with 7.4" backspacing) rims for the front and two 17" x 11" (+50mm offset/7.93" backspacing) for the rear. These are the same as the Grand Sport offsets. The lug pattern is 5x120.65mm."

I addition to the information in this Ad, Tomz Wheelz would not give me a definite confirmation that the 11s (+50) would fit my car either.

Hopefully, you can understand my lack of clarity on this issue?

they say the same thing about LS1s... and it's BS.
Heck, GM even did not make the 17s available in 1998 on the convertibles... the SS had 16x8 ZR1 wheels.
It will fit.

I have a lowered 2000 Formula. I'm putting 17x11 315/35 in the rear. Will I have to hammer the fender well and grind the bump stop as well?

Blackwidow99... I have a 2002 WS6 with stock suspension and I am considering Torq Thrust Ms in the rear 17x10.5 (44mm offset) with 315-35-17s (possibly BFG KDWs). Do you think I would be able to fit them without hammering the wheel wheel or grinding the bumpstop? I would like to avoid doing that if possible. Thanks!

The bump stop is actually called a Jounce Bumper

The bump stop sits atop of the spring

I got the two names confused. Thanks for the clarification. Still, will I need to make any modifications for the wheel setup I mentioned earlier?

Shoot man you could probably get away with it.

Keep in mind, you might get them on and have no issue, but it's going to get alot closer while turning or with groceries in the car. Go on a test run after you get them on with some moderate speed turns. Listen for squeaking and check for rubber in the wheel well when your done.

I recommend the safe route. The mods literally take 20-30 minutes, and could save you a pair of tires.

I will definitely keep that all in mind. Thank you for the information!

FYI, you CAN run 315's on a 9.5 wheel!! I think they look great!! And it does not rub at all!!

Yeah, and it looks like a balloon and wears the tire out in the middle. Maybe on some classic muscle but not on a Late Model

Everyone ignore this post.

Is there such thing has having too much grip? I mean i'm stock right now but of course I wont be forever. I have traction problems now(Kumho Ecastas) and was just wondering after how much power should you really upgrade to the bigger tires? I don't see a point to upgrading to a 275 then do a few more mods and then upgrade to a 315. So when should you upgrade to 315's?

Too much grip? No such thing.

315's are fine for a stock car, there's no need to wait until you hit a certain point with your mods. Kumho Ecsta's are pretty cheap tires, but you may want to consider some suspension mods to keep those tires planted.

If you really want grip and aren't too worried about tread life or inclement weather performance, upgrade to some DR's. You can shave plenty of time off your 1/4 by putting DR's on a stock car. If you're going that route, set aside some $ for a new 12 bolt/9 inch.

I have Kumho Ecsta's also, 275/40/ZR17

When my Camaro was stock, I would take off from a dead stop or a roll and smoke the tires. It was tough to get a good start on the street when running another car.

Now I am modded with 400 HP and 4:10s and I can not take off at all with out worrying about hitting the rev limiter. Wider tires & wheels, IMO, would definnitly help and Drag Radials are not an option because of $funds$ and the miles that I put on my car.

I am curious, do the Kumho Ecsta Supras were out in the center first for you also? I have tried lowering the pressure and I can't prevent it?

My 275/40/ZR17 Kumho's are on 17x9.5 ZR-1's

Black widow, dude people should ignore you for that stupid remark you posted!! After mounting my 315's, many 4th. gens are running them:especially at the track!! And they dont bubble bad all. I will email you pictures so you can judge them for yourself, they DONT look bad!! Now, is there such a place called Atlanta, Gawga??

:itsok:

The 4th gens with 315's you see at the track have 10.5" or 11" wheels.

Read the tire manufacturers recommendations.

If you are foolish enough to try it fine . . .

If you find a tire shop ignorant enough to install them fine . . .

But encouraging others to recklessly experiment, NO.

:slap:

Thanks for the info

Im NOT encouraging anyone to do anything!! Im just telling anyone that you CAN run 315's on 9.5 wheels and they look good!! You want to talk UNSAFE, fine!! You probably dont have drag radials on you Camaro 'cause it aint that quick anyways!!:however, how many of us utilize the suggested air pressure (cold/hot) when we go to the track? Bet we ALL run well under that rating!! Heck, even NASCAR breaks those rules; some to the extreme even! So keep your self-rightous, over-analyzing comments at bay and reserve your incompetence of stupidity and ignorance to yourself!! Have a nice day!!!

:hifinger:

I saw 315s mounted on 9" wheels with no isues. The guy has been running them for over a year and they look fine. Not worn in the middle or unevenly either.

atop the spring is the spring isolator.
the bumpstops and jounce spacer are together... the jounce spacer comes on the SS, and it should simply be removed for added suspension travel.

still unsafe... seen 315s get unmounted while pushing the car on a turn... wasn't nice.
Also, you'll have better grip on well mounted tires than going the redneck approach and installing tires that are plainly too wide for the rim. You get better results w/ 275s on 9.5" wheel than you'll get cornering w/ a 315 on a 9.5"
get 2 sets of wheels and try it.
it's another choice between redneck bling vs safe/efficient performance.

Thanks man, but I want your car. Black is the color to have especially w/ your wheels!

Listen fellas, just because you can squeeze your tire onto the wheel and drive down the street doesn't mean it's safe.

http://i188.photobucket.com/albums/z...fatties5lr.jpg

I recommend everyone go ahead and ask their wheel or tire manufacturer in advance if you are considering running anything less than a 10.5" wheel with any 315+ tire.

I will gaurantee the 315s on 9" wheels I saw looked nothing like that^. They didnt buldge out at all. The guy has ran em like that for a couple years-no problems. If they didnt come off his rim I doubt they are comin off anyones-BUT-I would prolly go with a wider rim myself.

Discount Tire has recommended the wheels and tires for me... :thumbup:

^ haha Yeah mine too! LOL

That sucks, so you aren't able to work on or maintain it yourself?

No I cant work on my car. I am lucky though because I finally(after a year) found a great mechanic who specializes in Fbodies and has really fair prices. The first couple of shops were totally trying to rob me because they thought I didnt know about cars because I was taking it there for simple things. I have always worked on my cars till this happened to me. Just really happy I found a good guy to deal with which is hard these days.

** The guy who runs the shop will do stuff like-he put on my billit grill for free when I took my car in last time.

Brand of tire matters too.

Look at my new Goodyear 315's compared to my old Bridgestones. Bridgestones were mounted on 9.5 and Goodyears are going on 10.5 (I had the wheels widened 1")

http://www.cdntechnologies.com/camar...idgestone.html

And just for fun compard to 11.5 x 16 ET Streets:

http://www.cdntechnologies.com/camar...1.50-16LT.html

Here is being bad with 315 on a 9.5" rim:

Great write up I've had 315's for awhile and I still need the bumpstop mod. Tired of jacking the car up from the rear axle. Some ass at discount bent the bottom of my dif cover it looks like.

I found a guy to widen my stock LE rims.
I want it to look like this:

http://www.lalim.net/02SS-LE/wide.jpg

but stock looks like this:

http://www.lalim.net/02SS-LE/stock.jpg

Note: neither pictures are of my car.

The company I found will add 2" to the inside of the rim, but that wouldn't push the outside lip of the rim outwards.

My question is: How do I get a different offset on the stock rim? Is there a spacer that can be used? If there is such thing as a spacer, are they safe?

BTW: $200 each to modify the stock rim to add up to 3" of width. I want to take the 17x9 to 17x10.5 or 17x11.

If I only go 10.5" wide, will I have to grind the bumpstop, etc, when using a 315 tire?

Thanks for the help!

The company I found will add 2" to the inside of the rim, but that wouldn't push the outside lip of the rim outwards.

My question is: How do I get a different offset on the stock rim? Is there a spacer that can be used? If there is such thing as a spacer, are they safe?

BTW: $200 each to modify the stock rim to add up to 3" of width. I want to take the 17x9 to 17x10.5 or 17x11.

If I only go 10.5" wide, will I have to grind the bumpstop, etc, when using a 315 tire?

Thanks for the help!

I had www.weldcraftwheels.com do mine they turned out fantastic.

You will need spacers from www.skulte.com if you want to push the wheels back out. They are perfectly safe.

My wheels needed no spacers I took 17x9.5 to 17x10.5 by adding 1" to the back, which increased backspace from 7.1" to 8.1" and a hammer to the inside wheel well made them fit. I wanted the tucked in look so that suited me just fine, meaning the outside lip is exactly where it was stock and all my extra 315 tire was added to inside.

Those guys can add to the outside too if you want! It just costs more $$.

Good luck post pics when you are done!

Good luck

Yes, I've been talking to weldcraftwheels.
I don't mind the spacers, but I don't want to pound or cut anything. I want the lip to be like the top picture. I can get a 315 BFG onto a 10.5" rim. I can't add to the outside of the rim, because as you see in the pictures, the stock rim doesn't allow that (Weldcraftwheels says).

Maybe a 305 on a 10.5" rim won't rub???

I'm not sure

What is the backspace now of the stock rim? Take a straight edge and lie it across the very back edge of the wheel and measure down in inches to the mating surface and I can help you figure it out. Mine started at 7.1 and ended up at 8.1 - I could have added more to get a 'real' 11" rim but I did not want to use a 1/2" spacer. Just pure laziness in having to deal with spacers, I have nothing against them and have used them in the past.

Just put a spacer on it if all you want is for the rim to be closer to the lip.

If I put 305/35/17 goodyears f1s on 17 X11 do you think any mods will be necessary? I really dont want to start beating on my car but at the same time, I want wide ass tires on there. Anyone have this set up or know if there will be rubbage?

You might wear out the centers with to small of a tire.

there is that much of a difference from a 305 to 315?

I think 305's on a 10.5 inch wide rim would be better than putting 305's on a 11 inch wide rim. 315's are perfect for a 11 inch wheel. Any smaller and it might wear the centeer out.

:lol:
on a 17x11, you will have from 275/40-17 to 315/35-17 PROPERLY mounted on the wheel.

not true... you can put a 275 on a 11" wide rim and not do that..

i'd widen it 2" and put a 1" adapter from www.skulte.com

what exactly do you mean? and what adapter do I need? or just the spacer? Thanks!

i mean widen the wheel by 2", making it a 17x11 instead of a 17x9
due to the widening, the new offset will be ~+24 to +25mm offset... Adding a 1" spacer or adapter will make the wheel equivalent to a 17x11 +50mm offset.
adapter is a spacer but due to its thickness, has his own studs.
