wheels are too tight!!

**cancam99ss** · 06-18-2010, 09:01 PM

I just bought a pair of z06 aftermarket wheels and they wont go in because the stock lca are in the way i have a 99 ss m6 i am guessing i need spacers which was do i need though?

My Z06 wheels fit fine. They measure 17x9.5 with 275-40-17 tires

With the wheel off the car, lay a straight edge across the rotor hat and measure from the face of the hat to the LCA. Next, lay the wheel face down (on a towel preferably) and lay a straight edge across the rim or tire. Measure from there to the back of the wheel where the lugs go.

The difference between the two is your clearance (or lack of clearance in this case). You then need at least that much to clear the LCA, plus an extra amount added for comfort. The sidewall on low profile tires doesn't roll much, but you have to remember that your rear moves in an arc as it pivots on the panhard bar. Therefore, as the suspension goes up and down, the tires alternately move closer and further to the inside of the wheel house.

I would think that you would want at least an inch of clearance, but that is a pretty thick spacer. Hard to tell without actually seeing it. Better to have wheels that fits versus a dangerous mount setup imo. They do make spacers with studs. You bolt the spacer to your wheel and your wheel to the spacer, but I have no experience with these.

okay i am thinking about an inch if not an inchand a half ! reccomend any good places to find these spacers

**pajeff02** · 06-20-2010, 10:24 AM

Question: Is it about the same on both sides with the suspension loaded?

You can find spacers at most parts stores and on-line at Jegs and Summit, if I recall. You'll have to be careful though as the tire may protrude from the wheel well and look funny.

what do u mean protrude bud

**pajeff02** · 06-20-2010, 12:11 PM

Stick out from the side of the car.

when you figure out what size spacer you need cut out a couple wood blocks that are the right depth and tape them to the wheel studs. with the car on Jack stands (preferably under the axle) put the wheels on and lightly tourque. then you can see how much they will stick out before you go and buy the spacers.. just a suggestion

Did you mount tires to them already? If not call up whoever you got them from. Talk to them about your problem. Maybe they can switch them out for a pair that fits correctly.

Don't know if these will help but its another option.

now that you have the offset bushings the only thing in your way is the inner fender so go git yerself a big fuckin hammer and show that inner fender some tough love

**tatertot91** · 06-27-2010, 10:28 AM

Is your car lowered? Did it only hit on one side? I would look into an adjustable panhard bar as well if so
and if you end up running spacers look into longer hardened wheel studs

But is it hitting on one side or both? ether way if you're lowered and are running wider tires, do yourself a favor and get an adjustable panhard bar

You gotta center that rear end because once you lower the car it pushes the rear end over and out of alignment.

**cancam99ss** · 07-07-2010, 04:46 AM

spacer. lowercontrol arms and adjustable panhard going on the car on friday

**xmarkx** · 07-07-2010, 07:45 PM

just incase anyone didn't know umi also sells offset bushings by themselves so if your somone who already has rod end lca's (like me) you can swap out the bushings pretty easy. I think they're like 40 bucks

**cancam99ss** · 07-07-2010, 08:23 PM

i actually have lca's but bushings dont match i bought umi but they are too thick
