Buying Torque Thrust IIs, Need some info

**juiced99ws6** · 05-09-2008, 07:51 PM

Hey, I am sorry I tried a couple searches and really couldnt find the setup that I am doing and I dont have much internet time being deployed but here is the question.

I am buying Torque Thrust IIs and want 17x11s in the back and 16x8s up front. I need to know what offset and backspacing that I need for each of the sizes. I am having my dad call to order them for me and I guess that is what they asked him so I need to email him back ASAP so I can get them before I come home on vacation. Thanks in advance guys.

Be careful, not sure you can mix wheel sizes and not have abs problems (CEL)

But anyway mine are :
17x9.5 American Racing part# 50579563 with an offset of 7.00". (p/n for polished alum)
17x11 American Racing part#50571163 with an offset of 7.75". (p/n for polished alum)
315's rear, no issues what so ever with rubbing, but if you jack up the car via the frame and let the rear wheels/axle hang down, the inside of the tires may hit the jounce pads? (its that close-but slp jounce pads are different than oem gm!)

Spend some quality time and read thur this entire article/thread, your question will be answered but be patient, its a long, long read.

By chance, are these the one's offered by Hawkthirdgenparts.com? I was looking into this setup myself for my 2002 SS.

I thought 17" wheels were the smallest that would fit around the brake rotors/calipers on these f-bodies?

I havent had ABS for like 3 years since I got the wrong 12 bolt sent to me without provisions for ABS and I just didnt want the hassle of removing it and sending it back sothe different sizes will not pose a problem for me. Thanks for the information, I really appreciate it.

Camarofan, The stock wheels for base Trans Ams and Z28s are a 16 inch rim. 15s will also fit but require you to shave the caliper.

If your asking me if I got mine @ hawks, NO.

I bought a set of 6 rims off ebay ($931 shipped NEW)...4x9.5 & 2x11, he had 9.5 all the way around and the 11 were for slicks.

If your asking if mine are the same as the ones hawks is selling, I would say well kinda of, theirs maybe the same p/n except that mine were bought polished and then sent off to a chrome plating shop to be dipped.
