Question Torq Thrust II Wheel sizes for 68 Camaro?

Hey guys,

Im planning on getting a set of the 17" inch American Racing Torq-Thust II wheels for my 68 camaro...

What I'm wondering is for a 67-69 body camaro, what is the proper wheel size, width and backspacing for both the front and the back???

Also, what size tire would be the ones to get for those wheels front and back also to fit good???

I dont want to order a set and then they dont fit correctly.

Thanks.

Re: Torq Thrust II Wheel sizes for 68 Camaro?

I just got done putting a set of these wheels & tires on my 68 RS/SS. The sizes are as follows:
Front - 17"x7" w/5.5" back space, tire size P215/50ZR17
Rear - 17"x9.5" w/5.5" back space, tire size P275/40ZR17
Lug pattern for both wheels - 5 bolt on 4.75"
These fit my car perfectly and I have not have any problem with tire rub in the front or rear.

Re: Torq Thrust II Wheel sizes for 68 Camaro?

that's a lot of backspacing for the front. I usually do a 17 X 8" with 4.75" - 5" b.s. on the front, and a 245/45 tire. Depends on ride height, can be fairly low with the above combo, but not slammed.

This is what you want for the front

Front: 17x8 (4.75" backspacing) - 5x4.75 pattern (American Racing 505-7863)

Works with stock or lowered suspension

Re: Torq Thrust II Wheel sizes for 68 Camaro?

on all of my 1st gens, I went with:

8" wide fronts, 4.75 to 5.00 backspace (5.00 tucks in better)
10" wide rears, 5.50 backspace (can also use 9.5" wide with same backspace)
245 wide front tires
275 wide rear tires, or 285 wide with rolled fender lips

Re: Torq Thrust II Wheel sizes for 68 Camaro?

Thanks for all the help everyone. Since it seems as though alot of you have different opinions on what works and what doesent...Do any of you have photos with the size combo you are suggesting on your camaro so I can see how they look?

Thanks guys

I will take a few pictures tonight and send them to you. Yes,I am at stock height. I did make a mistake on the back spacing on the fronts. They are 5.0" instead of the 5.5". I know there are a lot of opinions about sizes but mine are on the car and working so you decide who's right!
Could you please send me your e-mail address, so I can forward you the pic's? Here's mine: lindsmar@comcast.net

Re: Torq Thrust II Wheel sizes for 68 Camaro?

I'm about to purchase the same combo for my 67. I thought the best combo from searching on here was front 235/45/17 (17X8 w/4.75bs) and rear 255/40/17 (17x8 w/4.75bs). I've also read 17x9.5 w/5.5bs for the rear, does this fit better? PLEASE let me know if I'm mistaken. Sorry, not trying to hi-jack, hopefully will help us both out.

Re: Torq Thrust II Wheel sizes for 68 Camaro?

I'm in the same boat, I"m ready to order and I'm comparing to the TT chrome versions (beleive the are called TT M. They are backordered so they are hard to find. I'm not sure what backspace options they have (they say 0 offset... and not sure what that means in terms of backspace but I think it's simple 4" backspace) and am worried which might force me to just order the TT2's. So if the backspace is really 4" on the M's and not 4.75 like the TT2's, doesn't that mean the M's will stick out more and will that look ok?

Why would you put 255/40 on the back on the same size rim?

Re: Torq Thrust II Wheel sizes for 68 Camaro?

255's are wider. I looked up 17X9.5 and the only backspacing is 6.5 and 7". This isn't too much backspace???

I just found out that a 0 offset on a 8" rim is 4.5" backspace, so i guess if 4.75 works on the TT2's then TTM's should be ok, right?
