68 camaro front wheel size

[trevor572]

Hi, new here and just wanted to ask, I have a 68 camaro and in the process of changing the control arms and installing coilovers on the front, I am going to change to a 17x8 wheel and would like to lower the car as much as is practical, should I stick with a wheel with zero offset or go with an offset that moves the wheel inboard to avoid contact with the guard lip and wheelhouse? Thank you.

whose's control arms and coil-overs? do they have a wheel offset recommendation? if you move the wheel offset inboard will it hit your steering arms? what brake company are you using and what is the offset of the rotor?

Hi Rod, i posted question on my lunch break, so sorry about the lack of detail. As far as i know as the car sits now the suspension is stock with the exception of a 13 inch CPP brake kit, 18x8 wheels with 0 offset and 225 tires. I am fitting Speedtech control arms, Viking coilovers that use the stock top mountings and a Unisteer rack and pinnion. The wheels i like come in 8, 9 1/2 and 11 inches, I had read a 9 inch wheel with 5 1/2 back space was the maximum that would fit, that why I was leaning toward an 8 inch wheel although i will use an 11 inch on the rear, I have just finished installing DSE tubs, I had read that the big difference in wheel sizes was less than ideal. Thats about all the information I can give you right now. Thank you, trevor ☺

In theory, a +6mm offset will center the wheel in the wheel well. A 0 offset will push it out by 1/4", which may or may not be ideal. I rub the front subframe with a 245/40/18 and +6mm offset on an 18x8. Luckily the SpeedTech LCA's have built in steering stops. If I ran a +0 up front, I don't think I'd rub on the front fender, and I'd get a little more turning radius back. Every 1st gen is different though.

With your 225's you should be fine with a +0 offset.

you can run the tru turn with the speedtech arms and that will let you run that 9.5 rim with 5.5 backspace in the front....looks like my car then

How does the tru turn allow the wider rim? On mine, it looks like the limitation is the inside tire to the frame at full lock.

Hi Rod, I didn't know what tru track was, I have found it on ridetech's website and read about it, one last question, are the front fenders and wheelhouse on your car stock? Cheers, trevor

I wonder how true that would be for a 68-74 Nova.....same sub-frame, obviously different fenders. That is my plan....sorry to hijack the thread!

Hi. I found tru turn on the ridetech website, they have information there and for the camaro they mentioned maximum wheel size, i dont know if there is any info about nova's but it might be worth a look. Cheers

Every car is different..You might have to cut or massage your fenders to avoid rubbing at your desired ride height.. The biggest benefit of tru turn is being able to run a much wider wheel tire/combo. Instead of a 235/245 up front you could fit a 275, which would match your wider rear set up better

trevor572, I've checked out the TruTurn on their site a lot. I knew it allowed for a 10" wide wheel up front.....I was basically thinking out loud about the backspacing Rod mentioned and wondered how true it was for a Nova since they share the same sub-frame and suspension....next thing I know, my finger clicked the mouse and I hijacked your thread! I
did notice that the ridetech site specs a 5.75" backspacing (for Camaro AND Nova) which is a 1/4" different than Rod suggested. I'm not doubting his specs (he as well as his car are much more capable than me or mine will ever be, plus he works there), but it does seem like one of those situations where it is best to measure your own vehicle (not that you weren't going to) instead of going solely by what we all read.......and once again I have hijacked your thread! My apologies!
