18 Vs 17 Inch rims? - Lateral-g Forums

WicKeD_SS · #1 11-23-2006, 02:22 PM

Hey guys I noticed that almost all the 69 camaro's on the site have 18 inch rims and about 90% of the 67 and 68 camaros have 17 on the front and 18 on the back. Is there a reason why?

I am wanting to order rims very soon and I didnt know if 18 inch rims will not fit on the front. I have a stock sub-frame and stock upper and lower control arms. Im looking at going with 8 inch wide on the front and 12 inch wide on the back.

What rims would the pop of lat-g order if you where in my shoes.

Thank you for your time guys!

18x8's will work on the front with no problem . But you say 12" on the back ? I take it you are doing a mini tub?

Well I just ordered 17 x 8 frt and 18 X 9 rear. I hope they fit OK. 12" seems pretty wide your car must have tubs or mini tubs for right?

10's on the rear are the biggest a stock 67-68 f body will take and the bs has to be dead nut.

Bigger isnt always better, unless it has a presumed function or when your trying to make up for something else.

In reality, the 69's rear section can naturally fit larger stock without modification. But then again, there is a certain direction with a certain crowd that has to play 'keep up with the Jones'. Well that, and DSE wont build anyother year 1st Gen.

Not to knock the combination, but it would be in your best interest to keep the front to rear rim width, within an inch to an inch and a half front to rear.

However good it looks (or not), having a rear rim and tire width that different will cause a rather noticable increase in understeer... which is hard to dial out without running some really aggressive alignment settings. So aggressive, that it changes predictability in steering and kills tire wear.

For the front on a stock front clip, you can fit an 8" with ease... and a 9.5" with some backspace attention. For the rear, a 9.5" is pretty much a slam dunk and a 10" could fit with careful attention to shock placement and forward inner fenderwell clearence.

An 18 x 9.5" on all four corners would be my choice.

The combo that is a sure fit on first gen camaros is 8's on the front w/ 5" b.s. and 9.5's on the rear w/ 5.5" b.s.

17" wheels allow for more side wall which gives you a little better ride than the 18s with the same tire diam. With that said I prefer the 18s.

A 9.5" wheel on a stock s/f and won't have tire rub at full lock...have to see that to beleive it! I'm not saying it isn't possible, but my experiances are doubting it.....my new front wheels are 18x9 with a 245 tire and it's a tight fit, both to the frame and fender...what car is running this?

#1. Key point..... adjustable 'steering stops'.
#2. Key point..... the right steering box.

I know of a few 67-68's that run a 9.5" with a 275 and dont have the associated problems when the key points are adhered to. I am assured that an 18 x 9.5" will work without problem.....

FWIW, Stielow's Camaro X is utilizing an 18 x 9" with 6.125" BS, without issue.

Thanks for the info! So what you are saying is you can't do it in 'stock' form, you have to adjust the stops, which in return lessons the turning radius...this all makes since to me, I thought you had a way to keep the stock turning radius and fit the 9.5" wheel. Again thanks for clearing that up.

Yep I knew Camaro X had an 18 x 9" in the front as we both had our wheels on order with Fikse at the same time and we used his numbers as referance when building mine....
