Finally got my two new fronts mounted...still waiting on the custom offset rears.
The fronts are ttIIs w/245/45-17 bfg g-forces. These tires are MUCH more responsive than the radial t/as. A little stiffer too cause of the 45 sidewall instead of the 235/60-15s I had on there.
Wheels are upgrades from 15x7 to 17x8, and the backspace was 4.5", now 4", so these tires fill the fender much better.
Now I need to drop the front about 1" and will research how to adjust the torsion bars. Hope I have enough room to do so.

PS...I reversed the left side of the image (before and after) so you can easily see the difference in the wheels.

I feel like I'm the only guy running Staggerd 20s all around.
Anyone else running 20s on all four corners?
I have a small issue in the front wheels... On clears a turn by yhe other does not so I might need to roll a fender.

Special order offsets for the rear? Who offers these and what is the size & custom offset you're getting to make things fit? I'd really like to see pics when you lower the car, my only issue with the really low profile tires is the gap they leave filling the wheel well. 60's don't have that issue but also don't handle as well as the 45's & 55's. Great look so far!

Later, Jim

american racing torque thrust IIs are 2 piece wheels and are available in custom offsets. Mine will be 4.5" backspace to allow for the most wheel and rubber I can squeeze in back there without relocating the springs. Every car is slightly different, and some have had mods done to them without the current owner even realizing.
Ive already lowered the front another inch since the picture, and it gives me about 3.5" clearance to my header flanges underneath. Lowering an inch took 2 full turns of the torsion bar adjusters on one side, and 3 on the other to even it out, with the fender lips at 24.5" above the ground. I may even raise it a little if I can once I get the rears on there next month.

So I am sitting here during my lunch break and started day dreaming about what it would take to fit 325/50x15 rear and 275/50x15 front.
Any one have any experience or thoughts?

I know that if you go this wide in front, you may have to trim the front fender lip, at the lower part toward the bumper, or else it will rub when you turn.

I don't see it happening on the front with 15" rims. I doubt you can tuck the rims back in far enough. Mike Tyler has 275s on the front of his, but I think they are 45 series. That shorter tire probably makes the difference. You can see his setup here. http://www.cuda-challenger.com/cc/index.php?topic=42140.0

Anyone had 18x9.5" wheels with 275/40-18 at the rear?
Will 5.031 in backspacing work on a 1970 'cuda with stock suspetion?
Offset is -4.00mm

I'm going with 18x8" with 4.5" backspacing and a 245/45-18 tire at the front

I have these on mine. I'm running 6.9" of BS and offset shackles. You should be in great shape, depending how low you go. I know I've got at least 2" to the outside.

I got 17 x 8 - 4�" Backspace, - how big can I go on tires..

the_engineers · « **Reply #341 on:** January 26, 2010 - 11:09:42 AM »

Tire manufacturers have wheel width recommendations on their websites. Looking at a few, looks like 255's are about the max recommended for an 8" rim.

PlumCrazyChris · « **Reply #342 on:** January 26, 2010 - 11:52:07 AM »

Thats true Engineers, but there are lots of guys running wider tires on the street then what is rated as far as rim width with no problems. How many guys on here run 275s on an 8" rim. This may be naive, but if the tire fits on the rim, I say go for it.

If your running autocross or road racing, then you should know what you need better then us.

I would very much appreciate seeing pictures when you're done, especially after lowering the car to where you want it. The problem I've seen on some of the cars running larger rims and lower profile tires is that they don't fill up the wheel wells leaving a gap on the top and sometimes sides. I like what I see with your fronts so far and would appreciate a picture just showing the difference now after you lowered the front. On the backs, so you're staying with 8" wide rims with more negative offset in the back? Didn't know if you were trying to fit 9 / 9.5" rims in back with the additional backspacing. One last thing, how difficult was it to order the custom rears? How much extra where you charged? Looking great so far, thanks for the info.

Jim
