HamMach1

Trying to get ideas.

Looking into the following for the rear wheels/tires:

17x8", 9", or 10.5" with a 26" tall, 275 or 315 wide tire, or...
15x8" with a 26" tall, 275 wide tire.

Any of you with 17's and are successful?

Also, I have 18" wheels right now. 18x9 up front with a 265/35/18, which I guess is like a ~25tire. Could I run a 17" on the back still with a 26" tire?

So many questions

Stkjock

you need to provide more info.

what rear gear?
what RPM/MPH are you traping and in what gear?
where does your car make peak power and where do you spin the car too?

4.10
Around 5,500 I'd say (forgot exactly since it was 2 weeks ago since I was last there)/~99.59MPH in 4th gear. I either shift at 6100 or 6500 through all four gears. Still practicing to see where the Mach likes to be, especially up here in this ****ty elevation of 3700.

Here is a dyno video with the graph at the end if you want to look.

As for now I'm running the big *** FR500's you see in my sig. 305's out back and 275's up front. Once the car has a blower on it I plan to swap to GT brakes in the rear to run a 15" wheel out back and a 17" skinny up front.

As for figuring stuff out about your car, hit the the Mach 1 registry. Lots of good tech info over there.

I have a big as 18x10 dd wheel. I ran a 275/35/18 all season Pirelli's n cut a 2.17 60'. I recently bought 295/35 kdw 2's. I have yet to get to the track with em though

235/50/18 pirellis on oem gt takeoffs. 1.9x 60s

26.5/10.5/17 mt et street bias ply on 17in racestars. Only 3 passes on those with a best of 1.81 60ft.

I'd go with a 26" tire, 17 x 8/9" rim, shift at 6500-6600, just past peak power.

I would consider just going with a 275 17" MT Drag radial....honestly think it would more than hold at your power level. A 26" slick would no doubt hold better, but imo you don't need that much sidewall and your going to sacrifice some top end with the extra drag of a slick.

with your setup a dr would prolly suffice, but it'd still be holding you back from what a good slick will do. however to get the best you're gonna need a 16/15" wheel so you can get more sidewall. I had a 17x8 wheel with a 26x10.5x17 et street bias ply on my '95 and it worked good, however It was still kinda tricky getting it to hook.

Try a 275/50/15 Mickey Thompson Drag radial. 15" wheel so you have more sidewall for beter traction, and overall height of 26". When my car was making 550rwhp, I used them with pretty good success.... went a 1.64 60ft with zero suspension mods.
