Looking for a 15" rim that will fit with no modification to my 02 z28.


Car is lowered.

What 15" rims size, offset, backspacing will fit with no modifications.

Also what Size drag radial will fit, Looking to swap and drive to the track and back.

This is covered everywhere.

15x10 with 7.5" BS is the generally accepted size. I think that sticks out a little bit. I think a 7.8" or 8" BS would be better.

Tires... well depends. If you have the power and gearing to take advantage of a 28" tire, 275/60-15 or 295/55-15 would fit the 15x10 without much mod. The 325/50-15 might take some work.

If you just need a 26" tire, a 275/50-15 would fit.

I've got a set of Weld ProStars, 15x3.5 up front with 165/80-15 and 15x10 rear with 275/50-15 Nitto Drag Radial that I run around on from time to time. I run a small spacer front and rear to clear calipers but they fit nicely.





As you can see here, my car sits LOW


As mentioned it's been covered but I run a 7.5 BS rear as well, and as low as I am I can't really run a 28" tall tire. I could probably squeeze it in there but I doubt I'll try even though I really need it to take full advantage of the car.

I run racestar darkstars, 15x4 front 15x10 rear, 26x10.5x15 rears, lowered with strano springs, best 60ft so far is 1.53 on Hooiser drag radials

Well 60ft can vary GREATLY! How much power do you make? What suspension setup? auto or stick? What tires? etc etc. So chewy here pulled a 1.53, you may only pull a 1.8..... Lots of variables. As far as brand it depends on how much you want to spend and what kind of "look" you want. I like my prostars but they were free, if I had to buy some I would go with ones similar to Chewy's or the Centerline Revolution or Qualifier

This was my second time to the track with this car. 295/35/18 bfg drag radial tires at 20psi.

never put on a dyno, any guess on rwhp/tq?

420-440hp/380-400tq would be my guesses. Your mph and et's are pretty good, if you really got it dialed in I could see shaving a few tenths off. Not bad runs though for sure, my last time to the local 1/8 mile was 7.9@94 on motor, no one could hook that day. If you can squeeze a 28" tire under your car that would help but I think a good 275/50-15 (say a Mickey or Hoosier DR), everything dialed in right, I think you could pull 1.5-1.6 60's and get down to 11.50's with your setup, possibly more depending on track conditions

ok getting the weld rt-s 15/10 with 275/50-15 mt drag radials.

What lug nuts do I need to use with this setup?

I'd also look at the M&H Racemasters... they are incredible from what I understand.

If you order the Weld RT-S from Midwest Chassis, it comes with the proper lugnuts...
