Enough for traction. 18x7.5s I think I would need at least 8 ?? Also drag radials in 18s ??

On what?

I'm running 18x9 or 91/2.. Can't remember...

I also ran into a problem with having to roll my fenders, which was easy, when I went to the 18s.

My lt1 camaro . Up to about 650 hp

I wouldn't trust anything less than 9 inch for that amount of power. But that's me.

And you'll most likely still have some traction issues.

I was thinking the same. 8.5 at the min. Maybe I should just get some torque thrusts at 10.5 wide lol

i have 20x9 in the front and 20x11 in the back and i hook like crazy when need be.

Rub it in......butthole


E: just found out my rear tires are 10.5 inches wide... Happy girl!

7.5 was too small for my STi so it'll definitely be too small for 600hp.

Go big or go home.
10" min in the rear
