I was looking through summit racing last night and noticed they carry circle track wheels, similar to the one's used in Nascar. So since I'm never good at picking out a set of wheels for neither of my cars, would these be OK to run on a road course Camaro?

My car is an 1989 IROC-Z and I'm going to build it into a non street legal track car... for SCCA racing. I've just decided to do this so I'm not up to speed on rules and whatnot. Still have a ton of research to do... but... for the time being I'd like to pick up a set to install Slicks on. Since they are affordable. Now, another question... what are the advantages and disadvantages of running a 15" tire versus a 17" tire? Is width more important than sidewall height?

Someone shoot me in the right direction here... thanks!

forget the 15" wheels .... you can't get BIG brakes under them !!

Not entirely true.. but it will limit how big of a rotor you can use.
Nevertheless not everyone needs a 13" rotor / 6 piston caliper brake systems unless you are planning to build a car fast enough to actually use them

There are plenty of dual piston kits that will fit under 15" wheels which do a great job.

I have single piston front dual piston rear manual brakes and the car stops just fine from 127 MPH.
granted I am only going in a straight line


also be mindful you are not buying "wide 5" wheels, the bolt pattern is completely different.

My point is.. figure out what SCCA class you plans to compete in.. and design the car based on that...

and before you buy wheels make sure they are 5 x 4 3/4 B.C. & not WIDE 5 bolt circle.

remember on these cars that the stock front wheel have different back-spacing.

and FWIW why if you want a road course car or cone carver the stock alloy wheels are a great choice if you are on a budget: 15x8s or 16x8s
