Summit Racing.

I will warn you, they are a bitch to mount. You will need tubes, which means drilling the valve stem hole bigger on the wheels. That is why you want a crappy pair of wheels.

Do not even try to mount them without tubes. I wasted a whole day, and went to every tire place in town before I realized it was impossible.

Makes going to the track a lot more fun. Car wants to sway a little bit on the track, so be careful.

my tire place didnt have any problem mounting my slicks on a cheap pair of 15x7's that i had lying around... no tubes...?

I had no problems with my 15x7's either. 20x8's on a 14" wheel; could not get it done.

he mights have had slicks that where designed for tubes man they are out there. You need to read carefully before you buy. imo
