Im looking at getting a set of wheels and tires for street/strip use. I keep seeing guys using 15" weld racing....how do they fit them with brake clearance??? My car has factory 17"...no way to go 15s???

Can't speak to the front as I have 14" brakes, so I used 17" rims. On the rear you need to trim the sway bar mount as pictured here, then it is no problem installing 15" rims.

From this:

Trimmed to this:

Add Sway Bar relocation plates like this:

Then 15" rims fit the rear like this:

What size wheel and tire on the rear? 15x10...275 tire? Thanks again

They are Mickey Thompson ET Street Radials, 325/50/15's.

I removed the bump stop to the side of the frame and re-positioned the bump stop on the axle housing with a relocation plate to make everything work. Here are a few pictures:

OEM bump stop on frame.

Cleaned off the undercoating to see where to remove the spot welds.

Fabricated a relocation plate to move the bump stop to under the actual frame rail. (note bump stop not yet trimmed down in this picture).

I have seen alot of guys using 17" skinnies on the front, to help with steering response and provide brake clearance. Then they use the 15x10's (same brand of wheel) on the back.
 
If you go with the Racestars get the direct drill models. The uni-lugs are a royal pain to use. Racestar even recommend not using the uni-lug on the rear with more then 450 rwhp.
