i need to get a better launch at the track and i saw a post a long time ago about 15" prostars fitting are cars. i'm looking at weld prostars 15x9 ... 5x4.5 bolt circle .... 5.5 back spacing. does anybody know if that is what the g's and z's are using ?

 

There are plenty of 15 inch drag racing wheel recommendations in the drag racing forum.
