Correct wheel spacing can improve the way your car handles, increase corner speed and reduce lap times.  This all adds up to winning races. 

Adding or removing a wheel spacer is a lot more cost effective than having different offset wheels and takes up very little space in the trailer compared to wheels and tires.

Wheel spacers are a must for the serious racer.

This spacer is 1 inch thick and fits 5 x 5, 5 x 4 3/4 and 5 x 4 1/2 bolt patterns.
