Lighter Wheel weight than stock BSA wheels, decreasing rotational inertia, thus allowing quicker starts and overall times. Can be run as is, or polished with Novus / plastic polish to remove micro scratches. You choose! This set of wheels usually yield an increase of speed by reducing on average 0.02 seconds in time with properly tuned car. Listening to a set of these wheels run, you can tell they are in a league of their own!

On a Builders NOTE…. You will need a set of pliers to pull the axles once installed. Because the wheels have been ligthend, you can no longer pull the axle out by the wheel. You will bend/warp out of round. Then the wheel will not roll correctly and you just wasted $$$. Please dont let this be I told you so moment.
