a pain in the pits, CV's will proabably need to be replaced once a year, sound s like the thing is falling apart...( my buddies cup car sounds identical, must 80 %),but it does work great on the track! I know some guys that played around running a spool in an Indy light car, it was faster in the tight corners, especially the hairpin, but they lost time in the long sweepers. Just backwards of what I would have thought. They believe that most of the time gained with the spool was under braking. The rear axle braking distribution wheel to wheel is always perfect. Nice write up Corey.
