if i was racing someone from 80-130 does that mean i would loose, or does it just mean i would run out of gear quicker. Are you for real with top speed only being cut to 165. If so i'll do the mod. I just dint want to loose all my top end, but i have no plans to take the car above 160 on just z rated tires.
btw, reason i want to keep hicas is cause i'd rather just keep it hooked up to a switch to turn it off and on at will.
