Ran the OE, 28lbs, 3.5", .120 wall driveshaft in my wanna be stocker for 100 laps. Decided that a lighter driveshaft would make the car quicker and faster. Had my driveline shop make a 3", .065 wall with smaller U joints that was 12lbs lighter than the OEM. Ran this shaft for the last 50 laps. The net ET and MPH difference.............................wait for it................................................ ...ZERO!!!!!!!! This is in a 13 second car at 3320 LBS. Save you $, light driveshafts are like time trials, very over rated!!
