I am looking into a aluminum driveshaft. I was just woundering if anyone had the dynotech 3 1/2 or 4" and know's the weight diffrence from stock? Also what the 3.5" can take I plan to finaly crack some 11's next year.
The stock 5-speed driveshaft weighs 21.2 pounds and the 4-inch OD 5-speed driveshaft weighs 16.5 pounds, so 4.7 pounds difference. I measured them myself on the same scale, same day.
