Hello all, i put in a adj pinion snubber and i was wondering if it is helping me or hurting me? the reason i put this in is i went to the track and when id launch on slicks my driveshaft would hit in the tunnel, and i know that cant be good, so i put this in to prevent this, but over small bumps it it hits the rear and give a harder ride,this is when i had some cheap auto parts store springs in the rear, and i just put in moroso drag springs in the rear. i also think how can they properly work if the car cant squat to to much now, it squats but not like it used to. any ideas or opinions?? were the cheap springs the reason why my car squated so much that my driveshaft hit?? thanks in advance..
