i use a pinion snubber with ss springs and have had O issues. when still the snubber is about 1/2-3/4 away from the floor. good for 1.48 60' outta my boat. tried back to back test with it on/off and the car would loose about .15 just on the 60' with it off and picked it right back up once i put it back on, everyones combo is different as i know mine def is, but it works so i leave it alone.
