Back shocks

SCOTT TILLEY · 02-15-2013, 07:10 AM

I have a '65 ChevyII I run in Super Stock Production with IHRA. It weighs 3030 with me in it. I use a 110 spring. Shocks are behind the rearend. I used a 95# spring for years. I thought maybe the shocks were bottoming out after talking with several racers on what spring I should be using. Turns out that I had no on track performance gain with the 110 spring. Same 60 foot of a 1.31-1.33 with a 327 2 bbl. I did notice the rear was much stiffer with the 110 riding through the pits.
