Wondering what most guys are running for a spring package and weight percentages on an IMCA Stockcar?

800 900250 22552 rear 53 left 150# of lr bite, if tight in add lr bite, if loose In add more spring to lf or rr. Works for me but my buddy runs heavier front springs and he also wins.

900 LF 1000 RF 175 twenty inch spring LR and 225 RR 55% rear, 53.5% left, 49.5 cross one inch stagger in heat race zero stagger in feature... Sometimes reverse stagger. Pm me on more information, there's some secrets behind this setup.

Did you have to raise your weight jack mount? Why 20” over 16”or 13” it shouldn’t make a difference. But than again I’m brand new to forums.

You can't legally run a 20" spring in IMCA Stockcar

Im not familiar with Imca rules but a 16 inch spring will work with my setup too. Imca47 asked me about my setup in a pm. Your more than welcome to do the same.... I. Dont all my secrets over the forum just the basics. There is a trick to running a taller LR spring though.
1150 rf 1100 lf 16 inch 200 lr 13 inch 200 rr. 54 rear 53.5 left 200 lbs left rear bite. no trick super stiff left rear shocks.
