i have comp eng 3 ways on the rear of my car set at 50/50 with trick springs, tubular control arms (non-adjustable), all in stock locations. i'm wondering if i should set the shocks to a firmer setting to try to plant the tires a bit harder. anyone running their shocks at 70/30 with a similar setup? my car has gone 1.65 in the 60'...but has since slipped about .05 since installing the rear trick springs, for whatever reason.
