That seems pretty soft on that RF, think rayburn recommends 500. And may want to try and get front weights closer together.

Is your push on throttle or off? Just going in, or all through the corner? Where are your rear bars/pull bar set? Stagger? Track condition: slick, tacky? Give me more specifics and I can help you better.

Generally, get that RR bar all the way down, add stagger will loosen car. If you have adjustable shocks add rebound and decrease comp LF. Can also stiffen RR spring, Move pull bar in, take LR bar up. These last 3 will take away bite, but let it turn on throttle.

with those wheel wt's your at 47%front,48.1%l side,53%rear and 53.4 cross total 2084 # car, that must be with out driver. ours was 2350 with drivers wt in the seat. you need to stiffen the rf spring and soften the lf so you could switch them but the 400# spring may be to soft for the lf also.we ran the 500# springs across the front a 350#lr and 275#rr.oddly enough the car scaled at 495 pound lf and 500 pounds rf we ran 120 pounds of lr with 56 %rear.

after double cheking those numbers were off, I checked again using the cal.off the pro shocks web site and it can back ls 53.4 cross 48.08 rear 53.023 total 2084 31#lr just as listed below. that new comp program may be wrong or I just didn't understand the resaults.

get left side percent at 54% with driver. Increase rf spring to at least 475#. Try 125# of bite.

x2 on what master's built said. I wouldn't soften the LF, unless stiffening the RF doesn't do enough. Take the RF up to 500, and if you have adjustable shocks add rebound LF.

But your Cross is way low. Racin's calcs are backwards, you're at 53.4% left, only 48% cross, which is way low, no wonder it's pushing. You need to get that RF weight up. As with others I'm assuming this is with no driver. Here's the exact weight breakdowns with the info you provided:

Total: 2084 Bite: 31 Left: 1113/53.4% Rear: 1105/53% Cross: 1002/48%

for reference our (newer) rayburn (with driver) is 500 across both fronts, 54% left, 54% cross, 57% rear, 194 bite. post your weights with driver in.

From rayburn's setup sheet:
5. Rear percentage 56%; Left side 54% (+ or – ½%)
6. Wedge (cross) should be within 2% of left side percentage
