what is the ultimate front rear percentage. we started out 61 front 49 rear we had to add weight to get up to 3300# now we have 51 front 49 rear, car handles good but we are 180# over. any advise welcomed.

I would shoot for the rear % like 17j said and loose some of the weight and try that.

where is your weight mounted now try moving it as far to the rear of the car as possible that may help. also can you run shims or spacers in the rear springs if you raise the rear of the car that will help. another thing where is your battery mounted if it's not in the trunk and rules alow you to move it there thats 75# that you can use back there without adding any more total weight

It's very important in a metric if you want it to bite,i've seen 54 % rear without nova lowers and it was fast.Try to get the weight off the front,i use an aluminum hood and i try not to add alot of bars to the front,then try not to hit anything...

another thing you can do, if rules allow it, is move the engine back. on a metric car there are two sets of holes to bolt motor mounts in. its like 1 1/4" back. you will have to beat the firewall in. gain of 2 to 3 percent rear. also your stock drive shaft should still work.

Drive it in deep, and come out hard!!

group 24 batt weighs 37/ a large marine one might get to 45.

moving the motor back 1.25 will gain only .2-3 if your lucky....

i'd move that battery ahead a bit and put the weight where the battery was and put her on the scales and see what it does
