Never raced before and built my car from a street legal car. Its an 86 Monte Carlo LS. Going to be running a 3/8s mile high banked clay track that varies from tacky to dry slick depending on whether we run first, last or somewhere in between. Min Car weight is 3500lbs, I expect to be over that a little... Fuel cell, battery box, and myself are all on the left side of the car. I bought a 900lb LF and an 1100lb RF spring. Have to order the rears and not sure what to get. Would 300lb LR and 250lb RR be too heavy or not? Would 250lb LR and 200lb RR be to light for that heavy of a car and most of the weight on the left side?? THANKS!

You should not have anytrouble building a metric under 3500#. The front springs sound good. I started last season with a 300lr and a 250 rr but then switched to a 250lr and a 200rr. Thats at 3450 with 54% rear.

Hey o5 Everybody I have ever talked to aroung here run a 25lb split. Do you notice a diff. with the bigger split. I ran 225-200 last year and I think I will go up to 250-225

MetricMonte, you may think about stiffer fronts on that car. I run 1000 lf and 1250 rf, and am getting a 1300 rf for this year. Kept bottoming out the rf when the track was a little rough. It all depends on how you drive the car, what you will end up with. My rear springs are 250 lr and 225 rr. Seems to be the set up for dry slick on a high banked 4/10's track for me. I run a 85' Regal frame/Olds bodied 3340 lb factory stock (ain't much "factory" about it!), and I put it in HARD into the corners. What brakes, who said brakes? Pitch it left and hold on. Hope your first year is a good one, good luck!!!
