I run a 900 LF, and a 1100 RF, that is with a front sway bay.
If you don't run a sway bar, I'm not positive but I think you go about 200 lbs heavier on each.
Someone else who doesn't run a sway bar can give a better answer on those rates.

Most of the tracks i race on are 1/5 miles and 1/4's. We found out on slick tracks that those springs are way to stiff. We got some advice about going light and were hesistant. But it works great. We are down to 850 lf and 950 rf on a 3050 street stock. Might want to try this. Ohh and by the way these are too light once you jump to 3/8 and larger tracks.

Ditto here. One of our cars is running 1050LF and 950RF. Car is set up with alot of bite in the rear. Car will drive in great and pulls nice a straight off the corner.

Its been a long time since this car has seen a set of scales. Spring wise it is a 175 RR 225 LR with the LR shimmed about 1 1/2 inches.(most of the ballast being to the left and middle....NO RR ballast.) If I remember correctly, last time we scaled the car, we had about 180ibs of rear split but thats been last year. We don't have very good access to scales, so we make changes based off of performance. This set up was too tight in the middle until we change the front springs. Now it works well.

dtd_93, JDF, I've been thinking about trying this type setup. The track is 3/8, medium banking, and usually tacky. What I've read suggest reverse split works well on flat or low banked tracks. What's the tracks like were you race this setup at?

I have said that several times on here, 1200 on the left front and 1000 or 1100 on the right front really works well in some cases. It helps from mid corner on to getting out of the corner which will get you down the straightaway quicker.
