What RF spring is everyone running on average?

[ask0329]

Metric clip, Metric lowers and spindles. IMCA mod, dry slick moderately banked 1/3 mile track. I run 700 LF and 750 RF. 225 LR and 175 RR. Car is good in heat race when track is tacky and smooth. Come feature time 95% of the time its black dry slick. Car tends to skate a bunch and be loose. Using up all but 2.5-3" of the RF shock Thinking of dropping both front springs by 50Lbs and see what happens. Also going to try dropping ride heights by an inch or so. I've been told that an all metric front ends need to be ran a little lower than Chevelle clips due to the metrics being "taller".
