How soft can you go with front springs? Was at a very black slick track and was running a pair of 900's. Took the right front down to a 800 and this made a difference in the right direction it seemed. I guessing that we can go softer yet with booth springs. Is it because of the slower corner entrance speed that the lighter springs will transfer more? We went to another track that was dry slick and tried 800Land 750R, it really seemed to help corner entry, when others would lift the throttle we could just go by them and dive in front before we lifted throttle. It seemed to really help the front braking, Imean you could really feel it plant the front to the ground with the weight transfer. Are the USMTS guys doing this? By the way I was getting 4" of travel on the right front, would softer springs and more travel be better or would I be going over the edge? I realize I dont want them to bottom out.

Monster, all of the old-timers used to tell me "just use enough spring to keep it off the dirt, sonny" and I typically run with a 650 LF and a 750 RF. I stepped up 50 lbs. each on my leaf car and they are telling me now that the small metric GM's take a little more front spring... I guess it has something to do with the leverage ratios built into the lower a-frame.

On the early chevelle frames you can run a softer spring because the spring location is closer to the ball joint than a metric a -frame.Usually you have to run about 100 # stiffer on a metric car

Try 200-250# stiffer!

I have seen the difference between LF and RF at a min of 100 lbs and a max of 200. mostly a diff of 100

Depends on the type of lower control arms and chassis width.(i.e wheel rate)
