I think I have 175Lb front springs on my car now. I'm curious to what an ideal spring pres would be. The car is about 3300 lbs race weight,It currently has lakewood 70/30's on it,probably going to switch to strange adlustables. Rear springs are moroso trick w.adj qa1 rear shocks. I usually run etstreets at the track.

I'm trying to find out if 125 or 150 lb spring would help the car launch better.
