Need help from the suspension gurus here!

So you went from 100 lbs/inch to 250 lbs/in. That is a significant drop in stored energy. I changed torsion bars from 1.19 IIRC? to the slant six bars. High 290’s lbs/inch to 100 lbs/inch. Went from no movement to full transfer of weight. With the big bars it just barely twisted the bar at all! It was a street car then. Also you took weight off the nose. I’ll bet that spring is barely compressed at all, requiring the tire to do all the lifting.

I'm not an expert here so I could certainly be wrong but according to the guys at Menscer when I wanted to run a 250 lb spring he thought that to be ridiculous as that would probably compress the spring some with the weight of my car and upon launch would aid in a wheelie or similar movement which he said is not needed or even wanted especially when you have really good shocks......I currently run 400 lb springs and still managed to pull a significant wheelie but I have a lot of power along with 4.88's so there is that.
