Wheelies - Hypothetical Combo

Spring energy is 1/2kx^2, where k is the spring constant and x is the displacement of the spring.
Double the compression of the spring, you quadruple the energy.
So even if the rate (k) is half, you still get double the energy because of the increase in preload.

Thats EXACTLY what happens. That stored energy by using a spring with less rate is a HUGE deal in pitch rotation.

IMO, I see a lot of cars at the track that skate of the starting line because the spring rate is too high in the front.

BUT!!! Once you get the spring rate where it needs to be you NEED a good double adjustable shock to control front end rise speed.

As @crackedback posted up above, you can get the front end rising too fast and that’s not good either. You can hit the bump stops and that will unload the rear tires.

So you have to be able to control the front end speed with the shocks. And those 9 way types can not do it. You need a shock that you can tune bump and rebound separately.
