Shortening a Car Coil Spring

[indy4x]

If you are not in a rush you could get some custom springs made up.

I could, was hoping to hack these, do some testing to ensure the spring rate was suitable and then maybe get someone to make a set.

I have an opportunity to take it out this weekend on private land so an ideal opportunity to test it out if I get it sorted

The original rear springs were too soft, the fronts moved to the rear were also too soft. These have larger dia wire and were originally designed to give 7" or so of lift
