Selecting coilover lengths
Turbo Mini Forums

What is the general principle of how to choose a length?

This is for my SD1; I've welded Mk2 escort bilstein coilover struts onto the rover hubs, and know I want to start out with 450lb springs.

All I can think to do is put solid pipe in there to get the ride height I know I want, and put some scales under it to get an idea of weight at the front end, plus the mcpherson angle, minus the un-sprung weight, and try to work backwards.

What I'm not sure, is how much compression is "ideal" when sat on flat ground at . 25% 33% 50%?

Ah!!, the million dollar question,lol

I’d say you would want to go for the shortest spring that will get the job done, so you stay away from the possibility of it going coil bound. Use a helper if needed to keep it on the spring platforms under full droop.

i tend to go for around 1.5 to 2" upward compression of the spring as you let it off the jack .

Medusa + injection = too much torque for the dyno ..https://youtu.be/qg5o0_tJxYM
