How have you guys set up the suspension on your IX's?
I've used stock springs/shocks.
Stock springs/Billy HD's
& H&R springs/Billy HD's.
The H&R/Billy combo wasn't bad, but it did lower the car and it is still a progressive rate spring.
I'm from the world of road course race cars. We hate the unpredictability of progressive springs.
My newest IX I just order a complete kit from Ground Control with 430F/600R linear Eibach springs and Billy HD's. My goal here is winter DD and occasional rallycross. I want stock height for the winter time with maybe a 1 inch drop for the summer.
I know someone listed all of the factory and aftermarket spring rates for 80's-90's BMW's but they only posted the inch/pound rate for the first inch of travel. This is kind of useless information to me since they are progressive rate springs...
Has anyone tested the amount of ramp-up on factory springs? How progressive are they? (cuz they feel like poo)
