The spring rate is calculated to support the weight of the car in this case E90/E92 ( we have different spring rate for M3s), while the strut handles the damping.
There isnt an universal kit for every car since the spring rate, lower mount setup, and even the suspension setup is all different.
Rear of the E90 | E92 is a little pain since the spring and the strut is separate, usually it takes us 45mins-1 hr to adjust the backside.
Good thing is once the coils sits, go back to it once and you never have to go back to it again.
Can you elaborate more on a few things.
1. What the spring rates are for these?
2. Where the adjusters are for the damping? Top of the shock in the rear, underneath in the front, etc.
3. What is the lowering range?
Thanks man, these look really interesting and I do appreciate the emphasis on comfort.
