Coil over spring questions.

[CW_MI]

Just overthinking things, as usual. I'm wondering if anyone has done a true dual rate stacked spring set up before, or a progressive rate spring ? Or is it more of a track only type of set up, and not really needed for street driving of these cars ?

I've had dual rate springs on dirt bikes, quads, snowmobiles, and side by sides before. The idea is to run on a softer spring for ride quality, then when a bump or something is hit, the springs couple together for a stiffer rate for the larger bump.

Dual rate spring work well on long travel suspensions. The travel on these cars are 2" or less

Okay, makes sense. That explains why I see them mostly on offroad type set ups.

The subsequent spring rate is the snubber. Oh, you have a snubber, yes?
