I couldn't find much information on these but I wanted to put a quick review up

The coils have a 12kg front and a 10kg rear spring rate. The rear spring rate at a stock height seems way to high. Rear end is incredibly bouncy.

Im going to lower the rear slighty and see if that helps or lower the spring rate to 8K and maybe move the rear springs to the front for a 10kg/8kg set up.

This is coming for a air suspension. I feel like the spring rates are for a VIP stanced car. I dont know how much being at a near stock height effects things.

Quality of the unit seems good, no excess noise.

TBD
