Hypercoils and Underbody Protectant

[AP1995V6]

I'm going to be picking up the MM coil-over kit, and I wanted to get some testimonies on hypercoil length and spring rate to see how you guys like it and here some first hand experience on different set ups.

Also, I have a few rust spots starting under my car and I'm going to sand them down and cover them. What sort of paint/coating should I use?


Thanks

how are those 10" 300lb springs? Rough on the road?

a little spongy for my tastes. i have eibach pro kits on the rear and the front feels a bit softer, although i have adj struts that have made up for it.

i want to go to a 400lb spring to get a better spring match front to rear then be able to fine tune the shocks/struts
