If I wanted to swap out oem's to run on H&R Springs, who makes aftermarket struts?
Vendors if you carry them please pm pricing.

Why replace your OEM struts? Those are fine..

I may not, just looking to see if their are better tracking options for those days I do make it to the track.

Not really. If you don't really track the car just leave your current setup.

If you end up wanting to spend more time at the track and take it up seriously then I'd recommended replacing your springs with a full coilover setup.

Until then, you really are fine with how you're running the car.

Trust me, I know how you feel by wanting that full build but when it really comes to practical use you actually have way more than you'd even need now.

Thanks for your input bro. I kinda had a feeling when I didn't find much in my search.

I was thinking of running bilstein b8's for my car before I bought my coilovers. I think they had a set for the c350 which I had assumed would pop in easily for the c63 and match well with the h&rs. I am just not sure if these are stiffer than stock or softer.
