C55 control arm upgrade
My C55 needs control arms.
FCP Euro sells a kit for $425.00, but it says it fits all C230, C240, C280, C320, C350, CLK320, CLK500, CLK550, C55, etc

I'm surprised the AMG cars didn't have a different part number.
Does anyone make an upgrade kit?

As far as "upgrade" kits go, FCP Euro themselves sell these:

Powerflex makes poly bushings:

If your control arm joints are still good and only the bushings are bad, you can do like I did and just replace the bushings for a fraction of the cost of the kit you linked to. I personally wouldn't run any poly or ball bushing on my lower control arms. Typically a terrible ride quality/NVH compromise and increased impact shock to your steering gear. Nothing is free.
One of the OE bushings can be "upgraded" to later W204 OE bushings though without really much compromise to ride/NVH. I did so, and can't say I notice any difference in ride/NVH or performance, just hope the bushings last longer.

Yeah, for a daily driver I may as well stick with the stock ones.
My wife's E90 328i M sport handles significantly better which makes me jealous, but my car is more comfortable and the handling isn't bad by any means.
Plus the upgrades are damn expensive. You can actually buy an M3 control arm kit for the 328i that is the same price. That's an easy decision.
