I am new to this forum and have a couple of questions for you guys. I have a 05 CLK55 AMG Coupe.

Which suspension kit is the best out of these? Any better let me know.


1. Carlsson RS Sports Chassis Suspension
2. RennTech Suspension Kit + Lowering Kit *
3. Brabus Suspension Kit +Lowering Kit
4. Kleeman Suspension Kit+ Lowering Kit

Also which performance tuning is the best out of the following? Any better let me know as well.

1. Carlsson
2. Renntech * 530 HP @ 5800 RPM /// 548 Ft.Lb Torque @ 2400-5000 RPM
3. Brabus
4. Kleeman

* = Installed Already

Money is not an issue right now. Just want the best parts and performance for my car. Also what is the best size tire for this car? I know on my M3 the best size is 19”. What about these and what size tires?
