I've been researching lowering options for our C43 coupe and see that KW now offer a height adjustable spring kit (coilover springs) for those who don't want to go down the complete V3 coilover route.

Very tempted as this would give some extra adjustment over the fixed drop H&R option.

Thanks for posting this - I assume that this would also fit the C300 4Matic, shouldn't be any difference?

Tuono

You would have though so, but the C300 isn't listed for some reason in the compatibility list in the link I posted ?

I would be wary of assuming these springs will work on the C300. From what I know, the AMG models use a different suspension from the standard C300 suspension, so it may not be a direct fit. Someone correct me if I'm wrong here.

tblountman

Pretty sure you are correct...

Also, the 4MATIC models require a different set of springs compared to the RWD versions. H&R makes a different set specially for 4MATIC use. Something to keep in mind when you guys are shopping around for springs.

Jesse Jericho

The C43 only comes in 4Matic. Unfortunately H&R hasn't released springs for the C300 4Matic, only the RWD version. They keep telling me they are "two weeks away".. :P

Actually if you look at the bottom of the page, all of the 4Matic models are supported:

The only caveat being that it is "only for vehicles which have electronic dampers". All of the cars would have this, no?

RUNSGR8

I don't think non-AMG cars have electronic dampers. We have the regular, traditional spring-shock system suspension.

Jesse Jericho

The "AGILITY SELECT" is standard on all C205 / W205s, as far as I know, which uses electronic dampers to change the ride characteristics (amongst other performance modifiers). Correct me if I'm wrong.

RUNSGR8

I think those settings only affect your steering weight and throttle response. They don't affect your suspension unless you have AIRMATIC.

Jesse Jericho

AIRMATIC doesn't use springs like that, as far as I know.. it uses an air shock like this:
