KW Height adjustable spring kit for C43

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.

http://www.kwsuspensions.co.uk/kw-he...ngs-45039.html

I've also been in touch with Eibach and they are working on a specific lowered spring set for the C43, but it won't be available for 3 months.

I've been hunting for these in the states.

adjustable spring is the perfect compromise on this car.

I have lowered my C450 estate with coilovers KW Variant 3, and placed wheels Ispiri FFR6 with sizes 8,5jx20 ET 42 and 10jx20 ET 45. Tyres 235/35/20 and 275/30/20 Yokohama Advan Sport. In the front i had to place 12mm spacers for clearance of suspension arm.

I'm very satisfied with the way it looks, and the way it drives.

Looks awesome, I'm looking into a 20" Ispiri wheel set up myself and the KW HAS kit for my C43 Coupe! How would you say it rides compared to the oem set up?

I just got a note from the KW Sales and Technical Advisor stating that there are no immediate plans for release of these in North America. He didn't state why. I guess if anyone in NA wants them that bad, they'll need to order/ship from EU....or wait until who know when

I was hoping to have the option to raise the car a few mms when I get it dropped.

Would also like some opinions or comparisons to H&R Sport Springs

I have been hearing that the HAS has a tendency to make clicking sound when turning the car which apparently gets really annoying.

I've got the KW HAS kit installed on my C43 AMG Coupe, there is a lot more room to drop than the H&R springs. I have the rears maxed out at around 35mm and still a fair amount to drop the fronts more. I've found no clicking noise when steering and no real difference in ride quality - I really rate the kit.

This is more likely associated with improper install. I have heard this and it's usually the result of binding springs that are not seated properly at the top hat, etc.

Congrats! Does it affect the ride quality at all? Are you pretty satisfied with them?

I ended up raising it about half-inch because of some of the rubbing issues. Will post some new photos when i get a chance. "Rubbing issues" is a bit strongly worded. regular driving no issues. If I hit a large dip fast, i hear some scraping...and also had some challenges driving during the winter....so raised the car to avoid that for the next snowy season.
