Default Which Springs give you the best drop?

Hi guys, currently i'm in a dilema in lowering my car. At first I wanted to get the H&R lowering springs and cut it to get the agressive look but after I think it again, the ride will be terrible. So I decided just to use a lowering springs without cutting it. Which springs do you think gives the best drop?

From my research:
-H&R springs F 1.2in R 1.2in drop
-VOGTLAND springs F 1.4in R 1.4in drop
-Eibach only 1.0 in all around
-Intrax springs? how much lower?
-Cobra springs (dunno yet, still got no info from them)
-H&R adjustable coils, kinda pricey though, but it gives up to 2.0 drop at the lowest setting
-Brabus springs? how much lower?

If there's any other option for me, please let me know, thanks a lot guys

What do you want? Lowering for the gallery, or maximum fun and driving comfort?

If you change the springs only, your car becomes hard and uncomfortable. Because of the short springs your buffers are not working in the best range. Better to take a complete chassis with shortened buffers and springs.

Good and cheap springs you find at www.weitec.de
The best chassis you find at Bilstein, itīs the B16 Pss9

I have brabus springs, lowers it about an 1", the ride is OEM like. H&R will be just a little bit lower, should be stiffer than brabus. KW coilvers will give you the most aggressive drop.

Here's what brabus looks like.

I just need the look, I don't really care for comfort... probably I will get the H&R coilovers... do you know where can I find the bilstein coilovers in USA?

thanks

I believe the number he provided is for the bilsteins

But nevermind, I just browsed through KW website, and found the KW Variant 3 for the R171 and the price listed was 2150$

Yes, I thought they would cost more or even twice.

as did i!!! i used to have KW variant 2's in my old Audi and they were fantastic! great drop and amazing handling. if i was willing to go all out i'd opt for te KW coilovers. however i only wanted a slight drop to maintain comfort, so went with eibach springs and am more than happy.

Good for you, I am keeping my stock AMG suspension setup though.

Hi,

I had H&R Springs with modified lowering before. Look was nice, but the car became a little stiff... (first picture)

Now I have KW coilovers version 3 (second picture), which gives a perfect look, and a perfect ride...

Best regards from Germany,
Werner

Hi Werner!
I also have the KW type 3 on my SLK but I could not find out how and where to adjust the dampers according the installation manual. I have done adjustment on the top of the dampers only. Rebounce I think. How about the bump adjustment? Any tips?

Hello!

I try to check the weitec website, but I didn't find any kit for the slk

I would like to lower my car but I don't want a race kit, the streets in Italy are too bad!
