What’s up fellas, just picked up a 21 M4 Comp 2WD with carbon buckets. Been reading about suspension. I had an F82 before this on Eibach sportlines. Had swift, then switched to the Eibachs. They didn’t lower the car as much as I like but it rode quite well. I hear KW HAS springs rode better at a lower height than the Eibachs. It’s quite pricey so I would hope so. Has anyone here owned both? I’d like that Eibach sportline ride with H&R height….what do you guys recommend? HR, Eibach, KW HAS, AST….thanks

H&R VTF is the best, in my opinion. I have had their kits on both G82 I owned.

Excellent drop and ride quality

Have you had anything else on any other car? I ask because of all the springs I’ve had iver the years on all types of cars, I always come back to Eibach sportlines. All the others are either too bouncy, stiff or both.
Thanks

I had MSS on the same car. No Eibach unfortunately

I went with HAS springs and switched to Eibachs on my 22 RWD. My car rides better and although my rear set lower and looked better, j prefer the Eibachs. No more noises and binding and also not scraping on speed bumps and maneuvering in and out of turns. Pick your poison but if it's a daily, take that into consideration.

If i had to pick between Eibach and KW, i'd choose Eibach as well

I have Eibachs on mine here. It’s an Xdrive as well.

It’s pretty low…other than coilovers I think Eibachs are it. Anything else would be too bouncy of stiff.

Called Eibach, they don’t make a sportline kit for M3/4 at all. Pro-kit only and it’s for AWD and 2WD M3. You can do fronts only also. What happened to Eibach? Going to have to roll the dice and pray the ride isn’t horrible with another brand. A buddy installed AST on his M3 Comp AWD and hated them. Switched to Eibach, wonder if that kit would work correctly since there is no specific kit for M4 2WD from Eibach. Maybe H&R or KW HAS is the way to go I guess…who’s on HR or some other brand in a RWD M4 that can chime in?

If any m3 needs eibach springs I have new ones for sale, shipping from Canada though, link in signature.

There are a few threads on here talking about Eibach springs. I got my kit from AutoID (Europe). I believe R44 also sells them as well.

Here is my car with Eibach front and rear springs. I think the rear sits a little higher than I like but my car was aligned with a more positive offset to save the rear from going through tires so fast. This may give it the impression it is higher... I don't know

Tell me that’s some wonky lens distortion in that top pic…that doesn’t look right to me at all.

Here's another one... it must be my camera. It doesn't look this way in person.

Not sure Eibachs would look right on a 2WD coupe. There is no kit specifically for M4 2WD. Worried it won’t look right or even handle correctly. Spring rates are specific to M3 and M4 xdrive. Debating KW HAS or H&R.

There are specific kits. Just not sold here in the US. There are plenty of pics on this forum of people on eibach with your type of car.

R44 has m4 kits, they fit 2wd/xdrive https://r44performance.com/products/...2&_ss=e&_v=1.0
They lower 20mm front and rear, i can probably get a better price for these if you want.

[Izzmeister]

I’ve had Eibach on all my cars. Mever disappoints as far as ride quality but never drops it enough IMO. Wondering if HR rides the same or close, drop is perfect. KW HAS also, perfect ajustable drop but how’s the ride quality? Another forum member swears by KW.

Looks like you have positive camber in the rear.

Actually my camber is set to -1.50

It might be a little bit too late for OP but I was in the same position, got M4 Comp RWD and wanted to install Eibach because I dont want to be too low to the ground. Did a lot of research and came to a conclusion that AWD kit they sell in US (E10-20-049-09-22) comes with exactly same front springs number F11-20-049-01-FA as the RWD kit in Europe (E10-20-049-01-22). And European kit is the same for AWD/RWD models. So I figured it is worth a try ordered and installed E10-20-049-09-22. Fits perfectly, rides beautifully (honestly I don't feel any difference between Eibach and OEM)
