Considering one of the above for my M4 Comp pack.
Best to worst?
First hand experience only.

The GC HAS seems like a really nice kit since it comes with camber plates, adjustable sway bar links, and the spring rates of your choice from Eibach (which GC can help you choose). Had I not gotten a great deal on my KW HAS, I might've gone that way.

I had the KW HAS kit..gave the car a great stance however, the ride was terrible. Swapped them out for the KW V3's and it was the best money I ever spent. Don't waste your money on lowering springs..just get full coilovers.

Why terrible ride with the KW?Too firm?bouncy?

MP HAS is designed for your car....just sayin

With the stock Comp suspension, even in comfort mode, it was pretty stiff. I know that it's a sport suspension but to me, it was still pretty rough. The KW HAS (and any other HAS kit's) only lower the car. So basically, if it ran rough before, it's only going to be rougher since you are lower. With the KW V3's, you can adjust compression and rebound, which means you can adjust how stiff or soft you want it in the front and rears. Not to mention, since I put the V3's on, the car handles a lot better. It's is incredible how much of a difference it makes. So, this is what I meant about not spending the money on the HAS kit if you are looking for better ride quality. I was just use that money towards the V3's or something similar that gives you more options and allows you to tailor your suspension to your own liking.

if you are implying that the 2 kits are identical with same spring rates then you are wrong

Not what I said but just because something is OEM doesn't needs to be the best.

Believe they advertise 0-30 mm. I wasnt looking for a slammed look just wanted it to look clean and I’m super happy with it. Ride is amazing

IND. Had them in stock and shipped out immediately. There are other vendors in the US that well then but they basically get it shipped from the maker. Takes more time to receive.

I have the MP has kit on my car and honestly the ride is the same as stock but it doesn't go that low in the front.. I'm thinking about going a tad lower but I'm maxed in the front .. If I would do I again I think I'd do a coilover.

I really like my ground control kit with EDC dampers. I haven't tried any of the others but the flexibility of the GC kit is really nice.

Do you miss the edc control at all?

Not at all. I have the suspension set where I like it. However, I do have an appointment in 2 weeks at Manthey-Racing to get it really dialed in. I'll post after it's done to let you know how it rides and handles.

Yes please! Keep me updated. I'm putting on the v3 this week and i was worried I'd miss the edc. But i believe the v3 allows you to control the dampening too right?

True, but OEM have financial, engineering and testing means that most aftermarket providers simply don't have. I prefer going OEM when I can for that reason.

I have finally installed KW HAS KIT.
Rear springs are linear 685 lbs, so same as comp pack.
Front are progressive, so hard to compare as stock are linear to my knowledge.
This is where I don't like it.
Car is smoother than before, less harsh for sure.
I am checking if I can find a camber plate that can work with 70mm ID springs, so I can get linear springs with proper stiffness, or I will remove the KW HAS and sell it and go back to stock CP springs .
Car rides very well, but I liked the feeling of stock springs

Hey I am looking at KW HAS as well. What specifically do you not like about the progressive springs?
