Q: What are the details of the M4 M Performance Suspension?
A: The M4 M Performance Suspension maintains the factory adaptive EDC function and uses your factory struts to retain adjustability depending on driving experience mode selected (comfort, sport or sport+). It’s paired with stiffer springs and a revised bumpstop tuned for better performance. It comes with an adjustable perch for height adjustability (from 5mm to 25mm drop). The kit is developed in conjunction with KW and it is based on their sleeve-over suspension kit. The difference with the BMW M Performance coilover kit is the M Performance Specific spring rates, bumpstops, and assorted hardware. As with all BMW M Performance Parts, the factory warranty is retained when installed by a trained BMW technician. The springs are manufactured by KW specifically to BMW M’s spring rates and the kit has been tested on a four post rig and fine tuned at the Nurburgring. The reason why retaining EDC function was important is because the take rate on EDC is 70-80% on the M3/M4 in the US.

For your reference, the M4 on the SEMA floor is lowered 20mm

Is this accurate? I think it's a bit funny all the naysayers to dropping the car (I'm one of them), stating they don't want to mess up the 'BMW engineered', millions of $$ and hours developed, balanced OEM stock suspension with some aftermarket springs, and here's BMW literally just rebranding one of the aftermarket products as their own with minor changes. I admit I'm fairly interested in this, simply due to the OEM brand and warranty. If the car pulls to one side, has uneven tire wear, etc etc, you can just take it back to the dealer and say, 'fix it'. All this while gaining some feel, performance, and looks. The only x factor is the cost. If it's anything close to a real coilover system, why bother?

I, too, wonder if this is going on the comp pack...

I agree, I am on the same band wagon as you, I have always been cautious about altering the spring damper combination. This sort of confirms that the EDC is able to adapt to varying spring rates. I still wonder if BMW will recommend those for the non-adaptive dampers.

The main benefit I see with the MP coil-overs is that they are built to BMW specifications. BMW have the complete chassis design and development test data at their disposal. Which makes them better suited at selecting the appropriate spring rate and bump stop height and rate.

This sure seems like a sweet combo .

They did aid in the development ......

The acs springs cover the warranty for the oem shocks for the duration of your Bmw warranty

So the only difference is that these are height adjustable

From the picture the front springs look different. Too early to speculate without all the details about the product.

I don't know how they're going to warranty this.... The M2 M-Performance coilover looks like it has a HUGE amount of perch travel. You should be able to Stance Bro Nation that thing.

Pretty cool option vs. KW HAS or other aftermarket. Where are the camber plates though?

The M2 coilover is a true two way adjustable coilover. (Compression and rebound)
Pretty cool for M2 owners to have that option right from bmw.

So wait the MP Coilovers being released for the M4s basically works w/ M Adaptive and allows us to drop the car a bit based on what we want right?

Since this is actually my first time thinking about doing this, what is the difference between this and a full suspension swap?

Since you say you're new to this area of modding, I recommend you do a lot of research before making any decision to modify your suspension. There is a lot of information and research available on this suspension forum alone; start with the sticky master thread.

But to answer your question quickly... It depends on your wants. If the drop you want is between 5mm and 25mm, this kit will satisfy that part. Secondly, this is a far from a full suspension swap. It is just a spring swap and adding a bit of height adjustability to the perches. You also get new bump stops.

For crazier suspension swaps, check out IND's M4 and the M3 with the Ohlins TTX coilover in the master thread.

The availability of the M Perf coilover sleeve kit for the F8x is still a ways out. I encourage you to get to know more about the topic before the time comes.

Wow, surprised they are offering a true coilover on the M2, and surprised they didn't on the F8X. Great news though, I'm glad BMW is making the cars track-ready from the factory!

Not quite "from the factory" , but at least with full warranty and dealer serviceable .
