To start with the elephant in the room, the pricing from all vendors is absolutely criminal. 2/3x mark-up because the stock ride height is an eye sore. It’s close to passive coil over setup cost and halfway there for future EDC coil setups.

This said, I’ve test driven a stock M2 and I was very happy with the way it felt and handled. Lowering springs are generally hit and miss, sometimes they even ruin the ride completely. Aftermarket springs for this car are almost all (if not all) G82/80 M3/M4 derived so the spring rates will not be ad-hoc for the platform.

This said, out of all the ones on the market, what’s the general consensus? As objective and un-bias as possible please. KW Has, Oem Has, MSS hybrid Has, Eibach

I cant offer too much in the way of info as i dont even have my car yet, however i ordered mine with the M performance HAS kit. Pricewise it was comparable as the kit itself is 1700$. The KW HAS kit is 1400$. They added 1000$ for labor costs. When i got my coilovers installed on my 2016 BRZ, i was charged about 1400$ from my shop to get them installed and an alignment. Thats 100$ delta and for me getting it from factory with BMW warranty on it was worth it.

I can only assume that BMW designed their HAS kit to work exceptionally well with the car so i cant imagine that it would change the ride significantly and make it worse.

Get the BMW MP HAS. It's essentially the same price, but comes with the BMW warranty.

I don’t trust local dealers to do a good job installing them so I’ll most likely end up doing it myself. What happens to warranty in such a circumstance?

As far as the oem M springs go, they’re built for the G80/G82. Not a fitment issue but those cars have different spring rates than the M2. So is it really the right fit? The MSS kit somewhat feels like a better buy as it (at least says) keeps the spring rate comfortable and not too harsh

As has been stated, get the M Performance HAS aka sport suspension (these are made by KW but if you are concerned with warranty, get the M Performance). Here in the USA, best deal is port installed. Not sure if that is sn option in Europe.

Evolve's stance kit, static springs, worked for me. Ride is firm but not too different to stock. Less than 1/2 the price of a KW HAS kit where I am.

Yep this right here if available to you OP.

[FrankWhite!]

I was able to get the HAS kit port installed and the car looks so much better with it plus as others have mentioned you get the warranty and it rolls into your financing. For me, the ride is outstanding it’s not too firm whatsoever.!

The lowering springs are one of the best mods for this car. it completely changes the look.

I use H&R adjustable springs on all my M cars, in my opinion its the best daily driver option.

[mzimand]

I am with Mike. H&R adjustable springs worked great on my G87.

Hey, is the port-installed HAS kit $2700, and is the part number: 31305A2D979? I wanted to add this to my build but the car has already started in production (long story.....). I'm working with my dealer on having them install the HAS kit after my car is delivered. I want to make sure their price isn't out of line ad ensure the product page they sent me is the correct part number.

Also, after considering other options for suspension upgrades this to me is quite cost-effective and very appealing since the parts will assume the 4 year 50K mile BMW factory warranty.

Here is the fine print on your warranty question:

*Original BMW accessories that are installed on/in the vehicle will
carry the full New Vehicle Limited Warranty if they were installed
prior to the delivery to the client.If the installation is made after
the retail sale of the vehicle, the accessory will be warranted for
the balance of the New Vehicle Limited Warranty period, or two
years from its date of installation, whichever is greater

But to clarify, the part would be warrantied but installation and other parts related to the suspension would not be as it was not installed by BMW. Its not out of the question (being kibd) that you may not be covered if something goes wrong to a suspension related part id BMW did not install the HAS.

To be expected, unfortunately car is almost here and wasn’t aware of the port option

Although in all fairness, my dealer would probably not even know how to get aftermarket performance catalogue items installed at port

With warranty out the door, KW HAS sounds like the go-to option. MSS based on reviews doesn’t really inspire much confidence and their pricing is not very competitive.

G8x M3/4s have been around for quite some time now, how come no EDC coil over kits being developed by KW or Bikstein?

I hear ya. It's hit or miss with dealers here too. My situation is that my car went into production 1 month early and I wasn't able to add the HAS option. My dealer will install the HAS kit before I take delivery of the car. Working with them on getting a quote for parts + installation and hoping it's in line or better than the $2700 people pay for the port installed HAS kit.

I have heard great feedback on KW products and if I was going aftermarket I'd go with them.

Pretty sure most dealerships actually charge more than this, that's just the port installed price.

That's what I was afraid but after telling my sales guy the HAS is a port-installed option he was to figure out how to add it to my build. Pricing was $2820 to add the HAS kit.

Ya that's all in, parts labor etc. If he has issues he can ask a more experienced CA but shouldn't be an issue to add as long as it's not too late in the process.

My CA didn't know that items could be added like that and it was his first attempt at doing it. Looks like it went through as I see it listed under the "Added Options" section in the production tracker. Another great example of getting insight and help from these forums. Without the forums I wouldn't have known to ask for this option.

That's awesome. Glad to hear it was straightened out!
