New KW Coilover Kit for E30 M3

[mwagner10702]

If you are a member of the SIG you will have already seen this. For the rest of you Bimmerworld has announced a KW coilover kit for our E30 M3 that doesn't require modification to the front strut. The spindle is forged and comes with the knuckle, and the strut is already modified (threaded) for the adjustment collar.

Here are the links for V1 and V3 variants

This is appealing. Any idea if there is weight savings between either variant and the stock setup? Anyone run this setup yet that can chime on comparing them to other coiler options such as JRZ?

[Brian H]

Exciting, I'm tempted

Here is what James Clay provided as a sort of comparison with MCS. IMO I'd go MCS before JRZ any day. I have the MCS 2WR on my NSX and they are fantastic.

MCS:
- Part of a customized package
- Monotube with pressurized gas cylinder (in the canister - or non-remotes in the body)
- Both adjustments on top, which is sweet - and often means you actually adjust both - lots of people buy thinking they's adjust it all and on a
100+F track surface in a driving suit the reality is the one you have to
crawl under a hot car to reach rarely gets turned.
- Really primarily designed as a race damper that can be driven on the street - but I'd call the 2WNR even more track focused than the rest of the brand (I have them on my E92 M3 because I wanted double-adjustable for some reason, but didn't want to deal with canisters on a street car).
- Aluminum rear housings for weight, steel front (plated), spherical bearings in rear - good for precision - not great for winter salt use
- Lots of low speed control and oil through holes design means each adjustment adds a specific amount of additional oil flow by uncovering holes for discrete adjustments.
- Fully rebuildable in GA
- Requires a core

KW:
- Suspension in a box - pre-configured and ready to bolt on
- Twin-tube design
- Rebound top, compression bottom
- Stainless bodies and rubber "silent blocks" in the rear for good salt resistance for more street use
- out of the box really focused on performance street use, or street/track for V3 (but certainly track capable)
- We race essentially a V3 on the M240i Racing. It's got different valving than a street kit, and can often be rebuilt, but sometimes we just replace
- Rebuildable typically in CA
- No core required - and we THINK (still waiting on confirmation) that the steering knuckle is included

I'll be ordering a set of the V3.

last what i have heard was that they are not available at the moment
production have not started.... they only have shown a few prototypes.
But i think they will come in the next weeks.

Price is ~800 Euro more then the "older" versions where you must give your old struts back for the modification

[El KuRLy]

Anyone knows the length of the front struts? In case for those that have shortened the front struts to gain/have damper travel.
Thanks!

The MCS and the KW V series are 2 different levels of dampers. I've serviced several sets and own MCS dampers, serviced and own a couple of sets of Ohlins DFV, have serviced JRZ, AST, MOTON, Penske. I've opened up some KWs, they're similar to the twin tube JRZs I've serviced. KW typically does not sell service parts- you have to send them in.

This is interesting as it may bring down the price of the used stock strut body. I, too, am curious about the length.

Mike,

The KW solution does not require any modification of your existing struts as they are not used at all. KW is manufacturing both the strut and (I believe per James Clay) the lower steering knuckle. This way you keep your E30 M3 front struts intact and unmodified.

[evommm]

Yes that’s great I was gearing it to the mcs setup

Are these the same struts as our cars if so what $ do they go for?

[mwagner10702]

are these the same struts as our cars . . . ?

No.

[stevesingo]

Do I understand this correctly?

KW have offered their existing suspension on a non-exchange basis, i.e you don't have to send thenm your struts?

Given BMW have started to reproduce struts, why is anyone surprised tha this has become an option?
