KW Street Comfort (P/N 1802000S) for F30 xDrive: any experience / feedback?

Did anyone install KW Street Comfort on F30 xDrive sedan? Please share feedback.


From http://www.kw-store.com/products/kw-...ort-13946.html


KW Street Comfort BMW 4 Series F32 435i Coupe AWD (x-Drive)
Part #: 1802000S
Availability: Please call customer service.
$1,869.99


Description
KW Street Comfort: Individual sport suspension with Maximum comfort
Height adjustable Street Comfort allows a lowering of 10-40mm depending on the vehicle. This allows for the flexibility to improve the look while adding custom products like aftermarket wheels.
At the same time the lowering has a positive effect on the driving dynamics and road contact. With this discreet but effective lowering more spring travel will be retained to combine a comfortable spring with harmonic dampener, this way the best driving comfort is guaranteed.

KW Street Comfort BMW 4 Series F32 435i Coupe AWD (x-Drive); without EDC
Lowering
Front Lowering: 0.6" to 1.8"
Rear Lowering: 0.8" to 2.0"
Notes
02: Front height adjustable by threaded shock bodies. Rear height adjustable by adjustable spring perch.
37: Vehicles equipped with electronic damper control: Electronic damper control needs to be disabled. Disable modules available through KW. Please check KW accessories list.
67: Valving is adjusted by adjustment knobs, rebound is only adjustable if the top of the piston rod is accessible. This will depend on the design of the vehicle.

I dont have the exact experience you are seeking but I did install KW V1s on my Audi S5. I LOVED the ride and handling! My only issue which seemed to affect some others was that the rear sagged much lower than the minimum drop they advertised. KW sent me spacers then a different spring which solved the issue but I am bit worried about this happening again on my 428i GC so I am on the fence. Its strange that the rear ride height issue does not impact everyone.

We had them installed on an F34 (GT) and the customer was extremely happy when he left. PM me if you want a quote on them.

I've been riding on Street Comforts on my 13 F30 sedan now for about 2 months. Previously I had H&R springs. The difference was huge, I am super happy with how these coilovers perform and the comfort level that I regained from getting rid of the springs. Plus the adjustability is a nice perk.

Thanks for the feedback on this. Did you have something close to the advertised range of adjustment? There have been some comments about other KW's that the rear has been too low at the highest setting.

@pbittner,

Thanks for the feedback. I am also interested in the adjustment range.

- What was the final suspension height vs OEM ride height?

I am looking to maintain OEM ride height as much as possible.

Just an FYI for the guys looking to maintain OEM ride height or close to it. Bilstein makes a Comfort version of the PSS10 for the F30/F32 that drops the car between 10-30mm. The part # is
48-229012. This is what I am going to get once something is released for the F36.

In the rear I have the spring perch adjusted out a quarter inch to give me a finger gap between the tire and fender, there's a lot of thread left to go higher if I wanted. So to me it seems just as advertised.

I don't remember what the OEM ride height was but I am at 25.75" from ground to the fender lip.

Appreciate your comments @pbittner. Can you compare the ride and handling with your SC's to the OEM suspension?

Well, it's firmer than stock that's for sure but not to the point of being annoying/rough and vastly better than say just running springs on stock struts. I really like having the adjustable struts so I could make it as firm or soft as I feel like, even though it is a little bit of a pain adjusting the rear struts (requires removing the strut from the top mount or going through the liners in the trunk). Overall, I am extremely happy I went with the SC's for daily driving.

Just ordered KW Comfort Street coilovers for my 2013 F30 xDrive sedan from Turner Motorsports. AllShocks.com (a division of Turner Motorsports) sells this kit for $1589. The kit will be built in Germany with a lead time of 4-6 weeks. Will update this thread after installation.

Thanks for the info! It's the cheapest online so far and I ordered one too. Can't wait to put it on the car

KW Street Comfort coilover kit was installed today on my 2013 F30 335i xDrive with all four shocks set to 9 as recommended by KW. The height was set to maximum in order to approach OEM height as much as possible. No alignment needed.

Initial impressions are very positive. Will post another update after the suspension settles.

The shop advised to me that coilovers may make some noises when the car goes over bumps but the noise is normal.

Thanks for the update. I'm still waiting for mine to arrive...

I'm surprised KW recommended the rebound to be set to the 9 (that's the stiffest setting right?). Is the ride overly stiff in that setting?

May I ask what what is the install shop's name and the cost they charged you?
Thanks

Did you install KW Street Comfort coilers yourself or the installation was done by a shop?

In my instance, the installation was not done properly and another shop had to redo the entire process.

At full suspension travel point (rebound), the spring should still be in a compressed state. If it's not, the spring will float and generate "clunk" sound. This is a very common scenario.

Things to verify ...

- Was the spring properly preloaded
- Was everything properly torqued especially top nut (using an impact wrench during removal and installation is NOT recommended)
- Is there a chance of spring bind? More about spring bind at https://raceland.com/news/what-is-spring-bind.html
