I believe the 2nd number is just the lot code or build week gentlemen.

Would also like to know some leads on where to order with updated rear springs.

Should I just buy straight from KW?

Here's a photo comparison of the v1 (34H21) and v2 (13H22) rear springs, note this only applies to G80 M3, as G82/3 M4 isn't affected. In the past, we were including a 15mm spacer from KW to account for the difference and is no longer needed with the 13H22 spring.

34H21 length 11 1/8"
13H22 length 11 3/4"



The difference is very subtle, but gives the additional lift needed in the rear on G80 M3. All G8X KW HAS Kits from us are now equipped with V2 rear springs, spring spacers are longer needed.

Forgot how much I hate doing rear springs on jack stands….

Car is perfect now, IMO. I must have had the original setup preloaded like a mofo using the 15mm spring spacers. Now, it rides A LOT better. Much less bouncing, and much smoother.

Some pics with the new springs, sans spring spacers:

That looks perfect. How do you have it set up in the rear relative to max and min height?

Do you have a side view photo?

I'd say they're both at about the middle adjustment. I can go higher/lower in the rear, same for the front. Maybe another 1/4" higher/lower.

I think I do. I'll have to dig through my camera.

Did you find any side view photo? How much is your drop front and rear in mm/inches?
I'm also curious if anyone knows the difference front and rear fender gap in stock height?

Sorry about that, here you go. This is the best side shot I have. And I honestly never really measure the drop. For the front, I just kept it away from the max lower measurement, and really just fine tuned the collars for the right look.

Took my car to Speed & Tech to have some carbon installed and have my ride height adjusted. I felt like my car was too low and driving around in DC was a pain in the ass.

The front was raised 5mm and the rear 10mm to match. I have the KW Spacers installed. Here are the before and after pics:

Before:


After:


I have to say, the improvement in ride quality and handling feel is night and day.

Ride quality is vastly improved -- very similar to stock. At the previous ride height I felt the car was a little too bouncy to be able to use comfort mode, like the rear shocks couldn't keep up. Now the car feels great in comfort, sport, and sport+.

Raising the front slightly seems to have helped with steering response as well -- initially after lowering the car I felt like I had lost a lot of the super sharp response and urgency at the front end... feels like I've gotten some of that back.

Overall, I think this car really doesn't like being slammed on these HAS kits... the oem shocks don't seem to keep up. But at this ride height it feels fantastic, and still looks really good. I'm thrilled... it feels like I got my car back.

That's some great news! I noticed a HUGE difference in ride quality once I put the v2 springs on the rear. Car seemed much more OE-like.

LOL!! Sometimes I'm not sure if I'm happier with the carbon OE setup or truly miss the MPE and regret selling it.

So yeah, please don't remind me...

Maybe just get the M Performance tips? I didn't start liking them until I saw them on the 50 Jahre. They're money, but they're also titanium.

Funny you mention that, I looked at those right before buying the MPE. I’m with ya though, I still consider them. I’m waiting to see what the Dinan exhaust looks like though.

Great writeup and you are correct, it rides better not so low. Once I switched to V1 springs and raised my rear mss springs it rode perfectly

I have a question for your setup. Are you at 20mm in the front now and 10mm in rear? I'm installing BC Forged wheels tomorrow and purchasing eibach pro kit. I hate my MSS springs and adjusted them to this setting and although it initially rode better, I'm still hearing noises and noticed paint missing so I k kw they are binding.
