I thought this too but my experience has been poor. I bought mine slightly used (2k miles) and found spring rate way too high. As I understand, their new kit fixes that as well as the loud clunking on harsh/sudden bumps. Also not responsive. YMMV
Used CO kits are always a gamble. You never know how many miles a kit really had. Unfortunately sellers are not always forthcoming with actual miles. I would not buy a used kit unless I planned to rebuild.

Curious as to what Spring Rate you have had?

Ohlins are definetly overdamped, i have them on my car with stretched tires and the ride is rough, if you drive the car for more than 2 hours straight it hurts your butt. If you plan on going with Ohlins make sure you grab the comfort springs from HP autosport and set the damping 15 clicks or above. I would also make sure you're not running a stretched wheel and tire set up, which was my mistake.

I run the TCKline single-adjustable front and dual-adjustable back set-up. The street setting was actually more comfortable than stock so I had to tighten everything up. Now running in the middle setting, which is OEM+. Definitely feels like a proper //M car now (OG M2).

Thanks for bringing up TC Kline. I was gonna go for Ohlins but after seeing the spring rates I think I'm gonna go TCK.

FYI: Ohlins recommends 90/160NM springs for the M2, some people go custom as low as 70/140.
TC Kline offers 53/105 or 70/123.

Considering that most people agree that stock M2 is "oversprung and underdamped" the TC Kline should provide much better ride compared to other kits with higher spring rates.

And the TCK come with camber plates where for Ohlins I would have to upgrade my existing Vorshlag plates.

Summed it up perfectly! It's a great package in my opinion.

Confused.

The website gives the options of 300/400 for front and 600/700 for rear.

TC recommended 300/600 springs for Street for my M2C.

Puzzled now.

That is correct, but it looks like they tried to convert the spring rates to newton-meters

This isn't the case - it's the other way around. The stock springs are comparatively soft (@ ~200lbs), but the car feels sporty as the damping is higher than it should be for those springs.

This is very typical of BMW. One of the things that Apina often do is change the shocks for better matched (e.g softer) damping, and every review then writes about how much better the Alpina version of the car rides, despite the fact it is running the same springs.

Is this perhaps why some people feel that going to a higher rate aftermarket HAS setup such as Dinan offers more "smoothness" on stock damper?

I've got TC's C/O pkg on my car with the 400/700's. ( 1yr on them to date)

For me its fine but for most people the 300/600 would be spot on.

I have the S/A - D/A's.

This is my 3rd set of TC's (E36 & E46 M3's as well) and they have all been rock solid reliable. Single tubes are not as good as the top end twin tubes ....but the twins all require much more frequent rebuilds. I also ran a set of R&T Ohlins in my EVO X with 900/1000's and they also were solid for the street.
If your daily driving your car and will be using it for dual duty these two shock options should work great...

I don't have any experience with M Performance C/O's but the reviews on the forums as you know are good as well.

TC is a good nut, and a die hard BMW Vendor & racer. He dials in his C/O packages by driving on the platforms personally.

Best of luck with what you decide...

Yes, lower damping factors are typically more comfortable. Also the amount of energy stored in the spring that the damper has to contend with decreases as you go up in spring rate. PE = 1/2kx^2 with x being the spring compression. Higher spring rate, means less compression for the same load. The tradeoff with going to higher spring rates is the decrease in isolating ability, so there is a balance to be found.

Ah, that makes a lot of sense. Thanks for explaining. I was scratching my head how going for stiffer springs could lead to better ride.

Actually I have the Dinan HAS and I'm not as impressed with it as most reviewers.

KW Variant 4 is very comfy, just not very good for track use. It"s too soft event in hardest setting

Can you use the TC Kline dampers with stock camber plates?

Having camber plates is nice if you're going to be dialing in the camber but I'd rather keep stock camber plates for the reduced NVH.

Que argument about NVH and everyone's opinion...

For comfort only:

TCKR DA with the lowest possible spring rates(have to run TC's or aftermarket camber plates)

Ohlins R&T with the lowest rates as well(you can run these with stock upper mounts)
