Curious as to what Spring Rate you have had?

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. |

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

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. |

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... HAZMAT

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.

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... |

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) |
