On a normal racecar, if you're too critically damped, then the car will tend to "hop" (imagine if your car had a solid bar in place of your shock, it would be extremely harsh and bounce off of bumps). Thus, your wheel will constantly be losing traction. The same happens on the other end of the spectrum - if your compression is too low, then the wheel wont reset fast enough, so on bumps it will spend a lot of time in the air, thus losing traction. |

I was planning to get Ohlins but was recently told that they require a rebuild every 19K street miles or 10hours of track time. I can't imagine getting them rebuilt every year.

That is the one big advantage of the Mperf coilovers. Get them installed at dealer and they are covered under warranty. Plus you can get them for $2k, about $1k less than R&T.

Its coming for f8x.
I wonder if the tractive coils for the F80 will work on the M2. Then you can install the DSCsport with it.

I have got the m performance coils on my m2c.
With my setup and adjustments they are not as stiff as the stock suspension in the lowspeed fraction but when the dampers need to work fast, it is stiffer and firm. Exactly what I want. |

unless you're a pro racer, the difference between ohlins r&t and kw v3 will not be felt by the average driver. they are basically in the same class. m perf coils also fall into this category, but there's a limit to how low the height can be set, most likely to preserve warranty if installed by bmw.
i had the v3 on my m2 base, but will be getting the ast 3 way setup with a little stiffer front spring for the m2c (also a true coilover in the back). the dampers on the v3 were good enough for a occasional track days, but the spring rate was a little too soft for the track. ohlins rt, kw v3 and m-perf coils are all tuned for street-first, track secondary use. they're great for spirited canyon carving and the occasional track day, while being able to live with them on the daily commute. however if the ohlins do require rebuilds every 30,000km, that seems pretty poor for something labeled "road and track". |

seems ast provides a plate to disperse the force to the body. the 5200 rear design looks similar to the front top hats, but with three bolts. |

Nope, the stock top shock mount is with three bolts. The AST is just a top mount adapter for their spherical end shock. Its best quality is the road noise.
