Mine are the Moto-P spec units with rubber top mounts and not pillow balls.

6 months on them so far and no noises.

They're a lot like a 'Type RR' or '///M' setup vs stock. Feels very much like a tuned-from-the-factory, OEM 'plus' style set up in terms of street/track capability. They don't like extremely rough pavement very much but neither does the stock car. Most bumps and undulations get soaked up as well as stock without unsettling the car. On most road surfaces I've been on other than construction sites they ride great - well behaved enough that you completely forget they're there.

Handling balance on the stock out-of-the-box RS*R damper settings with a good alignment is superb on the track and a huge step up from the stock units. Neutral, understeer or oversteer - biased cornering balance is entirely and completely up to the driver. The chassis responds very crisply and purposefully to steering inputs and the car corners very flat while still letting you transfer the car's weight around all 4 corners of the car very intuitively. Nice blend of composure vs. agility.

In short they're well worth the money IMHO. Excellent street/track shock. Near OEM ride quality, better versatility and all around performance than the bargain basement coilovers out there and simpler to set up than double adjustable units without giving up too much in terms of ultimate performance.

I like to think of them as a sort of 'poor man"s Ohlins'. If I were competing for trophies I'd get some Tarmac IIs or KW V3s (or Ohlins) but I'm not, so I'm very happy with these.
