100% street use on my wife’s e92 M3. It literally felt like you’re driving a car with blown dampers. Zero control of weight transfer in normal braking and cornering. It took forever for the car to finally take a set. It wasn’t the spring rates because I was running Moton SS on my other e92 M3 with similar F/R 350/620 lbf/in rates. Additionally, it had poor control of wheel motion and impacts. It felt like you were on a boat in choppy water which is what made my wife nauseous/car sick. Even with rebound maxed out, there was no improvement. I’m the first? I find that very surprising.

I had used Koni yellows on my ‘00 s2000 when they were first released and they did a very good job of controlling/minimizing body motions and wheel disturbances. Their performance on the s2000 was the main reason why I decided to try the TCK SA setup on the e92 M3. There weren’t many street suspension options in 2011-2012 for < $4k which also factored into my decision. Ohlins R&T weren’t released yet and it would have been my first choice for an e9x M3 street setup based on my experience with the R&T on my R56 Mini CS. Based on my personal experience, I would not recommend the TCK SA or DA setups for the street or track.
