My first suspension setup was these Neuspeed sport shocks with HR sport springs, and while the handling was good it wasn't aggressive enough nor low enough. When the opportunity came to trade my HR's for the Neuspeed races I took it up not knowing exactly what to expect. I was scared it might be too rough and too low without enough gain in handling to justify. The opposite the turned out to be true. My first drop left a 2 finger gap and now with the races it went down to 1.5 which was the perfect height for me. The ride even though it was stiffer actually felt like the race springs matched the shocks a lot better. The biggest improvement was the handling. I couldn't believe the difference. The difference of going from the sport to race springs was more drastic then all my previous suspension upgrade (shocks+springs+swaybars). My car finally had that tight feeling I had found in my friend's E46 M3 that I longed for from the start. For anyone serious about handling I would highly recommend opting for race springs over sport springs the difference is very big.
