I don't know the cost of the KW CS but why not also consider the RS1 damper with street-biased spring rates or wait for the Ohlins R&T suspension to be released?
I'm using the RS1 with 400/672 and 500/800 rates - the ride is not at all harsh on the street even with 500/800 rates. With 400/672, the street ride and performance are greatly improved over stock EDC plus the rates are stiff enough to still have fun at the track!
The Ohlins R&T comes with ~350/~680 rates. With the DFV technology, this damper, and rates, will make for a great DD ride with improved overall handling performance compared to OEM!
