I was just stating that I have had PSS and KW in my other cars (e.g. Porsche 964 RSA and S2000), and the KWs are FAR better than the PSS system.
These are the ones that I'm selling, as stated above:
"I have some KWv3 for e92 that are new in the box (never installed).
Pix upon request.
$1850.00 (includes shipping to the lower 48 states). Shipping outside the 48 or elsewhere at additional cost."
