Whiffbitz had their Time Attack FD for sale on ebay. Dunno if its still there, last time I looked (couple of weeks back) it was around £12,000. I believe it's road legal too. The dyno chart for that thing is on the wall at Surrey Rolling Road, tis a mighty impressive machine.
Back on topic...I still want an S2k....even if it is going out of production. I would love a copy of the J's Racing or Amuse tuned S2k...*sigh*
