regarding performace options - I sent my 1999 Boxster to ROOCK Automotive in Atlanta 6 months ago. They dropped in a new 3.4L engine, new performance clutch and greatly upgraded the Brembo brakes. WOW- what a difference in performance. This is the way a Boxster was intended to drive. The cost, while not cheap was well worth it. About 15K for the engine/clutch work and 5K for the brakes.
