Here's a quick list of upcoming JCW accessories for the US and their timetable for release:

JCW Cold Air Intake
First some good news – the JCW Cold Air Intake will be available as a standalone JCW accessory later this year. The intake should give around 5hp by itself. We should have more info soon.

JCW Seats
Now some bad – it looks like the JCW seats will not be offered in the US due to safety concerns. It's unclear if this is due to the lack of seat mounted airbags or something entirely.

JCW Brake Kit
The brake kit is still under development. No timetable was given.

JCW Suspension Kit
These kits should be available in the US by middle to late october

2005 JCW Works Kit for the MCS
The one that everyone is waiting for. As mentioned previously the new 210hp kit should be available in the US sometime in October. The first batch is en-route to the US as we speak.

The additions to the Works kit will be available as a retrofit kit for all previous model year JCW MCSs.

The other JCW accessories available in the US will be part of a JCW catalog released later this year.

Much of this info was sent in to us by an MA that recently attended MINI training in Minneapolis.
