As we promised almost a year ago JCW has released an full US catalog to dealers with the full range of the new 2005 JCW performance parts and accessories. The catalog includes everything from JCW kits and components to performance accessories and even apparel. You should be able to pick up a copy at your local dealer… if they have any left. Prices aren't in the catalog itself but a pricing sheet should be available at your local MINI parts counter.
FYI – for those curious the JCW Cooper Sound Kit is listed to be released this April (no price given). The JCW strut brace however, isn't mentioned at all.
