Whilst researching BC coilovers I had a quick look on their main website (as opposed to their UK importer's one). It appears they have just bought a new series for the Roadster called the V2 (in addition to the BR-RA, BR-RH, and RM):

The website is in pigeon English, but it appears the V2's will be a more basic version of the BR series - they will retain adjustable damping force and ride height, but you need to reuse the top mounts front and back (so no pillow ball).

No sign of them yet on the UK importers website ( m http://www.bc-racing.co.uk/c-bcc18/toyota-mr2-zzw30-00/ (http://www.bc-racing.co.uk/c-bcc18/toyota-mr2-zzw30-00/) m ), but would be interesting to know when they will be available and what the price difference will be compared to the BR-RA.
