Hello Dave (Stratosboy), I am really interested in your rear handbrake install!
I also have an S1 with engine swap, also have AP discs (295 and not 308), and also a Lotus 2 pot caliper.
I saw you choosed the V2 (and not V1) version of the SVA spot handbrake range, and I red that special brackets are needed but the very question is: INFORMATION on this bracket!!!
Do you still have your drawings of this install???
I would be SOOO cool!
