Yeah, I bought the bracket from rls in the states and am currently adding lightness via carbon fibre panels. Already done the wheels, airbags and rear panel delete.
If you get the powervamps battery off ebay its only 40 quid.
A set of Volk Rays TE37 saved me quite a few KG of unsprung & rotating mass. They're a much better investment than one might think (a noticeable improvement in turn-in and much quicker round those pesky chicanes in hillclimbs).
