Thanks guys for all that info.... much appreciated

So after looking at the caliper it looks definitely a 1 pot rear.

Is it worth upgrading to a 2 pot rear? I kinda like the looks of it much better but I only use it for street use, not planning to do tracks or anything like that, but am planning to put VF34, injector and tune soon, I've already got TBE and STI intercooler in.

Where would I be able to source the 2 pot caliper to suit GC8? And would it fit the DBA rotor I already bought? It's the HD Gold series

Thanks again guys
