Hi,
I emailed these guys a while back asking about hubs with Porsche PCD etc.
Here's an extract from their reply:
"All our parts are VW/Audi group based and easily replaced when necessary - rear track is increased by 3mm each side, in our opinion the rear hub is unsafe to redrill to 130 PCD as theres not enough meat on it after machining for the disc, as our majority market is T'3's which run adaptors, it was not viable for us to tool up to make a different hub just for bay's.
Our kit was extensively developed and tested with correct specifications for proportioning valves, pedal/cylinder ratio's etc, its not just a bunch of
parts that work.
I'd be happy to speak in more detail should you wish to do so.
Regards
Chris"
Cheers,
Mike
