The 'burg was supposed to be a limited run of 500, which turned out to be more like a thousand in the end. The clubsport is the outgoing extreme corsa vxr.
Like the burg, the added extras over standard vxr are:
Lowered Bilstein shocks/dampers
Drexler mechanical LSD
Brembo's front and back
Remus twin exit exhaust system (clubsport)
Different 18" wheels (huge improvement and look mean as fook)
Different map to 205ps
And it did the ring quicker than the Astra VXR...
