Actually good value when you brake it all down.
A standard (non-carbon) BBK kit would set you back a few grand for a car like that and then an set of rear silencers would probably set you back another 2-3 grand.
So you're basically getting and engine map, suspension upgrade, diff and traction settings for free. :D :cool:
