For me a Golf R would still only be a starting point. 0-62 in 5.5seconds would easily drop below 5 seconds with just a remap. T88OMM has an S3 S-tronic (posh word for DSG!) and had REVO installed at GTI international and did a 4.8 dash to 60mph and the QTR in 13.2 at over 100mph. So, the Golf R is slightly lighter and has the bang same engine. Give it the full Stage 2+ treatment (approx £2,800 from stock)and a DSG remap and you are looking in the face of a 340-360bhp car, 0-60mph in sub 4.4 seconds and a 0-100mph dash around 10 seconds, which equates to a similar performance as.........
Ferrari 612 Scaglietti F1
Aston Martin Vanquish
and faster than........
New Porsche 997.2 Carrera C4S
E46 BMW M3 CSL
Bentley Continental GT
Mitsubishi EVO IX FQ-360
Not bad in my book
