For the guys saying ''what does it matter''....bore off
For what it's worth, my bog standard gti was all over a 07 330d in the twistys, when it opened up i was still on his tail at 80/90 then he left me like i was stood still. Those cars are properly quick above the ton mark
I'd say a stage 1 gti circa 250bhp would be around the same as a 335d upto 80/90ish...after that no chance
