no doubt it will. good luck with your endevours.
to run the 150mph race does the car need to be street legal and registered? 150mph = roughly 240 - 250kph. i cant even do 120kph without the doors falling off.
150mph could be done with slight mods and a looong strip. (ohh by the way how long is the strip? or is it a continuous circuit like nascar?)
so are you changing the final drive or swapping in a competition gearbox? i think the b6t with uprated boost will push 150mph with a bit of effort, sounds very interesting. post a vid of your run, will you?
make sure to tape up all your panel gaps, take off the wing mirrors and screw in the hard top tight!
best of luck, mate
