Larger than stock width tyres, big power, heavy right foot and poor road conditions at the moment, welcome to the winter, the only real way to get traction is be progressive with your application of the loud pedal, I have a big single and a TT and as long as you are careful you are ok, I think actually the TT is more tricky in poor conditions as you are on boost were in the single you drive off boost most of the time due to it not kicking in until 3500rpm, you have changed gear by then (or you should have if you want to stay pointing in the right direction !!)
