Really really reaaaalllly pay attention to what mazda matt said. It is way too different from your supra to go at it blind. If you lose control of the front don't gun it, it won't even out like a rwd would ease the brakes and regain traction. If you lose the rear put on the gas to even it out. Have you tested to see if you get any torque steer out of your new configurations? You may have to physically compensate on that part. Read up on the Scandinavian Flick for desperate situations, and to more fully understand how and why brakes helps your cornering in fwd. And if at all possible Pics and Videos. Its not likely in your VW but most hatches have a tendency to go 3 legged on tight turns so don't freak out if you notices a slight change in your steering when this happens, 3dr hatches have a certain structural quality that helps maintain and control it. plus its extremely fun to watch spectator faces as you hike up a leg around a corner.

edit: iirc only the early rabbits did this, recently the yaris liftback has shown this attribute but I don't believe the golfs have achieved it.
