Its all good ssqpolo - The reason that it may become a problem is because of the clutch engagement. The mass of the stock flywheel allows you to engage the clutch at low RPM's and without much jerkiness. The inertia of the spinning mass (flywheel) counteracts the clutch as it tries to clamp down, therefore allowing for smoother, gradual engagement. If you get rid of that mass, then the flywheel will slow down to match shaft speed much faster (jerkier) and you may sometimes stall if you aren't being careful or giving it enough revs. This is a common issue with the Carrera GT, the drivetrain / flywheel is so light that engaging first gear can be a tricky endeavor. Often people don't give it enough revs...or too many.
By lightening the flywheel AND the pulley, you are making it even worst. Some people would advice that you do one or the other. Usually it is better to go with the flywheel because there's more performance to be gained there...However, on some cars, it is OK to do both...Hence my question
