When I drive a car for fun it has to be nice to drive.

As you say they pull away horrible, maybe that's the flywheel weight being the problem?

I don't think your flywheel is as light Trev, as said half standard is probably the limit but I suspect 2-3kg might ruin a road car.

I have a paddle on normal flywheel and that is like a standard car to drive, I just try not to slip it as I think that is not good for them.
