Its quite difficult to get the older S3 off the line quick, they tend to bog down if you don't get things just right. But that isn't my point, my point is I've owned both, a 2000 S3 with APR stage 1, and now the ED30 with APR stage 1, and in the dry the ED30 is quicker all round. In the wet its a different ball game. I'm not really fussed if you agree or not, but from first hand experience this is my opinion for what its worth
