The link explained exactly what you have said, the original debate was the fact that your car has less grip than an S3 off a wet bend 0n full throttle(which the link does not detail).
Funny you should mention it, but I dont think the internet has an independant test for S3 vs M3 in the wet on full throttle.
The link, and my post explains how (drivers aside, so lets assume compentant drivers in both cases) the M3 would absolutely be faster out of a wet corner than the S3. I actually think within the confines OF the corner, so turn to apex to turn, the S3 would be quicker, however, if we take into account the lead in and lead out, the M3 would be FAR faster.
