I'm thinking about chopping in the S3 for and M3 in the next few weeks and wondering if anyone has gone this route? Looking at the figures for both cars my S3 has 280lbft at 2800rpm and the M3 has 256lbft at 5000rpm, will the M3 feel flat in everyday driving? Flat out it should be much quicker but i like that effortless shove in 4th the S3 has that leaves people stirring cogs and thrashing to the redline trying to hang onto you lol.
