It was in the latest GRM?? I missed it.

Roughly speaking, ITR starts (with some justified anamolies) at 190 stock hp and goes to 240 stock hp, purposefully excluding the S52 BMW motors.

ITR and the power/weight ratio was 'built" around the 189 hp E36 325is at 2750. This was a mistake, as it effectively made all of the other cars in R too heavy (for the most part) and prevented us from including in R a number of cars in the 240-250 stock hp range since they would be ridiculously heavy at those numbers.

I can't speak for the whole committee obviously but the idea is that we bump R up a bit, reduce the power/weight multiplier so existing cars lose some weight, and we include some of the 240/250 stock hp cars in R.

At the same time, there is a realization that many of the tweeners in R/S -- the MX5, teh Celica GTS, the RSX, the TSX, the Civic Si belong in S as they are heavier curb weight cars and more esaily make weight in S with a full complement of "racer stuff:" cool suits and radios and such.
