The changes to the PP system are huge, dramatic and widesweeping. We're basically starting over when it comes to PP. Some cars, unchanged from 2.09 have lost 50PP. I drove the Roadster at 400PP last night and had to add 40 hp to get it back to 400PP just now. More power for the slower cars it looks like. If done right, it could really bring more cars closer together, but there's no chance of it being perfect with so many cars and variables.
Just checked the RM Silvia...it's 439PP as it sits in my garage...lol. It was in the 490's wasn't it? I remember remarking once that it's about as fast as a top rate 450PP road car and was dramatically overrated, so at 439PP it's much more comparable to road cars in terms of performance, perhaps a little underrated now.
The DTM A4 went from 575>>517PP...lol..
