I note that you haven't added a new set-up since this one? Is that because noone replied?
I would guess that the reasons for the lack of comments lie in the use of R4 tyres, maximum weight reduction, Roll Cage and yet only a Semi-Race Suspension.
Nearly anything will handle well with such sticky rubber because the game engine at those levels of grip fails to function with even a pretense of 'real world' physics.
It is true, as I have recently found out, that set-ups do not necessarily translate up from Sports to Race tyres but R tyres higher than R2 are so outside the parameters of real grip that they pretty much override everything else.
A couple of years on I'm sure you've learnt more of suspension dynamics. Have another go at an RX-7 and see if you can hook in some responses :tup:.
EDIT: Reading thorugh the above I can see that it could sound quite critical. It wasn't meant that way, I assure you
