I've looked into the issue of MR cars in 500PP.
To give as fair an idea of the situation as possible, I put two different MR cars up against two different FR cars. These tests were done online using only upgrades and no fine tuning and were all done on Racing Medium.
The cars:
Challenger SRT8 '08
Fairlady Z (Z34) '08
Clio V6 24V '00
NSX Type R '02
The observations:
The Challenger and Z were absolutely lovely to drive. You have to be an idiot on the throttle to really upset these, they are just so planted in all corners. I am actually considering changing to either of these because of the great handling.
Then came the Clio V6. At 500PP, it's not stable at all and I'm pretty sure I spent more corners sideways than I did pointing at the exit. Even then, it was 3 seconds faster than the FRs. Not until I had lowered it to 450PP were they on the same level.
So when I came around to the Honda, that was what I was expecting would work here as well. But no. At 450PP, even though there is all the grip you could ever want (you basically only need to brake for Turn 1 and the hairpin), it was just too slow on the straights, barely reaching 200km/h before you brake for the first turn.
Everything taken into consideration, I see especially these three options open:
1: Ban MR from 500PP but potentially allow them to enter the 600PP class instead
2: Remove the PP limit from all classes and instead introduce a minimum lap time
3: Continue to allow MR in 500PP with a generalised handicap
