Well maybe something like in NFS Shift that you can't downgrade your car or the host can set a manufacturer event and everybody has the same car.
How so? Power and weight are messed with in real racing. And cars can be modified to fit certain rules. The Viper had to lose its V-10 for a V-8 to be eligible in some series. Nothing's wrong with PP, though it shouldn't be the only option.One make races is a good idea and should be an online mode, but would get old after a while so there needs to be more.
the GT5P pp system is a weak way to solve the problem and ruins the realism
That's exactly like PP, except you're restricting tuning to tires only.Maybe PD can classify all the cars depending on their performance
NASCAR
Rally
Prototype
GT1
A+
A
A-
B+
B
etc etc
Cars that fall into the 'A' category all are within a second or two of eachother. To equalize the performance one car should get softer tires. If the tire difference has to exceed 1 compound in order for the cars to be equal then the car belongs in a difference class. For example if one car has S3 tires and the other has to have S1 tires for a fair race these cars should not be in the same class. If two cars run equally with one on S2 tires and the other on S3 tires then they should be in the same class.
That way when someone sets up an online room they can say "B+" cars only. You look through your garage and find a car that is rated as B+ and enter the event.
Just something I thought up real qucick
