Let's get GT1 and GT3 class cars in the game and offer Race Mods for those type cars (standard & premium) already in the game. And yes, when you race mod a standard car, that car comes out a premium. That might be hard to do but it should happen.
Expand the car equipment selection filters in on-line racing. You should be able to allow or disallow Transmission, suspension, drive train, exhaust (in and out) turbo/supercharger in addition to what is already there.
Create a GT1, GT2 and LM,LM R classes for on-line racing. Also, allow for races against different makes stock of modified. Unless the manufacturers wont allow it.
Put Special Stage Route 11 back in GT. Put Silverstone (all configurations).
Just take a look at GTR2 track and car lineup. Game gets boring without new track challenges, and expanded car lineup and control of car modifications.
Please bring back the GT4 LSD selections. Let us adjust suspension settings on each wheel. Put the speed shops for each manufacturer that has them. I.E. Mazda Speed, TRD, RUFF, Calloway, Salen, Nismo, Shelby and so on. That is where you would take you car for tuning and Race Mods. Wake up PD.
