Radbull tire is Nitto street legal, not slick. In drifting, it's not only about power, you can reduce the power in Radbull, if that matters. What I'm trying to say is car behavior, in general FR with short wheelbase like Miata. If Radbull is too extreme, then the BMW 1M or Mustang or any road car FR layout will decent power should do. My prime concern is how the FR car drive when initiating a drift with different technniques, how it shift weight ( throttle and steering play ), how the tires loses grip, how the car maintain an angle, how the driver could manipulate the cars while sliding, holding, increase the angle or do transition ( direction change ), how clutch can be used, how handbrake can be used, and importantly how tires react throughout ( temp changes, grip changes, feedback ). The setup also gets attention, like spring, damper, caster, toe and camber, which most games do not translate well when not gripping on road. I doubt GTS will improve much from GT6.
I've had
@Mike_grpA tested and did the final setup on the Radbull, there were issues with tires ( grip while in angle slide ) and alignment on the car and how it behaves while drifting. I'm pretty sure on low powered car like 1M or mustang, it will be similar, how the tires regain grip and maintaining angle while drifting behavior. My interest is if he tried GTS with similar car, how much difference in behavior it will be with likes of AC and Pcars, that could be rough indicator of how much GTS improves.
