Here are some laps from me, with some comments and comparison to real life.
Production:
8.28.860 - Toyota MR2 Spyder (6MT) '02 (TSracing) NEW
8.26.252 - Mini Cooper S '11 (TSracing) NEW
8.14.722 - Toyota 86 GT '12 (TSracing) Beaten
MR2 spyder is a blast to drive considering its low PP.
Well balanced. I used to have one in real life. Its a fun car. But I have to say its actually better in-game in terms of power and handling. One of my favorite low PP cars.
Mini Cooper S (2010) is actually my daily driver IRL. Like pretty much all FWD cars, not super fun to drive in GT6. There is not any lift-off oversteer in GT6, and lifting off the throttle does not make it turn that well either in GT6. Where its fairly well replicated is engine character. This is a car with lots of torque and power in the mid-range. Like in real life, its beneficial to not rev it out 100% before you shift. I ended up shifting at about 6000rpm in GT6 (not sure if that is the sweetspot) , which saved me some time compared to shifting at around 6500rpm.
Toyota GT86. Super fun car in real life. In GT6 (and GT5) its kinda ruined by the sticky sport hard tires when you get it from the dealership. This is one of the cars that just shows how off PD is with their stock tires. It should have come with comfort hard, or comfort medium at best IMO. (So should many other cars IMO).
With sport hard it understeers a bit more than I would like, and you don't have the power to neutralize the understeer with power due to the sticky tires. "Slow in" and fast/aggressive out seems to work for me in GT6, or just aggressive all the time.. So much grip compared to power.
Speaking about the 86. I had a "competition/comparison" with others in GT5 with the GT86 on the Nordschliefe. My times:
Comfort hard: 8.48.895
Comfort medium:8.33.120
Comfort soft: 8.21.884
Sport hard: 8.11.633
(It also included drifting)
I was a bit faster in GT5 with the GT86 on sport hard (8.11.633). I could get into 8.13.xxx in GT6 if I put more effort in it, but Id rather drive more fun cars, or drive it with less sticky tires in order to make it more fun.
