don't know what version of GT 6 the setup was done . But it was a good tune regarding the default Dino behavior.
My impressions driving in GT6 1.09v:
I thought the back was too unstable for high speed corners and over steering a lot when stepping on the gas (even when gentle on the throttle). Also the rear was rolling a lot when I tried to trail brake into medium speed corners.
Also the turn in was too aggressive, making the car go sideways very easily and lose traction momentum, because I had to wait to regain grip.
After a few runs and a few tweaks that is my suggestion to improve handling and corner speeds and make your tune work even better (if I may):
Suspension
Ride Height (F/R):
90 / 95
Spring Rate (F/R):
6.20 / 7.80
Dampers - Comp. (F/R):

I would like the author to test it and tell me what do you think?.
