Hey,
Physics wise the car seems okay, I have not built a 288 model so I cannot really comment on any mechanical aspects. I trust that they are reasonable.
However I feel there could be a change done to the tires, specifically the load curves.
It seems that the dropoff in the Stradale's road tires is quite aggressive. Typically longitudinal side has much less dropoff than lateral. I made some modifications based on your original lateral mu value and the spec of the tire.
I suggest trying these:
FRONT:
DryLatLong=(1.297,1.23215)
LoadSensLat=( -5.40E-5 , 0.62 , 12000 )
LoadSensLong=( -2.57E-5 , 0.81 , 12000 )
REAR:
DryLatLong=(1.297,1.23215)
LoadSensLat=( -4.76E-5 , 0.62 , 12000 )
LoadSensLong=( -2.26E-5 , 0.81 , 12000 )
I feel that there are other things as well that could be done to push the model more, but I think this is a worthy change. I'm reluctant to comment on much else specifics as I've been away from gMotor for about a decade soon and I might be misunderstanding the parameters. I think this is about correctly implemented though.
I can't comment on the Corsa's tires, apart from that a slick tire likely would have somewhat less load sensitivity, due to overall "more tire" being available.
Apologies for modifying the car even if the files request that it is not done, and apologies for critiquing a relatively old release in case this has already been changed internally. I hope you don't mind.
EDIT:
Oops, noticed I forgot to change the 2nd parameter in the fronts. Correction:
LoadSensLat=( -5.40E-5 , 0.5869 , 12000 )
LoadSensLong=( -2.57E-5 , 0.7935 , 12000 )
