Hi. Will the GT4's ABS and PASM systems adapt to/tolerate differences
in front and rear tire diameters, of 2.2% without reacting incorrectly
under heavy braking or cornering etc?? I have few competitive tire
options to play with, in the race rules.
Thanks!

 

I'm not sure about the latest softwares, but the earlier cars needed to have the tire diameter programmed in. You have a good question because at lower speeds it is probably not an issue, but 2.2% at 150 mph is a much bigger difference than at 20 mph. As I think about it I will say ... adapt, NO ... Tolerate, maybe. That probably wasnt much help
