This car is great, I don't see any need for assists to be used. I don't use ABS and TCS but it still handles fine, it can kill you if you go full gas in 2nd gear but overall it handles great and will whip other cars around the same PP
(i actually use it at 650PP) like the BMW F1 GTR and Fairlady Z LM and it will compete against the R390 GT1 at 650PP. I also used it at 630PP and it was still great.
