Currently the GT4 series is balanced around the 2016 Audi #17 Rotek Racing TT RS, which has a PI of R802.
The problem is this car is not GT4 homologated vehicle. It’s okay that the car is in the GT4 series to fill the class (putting at a whopping three), but it shouldn’t be the baseline. This has been mentioned in multiple discussions, but now there’s a topic to vote on.
The 2019 Ginetta G55 GT4 has a stock PI of S723 and the 2018 KTM X-Bow GT4 has a stock PI of S750. These two are actual homologated GT4 cars, so the BoP should be based around these cars with a target in the S730-S740 range.
The Audi should be rebalanced (restrictor plate, ballast and other balancing) to match the performance of the GT4 cars if it’s staying in the GT4 division.
