My Porsche 911 Carrera 998 setup. Has 2% intake reduction and 15kg added mass all on front to give it same weight and 1hp of the power of the real car. I also changed the gear ratios for realistic acceleration (based on halfway between what the car really and Porsche says it does) and top speed. I havent tweeked anything else so the only handling change is that all the added mass is at the front to make up for lack of computers that the real car uses to make up for the light front.
