Not only that they are hard to drive with those on them. A 1900kg Commodore here with them is rubbish cause they just have so much instant power that they just smoke tyres without even trying with 15% throttle. Yes that can be cool but still not going to be fast in the corners. A big N/A LSX will make around the 600-650rwhp here and 1000ft/lb or torque all around 5000rpm. It will feel like an animal.
