This is as close to real life as GTA Physics will ever get. I am using the same realistic tire properties as before, but this time i tweaked the suspension physics to provide more stability at 300+ kmh. i also changed the suspension settings of the car and optimized the gearbox. Top speed is 419 kmh (260 mph) with 1150 bhp engine. homepage: http://www.moddb.com/mods/realistic-driving-v
