I’m quoting from personal experience, not from a TV showVARIANT | one wrote: ↑Tue Jun 26, 2018 1:10 amThis is not true. I think this is some stupidity spread by the dumbest of the three idiots on Top Gear. Downforce raises at a square of the speed and effectively raises the Cf of the tire at the same curve. It's progressive. So long as your tires are up to temp, the point at which the car begins to oversteer or understeer is the highest speed you will achieve in that particular corner before the tire starts to slip. Most aero cars are dialed in with aero understeer, with the CoP ~3% behind the CoG.
