OK, I've increased the drag coefficient from 0.30 to 0.40 (let's pretend that the car is in its Le Mans, low-drag aerodynamic configuration) and compensated, at least in part, by a reduction in frontal area from 2 to 1.7, which makes the top speed a bit harder to achieve but still doable.

I've been turning at 2'44" in Spa2008, while still learning the circuit.
EDIT: I had been using the original brake distribution 61/39 despite what was discussed here:

At La Source, it could even help you turn faster if done right. But I've realised that if you push the limit when braking downhill in the approach to Bruxelles, formerly Rivage, most of the time you will lose the back of your car and there is simply no human way to control it. Now I've uploaded a new file with 62/38 bias.
