@UKD: There are some tricks to get round a corner and tune your car right for the mouse.
Like brake-bias, put it about 80% in front, the front wheels will block when you brake. May not look pretty but since we cant have 60 or 70% braking with pedal our car destablizes very easy, if the brake-bias is 50% you will spin guaranteed.
You need to remember with each corner how many meters from the corner you brake (like 53) So at 53 you can brake 100% and go through the corner in the inner side.
The gear-ratio to 4.5. This makes shorter gears so you can go through corners in 3rd gear, and if you are going to fast you can go to 2nd and the car will slow down even more on the engine, which may prevent you from crashing.
A thing that I thought was good, was braking on the engine, if you push the brake for about 5 seconds the revs are going to idle and the car will become unstable.
With the mouse you should throttle a little bit after every gearchange, try some things with that. not sure if I explained it clearly right now.
If you come out of a corner, don't counter-steer too much, that will cause you to drifte. Hold the "wheel" straight and the car will drift slightly and you're out of the corner at full speed.
Don't rev into the redline too often, the engine can break. So if you do it a lot to brake on the engine, you're slower at the end.
