Well done in finally winning it!
Do you use a wheel or controller? TCS?
I have all aids off except driving line and ABS on 1. I set up the brakes as Ft9/Rr10 and slide into sharper corners under very late braking! I can't do that with skid recovery on, but if i'm using a controller, then i need skid recovery. I never use TCS anymore!
Also, why would you use it stock??
Increasing the strength of the brakes allows you to brake later, giving you a massive advantage.
And why not adjust the top end speed according to the track??
If you're hardly getting into top gear (7th), then you're costing yourself much-needed acceleration...
On the flip-side, if you're red-lining at top speed on a long straight for several seconds, you're costing yourself more speed...
If you were already struggling, why would you make it harder than it needs it be?! Forgive me if that doesn't make sense to me.
