Finally, finally made it (on the private drive!!)
Flat, with a slight kink and a very slight uphill end bit.

How did I achieve it?
Today lost 63.4 kg out of the back of the car (seat backs, bench, trim, spare wheel and sub box)
Octane booster and B7T7F7 settings.
1/4 tank of fuel left.
Launch control at 2.2k with R888's onboard.
So that is one of my goals achieved, now all I need is a sub 13 second run on an official dragstrip and a sub 9 minute FULL lap of the 'ring and I'll be one majorly happy bunny.

Time to change the sig. maybe
