with the Nismo 34r mod (the best one to use) I have laid down a 2:08.151 at bathurst.
a 2:07 definitely possible as I'm still tweaking suspension settings and have only done 10 laps in the car so far.
Tips...
1, soften suspension
2, change gear ratios till you can get 308KMh down conrod with rear wing on 2 and front splitter on 2
3, MUST increase brake ducts to as big as you can. Brake fade is a MAJOR problem with brake temps over 1100degrees!!! brake at the kink in the end of conrod, and pump the brakes, brake earlier here, because by the final turn, the brakes don't get enough time to cool and you can end up in the fence with no brakes!
4, use torque split of 35 front 65 rear. or 30/70
5, increase tyre pressures and play with camber settings till you have even tyre temps across the tyres. cold in the middle, add pressure and vice versa.
6, slow in, fast out
7, drive smooth, smooth is fast, don't try to drift, it will, but don't try!
8, raise rev limit to 9000RPM
hope that helps, and gives you something to aim for!
