The advantage points on track are anywhere with top speed (it WILL have higher exit speed given "all things equal") and really, any turn that cannot be taken at wide open throttle.
Like I said in my comparison to danoff... I blew the chicane, nailed the hairpin, fairly good on sweeper (though not AS good as it could have been) nailed the left after T2 (also the first of the 'quicks' (left-right-left) and in the final turn where the RGT will have more power oversteer, which is the trick to getting from T3 to the finish so quick.
For the first turn, the RGT owns everything (non race bodied at least) even when I really nailed it with the 3400s I couldn't compare to the speed the RGT was capable of through it. 120+ mph is possible, which is just absurd. And even then, the sector time you compare to was a "slow" one for me, as I made the turn at 116 minimum, 4 less than "normal."
(sector 4) was slow (frrm me) due to a ****e chicane section. Were you ever able to get through the chicane OVER 90 mph? I did on several occaisions, and that is cleanly too.
As for the hairpin, that haripin requires early braking so that you can catch the rumble and the car turns itself. I would suspect similar results between the cars, with the RGT edging out a slightly better time.
For the sweeper, I would imagine that any of the cars should be relatively equal there, you just have to learn how to ride the rumble strip without being pulled onto the sand trap, or without being slingshotted off before you intended (like near the end).
The left immediately after the T2 mark would be owned by the RGT, at least I think so.
However, I do think that the 350 or 3400 would beat the rgt in the right-left after T2 leading to T3. The RGT just didn't want to take the final turn fast, it didn't matter what the line was, something would upset the car if going over 100 mph. I think there was ONCE (out of probably 200 time through that turn) that I managed 10x mph and didn't upset the car or slide too far outside on exit.
And like I said, the RGT would definitely take the cake through the final bit, as the power oversteer is much more pronounced and definitely the best way to take an 'increasing radius J-turn."
