Update:
27.706-45.775-65.707
20.645-38.659-58.312 OPEL.
I was a bit pessimistic in my original estimate, as I have improved by .6sec. and can see there is still a boat load left.
My first lap PB=27.376-45.115-64.642, with a lap time I haven't come within .7sec. I can't, for the life of me, recreate it.
My current save is my second lap PB with an OK first lap.
Same as it ever was. It's a good first then a hohum second or it's the other way 'round.
It has been my experience, that the race with the Mercedes in 5th position, offers the least impediment by the AI. There are, I think, two. But, the one I am referring to has the Opel on pole, followed by the Raybrig NSX, Tickford Falcon, Mugen NSX, Mercedes and you. Get up behind the Mercedes and squeeze between it and the wall, this allows a free run up the inside to turn2, where you can block the AI or clear them completely. On the approach to turn2 the Tickford will be behind the Opel, the leading Raybrig will be taking a late apex and will come down on you, so watch out for it. Brake when you are up to the Tickford's rear bumper and downshift to 2nd or 3rd gear.
If the AI are giving you trouble, try it.
