Ouch. WGI isn't forgiving...
I did a 2:15 something on heat cycled out BFGs on stock motor and brakes with pads and fluid (before they gave up on me), and I doubt that I am the faster driver although I ain't slow, so you probably have 3-4 more seconds in you if you weren't so concerned about going back to Canada in one piece.
I'll say that you can be more aggresive with the curbs into and out of 1 and into and through the bus stop. You sure you have your foot planted through the esses?
