With Bird's setup, I could do a 2:01.891. But with Marty's setup, I got to a 2:00.671. I made a few further tweaks to Marty's - just moved the brake bias more rearward as I was locking up too much, to 67, and also lowered the front/rear rollbars to 0/3 to reduce the temp difference left and right. This got me down to 2:00.214, about 1.2 seconds off my PB.
