I personally feel the Nemesis would put you a few tenths behind per lap to begin with. You must consider that chassis is essentially 10 years old. Just think of the improvements in chassis innovation in the past 10 years. You have to be on your A game in order to be competitive on any chassis that old.
As for a set-up, I'd like to start out with something like:
Nose: 45.5%
Left: 54.0%
Cross: 68.0%
Camber:
LF: +0.5
RF: -3.25
Caster:
LF: 8
RF: 12
Stagger:
Front: 1.25"
Rear: 0.75"
Rear track width: 39.0-39.25" (RR rim 1/8-3/16" from frame rail)
