Here's a set-up that always worked well for those type of classes on a Nemesis:
Nose: 45.5%
Left: 54.0%
Cross: 68.0%
LF: Camber: +0.5 / Caster: 8
RF: Camber: -3.25 / Caster: 12
Stagger: Front: 1.375" / Rear: 0.75-1.25" (determined by track size/corner radius)
Rear track width: 39.25"
However, with a little more power on a clone and the tires making more bite than what they used to, you can probably run a little bit more left side percentage.
Good luck!
