  • If you aren't hitting any cones, try harder.

0.815-0.816 is my guess as well.

The SSC car is essentially a CS FR-S car minus 10lbft of torque, and plus 0.5" of wheel and 0.5 degrees of camber. I was being pessimistic with my guess... I think it'll be better than a CS ND Miata... but don't think it'll be better than a good BS car.

Your argument is (somewhat) convincing, so I ended up voting for .814
The (somewhat) is because that camber allows much more effective use of that extra wheel width.  And effective usage of your rubber trumps so many things.

We're missing one key piece of information, which is what the spec tire will be. If it's anything other than the RE-71R, Rival S, or Nexen, SSC could end up slower than CS.

A BS Vette has about as much camber as it wants doesn't it? And a lot more tire and thrust versus mass.

The Tire Rack friendly wheel offset regulations look like they are going to limit SSC cars to about 2.5 degrees front camber.  STX twins run more than three, so one has to wonder if 2.5 will be enough.  In the rear, street regulations give twins adequate camber.

Regardless of where PAX ends up, I'm locked in, and excited about the idea of some local competition outside of the index.

Yeah, we shouldn't let this devolve into a discussion over PAX "accuracy" :)

Exactly, because nothing trumps my HS pax anyway :P well, except for maybe perhaps sometimes better drivers than me ;D
