Advice: New Alignment specs
So after talking with a few peeps, these will be my next alignment specs:

So I will set the new alignment for:

997S
JRZ RS Pro Suspension (650/850) Spring Rates
Toyo R888/RA1 Tires

Specs:

Front: -3.0º
Toe Out: 2 mm (1&1)

Rear: -3.3º
Toe Out: 4mm


AGGRESSIVE!!!! ARRRRRR


What do you think?

That much toe out in the rear of an early susp car would be a real handfull. I run a touch of toe in the back and about 1 mm of toe out in front. I am not strong on late susp car setup but are you sure is is 4 mm toe out in back?

Like Kurt alluded too, it should be toe-in in the back. 2mm toe-in per side would be a good starting point. I would also recommend less camber in the back. The new cars have really good rear suspensions with lots of roll camber compensation. I would back it down to between -2.3 to -2.5 max. I tried -3.3 on my 6GT3 and it tore up tires and overheated in inside edges.

More spring if it's full track car. .............

I completely agree with Larry, particularly wrt the rear camber. You will chew up the inside edges of R888's with that much camber. Car will push until the inside edges of the rear tires wear out (which will happen soon with that kind of camber), and then be loose as all get out.
