It's funny, i never raced a 22B till i got to GT4...matter of fact i was just racing my 22B last nite.
I never tried it in GT3 but you can try using the settings i used in 4. These aren't heavily exact, and i was only using a semi-racing suspension at best but here goes:
Springs: 5.0 ish [F] 4.0 ish [R]
Dampers: 4/8
Ride height: 116/123
Camber: 3.0 / 1.8 degrees
Racing brakes (but no controller--you can buy one and experiment tho).
medium sports front, hard sports rear.
No limited slip
No stability or traction controls
Obviously since i was using a semi-racing suspension, there's no toe or any of the more advanced stuff. Also keep in mind that in gT4 it's hard to get cars to oversteer, hence the way i have my tires equipped (medium/hard) may be a disaster in gT3!
