Instead of paying someone credits try this for a decent enough ballpark setting. It's not perfect, not by a long shot, but it'll be a decent enough place to start and tweak from. Or leave as is.
Front and rear camber at about -0.7
Front and rear toe at 0.4 (Positive toe)
Leave Caster alone.
Front anti-roll bar about half of the rear anti-roll bar. Set the level according to what you like. (My preferred is 7.40/14.80)
Spring rate: Harder rear spring than front. Go towards the high end of things. (My settings are 155 / 166 . No need to match exactly)
Ride height: Drop the nose. Tail up, nose down. (12.8/13.7)
Front rebound stiffness should be a little greater than rear. Keep them both towards the high end of the bar. (10.4/9.4)
Front bump stiffness should be smaller than rear. Keep them bump stiffness below a third of rebound. (2.5/4.1)
Front Accel: <25 (I'm at 16)
Front Brake: 0
Rear Accel: 60-75 (69)
Rear Brake: 20-30 (24)
Centre: 50-70, according to taste. (60)
Forward at full.
Rear at half.
That should make for something pretty tail happy, but pointy too. A
Parts, off the top of my head for A class.
Race brakes, suspension, roll-bars, roll-cage, race weight reduction
Race Differential. Race Gearbox (Shorten 1st gear!). Race driveline.
Add front and rear downforce option.
Race tyres. Put the widest tyres on front and rear.
Use the lightest wheels.
The only engine upgrade I've used is to fit a sports exhaust.
Or I could just gift you a copy of mine since it's a pretty cheap car, and I've got full Nissan affinity.
