From what I saw with an FTO, a top speed setup for FWD would be:
Ride height: min/max
Spring rate: max/max
Extension: meh/meh
Compression: meh/meh
Anti-Roll: meh/meh
Camber: 0.0/0.0 (or so)
Toe: 0.00/0.00
Gearing should simply be adjusted until you're at peak power RPM in your highest gear when the car absolutely stops accelerating.
