Ride height: depends on bumps, lower is better some where around 10mm, a little track scuffing is acceptable for me as we have a high speed cross town with bumps.
Droop: A little more in the rear, 10-15mm. Absolutely left same as right side.
Camber: 2 1/2f and 2r degrees
Pinion: On our track you need to go 50-55mph on the straight(~220'), with 2650/4s and high speed diff gears(3.31) a 19-20t pinion/42 spur is needed. Fast lap times for us are in the 21-22 second bracket.
Shock position: middle top and outboard bottom.

These cars are laying down the fastest laps on our track ever for GT8. They're not far behind the 1/10 mod sedans. Not bad for ~8.5lb car.
