Bad part was the front would hop and wiggle like crazy when being pushed hard in the corners. I had to keep changing the set up to get rid of the front end chatter.

The set up that worked best was:
Front
Shimizu grooved soft
3* caster/2* camber/zero toe
.018" springs
ride height 5mm
7mm wheel hexes for more track width

Rear
Shimizu grooved soft
2* camber/1* toe
stock FGX springs/oil with 3 o-rings used as a bump stop to keep the chassis from bottoming in the corners (really want to just get stiffer springs whenever they are available)
Added 1mm shim to the ball end that the shock connects to for more leverage over the suspension (also to make the spring seem stiffer)
6mm ride height.

Car was very fast with this set up. Got second to a F104W. Reeling him the last minute of the race, only 0.2 second behind at the buzzer. I could have won if I had one more lap!
