Here is a setup I have been running lately, it changed from what I posted a while ago. Mainly I went to Losi shock pistons and it made a huge difference. This feels like it would work on a variety of tracks, but I haven't had a chance to try yet.

Front:

Shocks inside tower-middle arm
Silver Associated springs
#56 Losi pistons
35 wt losi oil
0 limiting
Associated shock shafts
Camber link inside/top on tower - standard ballstud on carrier 0 washers
Carriers up (pin in bottom hole on carrier)
Carriers shimmed forward
0° toe
-1.5° camber
Diff set pretty loose
Ride height arms level

Rear:

Shocks second hole from inside on tower - inside/bottom arm
Green Associated springs
#55 Losi pistons
35wt losi oil
.138 limiting (associated shock shafts are longer 46.9mm)
Standard shock tower
Camber link middle hole on camber plate - middle hole on hub 2 .030 washers
1° hubs
Hubs forward
Arms back
0° anti-squat shims
3° rear pivot pointing up
-1.5° camber
Rear diff fairly loose
Ride height bones slightly above level

Drive train:

Trinity 10x1 Shock
16x84 gearing
center one way about 75 locked
belts set fairly loose where they occasionally skip.

CRCRC in Columbus Ohio. This is an indoor track that is usually fairly smooth. The surface is a clay/topsoil mix that is tamped very firm. Traction varies from high bite, to medium bite, sometimes it gets dusty and loose when it's too cold to water.

Pink Losi taper pins at all times.

I did run the car at our big race in Jan and I had to go up to blue AE springs in the front and silver AE springs in the rear, and I ran a rear sway bar. At that track we ran slick pink taper pins and there was TONS of traction.
