My Tc3 setup as it stands. I know my car has one off parts, but this takes that into account and should get ya close.
FRONT
-------
Shocks: Oil, 50wt. Springs, HPI Silver (6825). Piston, #1. For standard shock towers/arms use the inside hole on both for shock position.
Steering knuckle: Tc4. Ouside hole.
Caster: 4 degrees
Camber link: Silver ballstud in both locations. Add .030 washer under inboard ballstud. Inboard ballstud in the innermost position.
Steering rack: Silver ballstud and .030 washer.
Bumpsteer: Make steering link parallel to the suspension arm at static rideheight.
Diff: Slipper spool.
Suspension mounts: F+0 and F
Ride height: 5mm for this setup.
REAR
------
Shocks: Oil, 40wt. Springs, HPI Pink (6849). Piston, #1. For standard shock towers/arms use the outside hole on both for shock position.
Rear hub: Losi. 0 offset/toe.
Camber link: Silver ballstud in both locations. Add .030 washer under inboard and outboard ballstuds. Inner position on hub, and one out from inner position on 'wing'.
Wheelbase: Rear hub forward.
Diff: Plastic outdrives.
Suspension mounts: F and R+3+2
Ride height: 5mm for this setup.
Tires: Usually Sorex 36's because of the heat, medium inserts. The car seems to like a tire on the cooler side of its heat range, so if the asphalt is 110 degrees, dont hesitate to try Sorex 40's. You will get more steering, and more response from the car by doing so.
I also noticed the car lost its response if it sat on the track baking in the sun. I was on the stand working on radio adjustments, and randomly talking to people while the car sat in the sun for over 20 mins. I took it inside for an hour to let the battery charge, made no changes, took it back out and the car was responsive again. It seems the extreme heat softens the tub somewhat.
General
---------
No swaybars. No droop screws. No internal shock springs. Battery is an SMC 4500mah pack, forward position. I run boosted 17.5 and use an 81t 64p spur to find my ratio. Try to find your ratio with the smallest spur possible for best motor placement/chassis balance.
This setup will wash out if you blast into sweepers without maintaining your speed to hold your line. It works best on medium to tight courses with good throttle control.
