Here are my basic setup for 13.5t stock and 6,5t Open timing modified classes.

In a nutshell:

• add 2x 0,5mm shims to kingpin for less droop, i recommend doing this to start with.
• Shock is 66mm (max length to end of ball cups), the other ball cup is shortened a bit.
• 600cst shock oil
• Kyosho 5k diff grease on kingpins for damping
• 30k diff oil for rear damper
• Polished kingpins!
