SHOCK SETTINGS

Front Shock Position:

Moving the top of the shocks in will make the suspension softer, slow steering response, and

make the car smoother through the bumps. Moving the top of the shocks out will make the

suspension stiffer, increase steering response, and make the car react quicker. The standard

location (center hole on the tower) works well for most tracks.

The bottom of the shocks can also be moved on the suspension arms. Moving the bottom of the

shocks to the inside holes on the arms will result in more low-speed steering and less high-speed

steering. Mounting the shocks to the inside hole will require limiters inside the shocks to limit the

travel. The springs should also be replaced with stiffer ones.

Rear Shock Position:

Moving the top of the shocks in will make the suspension softer, increase side-bite (traction in

corners), and make the car smoother through the bumps. Moving the top of the shocks out will

make the suspension stiffer, increase forward traction, and help keep the car from bottoming out

on big jumps. The standard location (center hole on the tower) works well for most tracks.

Moving the bottom of the shocks to the outside holes on the rear suspension arms is not

recommended.

Front Damping:

Shock oil changes can dramatically affect steering and handling characteristics. In general,

lighter oil will increase steering response, increase low-speed steering, and make the car handle

small bumps better. Heavier oil will increase high-speed steering and make the car handle large

jumps better. Changing oil to far in either direction can have the opposite of the desired effect, so

make changes in reasonable increments.

Damping can also be adjusted by changing shock pistons. The kit includes Associated #1, #2,

and #3 pistons. The higher the number, the smaller the holes in the piston. Smaller holes create

more damping with the same weight oil.

Rear Damping:

Shock oil changes can dramatically affect steering and handling characteristics. In general,

lighter oil will increase rear traction and make the car handle small bumps better. Heavier oil will

slow front to rear weight transfer, resulting in more high-speed steering and better landings off

large jumps. Changing oil to far in either direction can have the opposite of the desired effect, so

make changes in reasonable increments.

Damping can also be adjusted by changing shock pistons, as described above.

Springs:

Increasing spring rates generally tens to increase steering response and make the car react

quicker. However, stiffer springs tend to make the car more erratic through the bumps.

Decreasing spring rates tends to slow steering response and make the car smoother through the

bumps. It is necessary re-check the ride height after any spring adjustment.
