2. Lift and drop the suspension arms so that they settle in their lowest positions.
3. Using the droop gauge, measure the downstop value from the bottom of the front steering
blocks / rear uprights..
FRONT DOWNSTOPS
Measure at the bottom of the steering block. Do NOT measure under the arm.
Front Downstops
Higher front
downstop value
• Decreases front chassis upward travel on-throttle.
• Increases high-speed steering.
• Increases “initial” on-throttle understeer.
• Better on smooth tracks.
Lower front
downstop value
• Increases upward chassis travel on-throttle.
• Decreases high-speed steering.
• Decreases “initial” on-throttle understeer.
• Better on bumpy tracks.
Rear Downstops
Higher rear
downstop value
• Decreases rear chassis upward travel off-throttle or under braking.
• Increases stability under braking.
• Better on smooth tracks.
Lower rear
downstop value
• Increases rear chassis upward travel off-throttle or under braking.
• Increases steering in slow corners.
• Better on bumpy tracks.
1. Place the droop gauge support
blocks on the setup board, and
then place the chassis on the
support blocks.
Make sure the chassis is solidly
mounted on the support blocks so it
does not move.
DOWNSTOPS
INITIAL STEPS
SET-UP COMPONENTS:
Prepare the car as follows:
Use the following set-up components:
• Shocks: Detach the shocks.
• Anti-roll bars: Detach the anti-roll bars.
• Wheels: Remove the wheels.
• Droop Gauge Support Blocks
• Droop Gauge
