- 28-32 PSI on Race tires
- On track temps near 32-33 psi
- Lower pressure = smoother loss of grip
- Lower Front/Higher Rear = Oversteer
- Higher Front/Lower Rear = Understeer
Drop front a notch to correct understeer for specific tracks
Longer gears needed for tracks with long straights, especially if you are pegging out your last gear on the straights Tweak final drive if shifting is awkward for corners on a track
Base Camber:
- RWD = -1.6 F, -1.3 R
- FWD = -1.3 F, -1.6 R
- AWD = -1.4 F, -1.4 R
- Higher = More corner grip, less straight line grip
- Lower = More stability, understeer
- Keep outside tires in the negative
- If they never go below -1, you can decrease it
Raise caster for more mid-corner front camber
- Caster range: 5-7
- Higher = more front camber in corners, stability, strong 'self centering' feel
- Lower = more 'lively' steering on straights/exits
Feel > Numbers - telemetry is a tool, not a rule.
- Front toe is usually adjusted out, rear in
- Never more than .5 degrees in either direction
- Out = Turn in / rotation
- In = Stability
- Start with even front/rear
- Base 40F, 40R
- Higher = Responsiveness, less body roll
- Lower = Smooth response, more body roll
- Lower Front/Higher rear = Oversteer
- Higher Front/Lower rear = Understeer
- Extremes can work. 1/40 for AWD & 40/1 for RWD may be viable
- Good ARBs allow for good rotation/transitions within control.
- You don't want it to snap and cause oversteer.
Base: Stock, or 50/50
Range: Varies, 20-60% is a good zone to stay within
- Higher = Responsive, stiff overall feel, more "twitchy"
- Lower = Smooth, softer overall feel, more body roll
- Lower Front/Higher Rear = Oversteer
- Higher Front/Lower Rear = Understeer
Base: 2-3 notches above minimum
Range: as low as possible
- Higher = More body roll and suspension travel, better on kerbs
- Lower = Improved center of gravity, grip and stability on smooth track
- Base: 4-4 Bump, 11-11 Rebound
- Range: 2-4 Bump, 9-13 Rebound
- Bump = compression rate, lower gives more grip
- Rebound = extension rate, higher gives more grip
- Find the lowest bump and highest rebount that still allows for stable kerbs, use F/R balance to dial in corner feel
- Lowering bump into the 2's will give more grip but can upset the car when going over bumps/kerbs
- Higher rebound will give more grip, but can upset the car when going over bumps/kerbs
- Rebound can often be maxed
- Bump should be raised first if you run into issues on kerbs/bumps
Base: Stock, neutral
- Higher = Less suspension movement, less force on springs
- Lower = More forces applied to springs, more weight transfer
Very powerful - make sure spring stiffness is set well before adjusting this
Affects how car feels during heavy acceleration and braking
- Low anti-dive - front of car dives on braking,
- High anti-dive = car stays level on braking, providing more stability and understeer
- Low anti-squat = Stable rear during exit
- High anti-squat = Active rear during exit
- Dive: Higher = understeer
- Squat: Higher = oversteer
Fine tune corner entry and exit feel with these settings
Base: Max front, rear should be based on power/drivetrain
Range: Rear varies, front should always be high
- Higher = More grip at speed
- Lower = Less drag
- FWD can usually run minimum rear
- RWD will usually be higher in the rear
Too high of downforce can lock the car down causing understeer
Base: Stock, 50%
Range: 70-40%
- Front bias: understeer while braking
- Rear biar: oversteer while braking
- Find a comfortable balance for corner entries
- Don't make big adjustments - a single percentage can provide a big impact.
- If struggling to keep the car straight and controllable while braking adding a little front bias can help
- If you want more rotation while braking move bias to rear by a couple of points
Base: 100%
Range: 100-200% (never below 100%)
- Higher = Faster, harder braking response
- Lower = Smoother braking response
- Higher settings mean the brakes will hit full pressure sooner, meaning they will also lock up sooner.
- Find highest setting you are comfortable with, make sure you can still lightly apply the brakes
Accel range:
- 90-100 for FWD or front diff on AWD
- 50-90 for RWD
Decel range: 0-25
Center range (AWD): 50-80
- High accel: Oversteer
- High decel: Understeer
- High decel prevents rear from rotating
- Low decel allows rear to rotate freely
Find the highest accel setting you can run while maintaining grip and control
