FH6 Suspension Tuning Guide
Suspension tuning is the most impactful adjustment you can make to a car's handling. This guide covers every parameter and how to tune for your driving style.
Spring Rates
Spring rate controls how stiff the suspension is.
| Setting | Effect | Best For |
|---|---|---|
| Soft springs | More mechanical grip, body roll | Bumpy roads, off-road, comfort |
| Medium springs | Balanced grip and response | A class racing, daily driving |
| Stiff springs | Less body roll, sharper response | Smooth tracks, S1+ class racing |
Rule of thumb: Stiffer in the front reduces understeer. Stiffer in the rear reduces oversteer.
Baseline:
- Racing: Front 70%, Rear 65% (stiffer front → less understeer)
- Drift: Front 50%, Rear 85% (soft front + stiff rear = easier to rotate)
- Off-road: Front 40%, Rear 35% (soft = more compliance)
Damping (Bump & Rebound)
Damping controls how fast the suspension compresses (bump) and extends (rebound).
| Parameter | Stiffer | Softer |
|---|---|---|
| Bump (compression) | Less dive/squat, harsher ride | More compliance, absorbs bumps |
| Rebound (extension) | Slower extension, more stable | Quicker response, less control |
Baseline settings:
| Style | Bump Front | Bump Rear | Rebound Front | Rebound Rear |
|---|---|---|---|---|
| Circuit Racing | 5.0 | 4.0 | 8.0 | 7.0 |
| Street Racing | 4.0 | 3.5 | 6.0 | 5.5 |
| Drifting | 2.0 | 1.0 | 4.0 | 3.0 |
| Off-road | 1.0 | 1.0 | 3.0 | 3.0 |
Camber
Camber is the vertical angle of the wheels — negative camber means the top of the wheel tilts inward.
| Setting | Effect | Best For |
|---|---|---|
| -0.5° to -1.0° | Minimal | Highway cruising, drag racing |
| -1.5° to -2.0° | Moderate | General racing, balanced handling |
| -2.5° to -3.5° | Aggressive | Drifting, track driving |
| -3.5°+ | Extreme | Max cornering grip (sacrifices straight-line) |
Baseline:
- Racing: Front -2.0°, Rear -1.5°
- Drift: Front -3.0°, Rear -1.0°
- Street: Front -1.5°, Rear -1.0°
Ride Height
| Setting | Effect |
|---|---|
| Lower | Lower center of gravity, better handling, risk of scraping |
| Higher | More suspension travel, better for off-road |
Baseline:
- Racing: Lowest possible without scraping
- Drift: Low front, slightly higher rear
- Off-road: Highest setting for clearance
Anti-Roll Bars
| Setting | Effect |
|---|---|
| Stiffer front | Less body roll, more understeer |
| Stiffer rear | More oversteer, helps rotation |
Baseline:
- Circuit: Stiff front, medium rear
- Drift: Soft front, stiff rear
- Street: Medium both

Tuning Process
- Start with the baseline for your driving style
- Drive 2-3 laps, note what the car does
- Adjust ONE parameter at a time
- Test again
- Repeat until satisfied
If the car understeers (won't turn):
- Soften front springs OR stiffen rear
- Increase front bump damping
- Increase front negative camber
If the car oversteers (spins out):
- Stiffen front springs
- Soften rear springs
- Decrease rear negative camber
- Stiffen rear anti-roll bar
