Camber is one of the most critical adjustments in suspension setup, especially in the high-stakes world of Formula Drift. This seemingly small angle—defined as the tilt of the wheels in relation to the vertical axis of the car—has a profound impact on grip, tire wear, and cornering performance.
In Formula Drift, camber settings vary widely depending on the car’s design, wheel and tire setup, and the driver’s style. Let’s dive deep into how camber works, its benefits, and what settings professionals likely run on their drift machines.
Understanding Camber
What is Camber?
- Negative Camber: The top of the wheel tilts inward toward the chassis. This improves cornering grip by ensuring more tire contact during lateral loads.
- Positive Camber: The top of the wheel tilts outward. Rarely used in performance applications, it is more common in vehicles designed for off-road stability.
In drifting, negative camber is king, as it optimizes grip on the front wheels while sliding through corners at extreme angles.
Why is Camber Important in Formula Drift?
-
Maximizing Grip
- Negative camber ensures that the tire maintains maximum contact with the road when cornering.
- For the front wheels, this improves steering precision and allows for sharper turn-in.
- For the rear wheels, slight negative camber can improve stability during transitions.
-
Tire Wear Management
- Excessive camber (positive or negative) can lead to uneven tire wear.
- Formula Drift teams carefully balance camber settings to maximize performance while minimizing the need for frequent tire changes during competition.
-
Optimizing Suspension Geometry
- Camber settings interact with other suspension adjustments, such as caster and toe, to create a cohesive handling package.
Camber Settings and Variables in Formula Drift
1. Car Type
Different cars have unique suspension designs that influence how camber is adjusted and how much is optimal.
- MacPherson Strut (e.g., Toyota Supra): Typically limited in how much camber adjustment is available without aftermarket upgrades.
- Double Wishbone (e.g., Nissan S-Chassis): Allows for greater camber adjustment and fine-tuning.
2. Wheel and Tire Size
The interaction between camber and wheel/tire dimensions is significant:
- Wider Tires: Require less camber to achieve the same contact patch under load.
- Smaller Wheel Diameters: May necessitate different camber settings to avoid contact with suspension components.
- Formula Drift Standard: Many competitors run wide, low-profile tires (e.g., 275–315 mm widths) on large-diameter wheels (18–19 inches), which influences their camber requirements.
3. Front vs. Rear Camber
- Front Camber: Often set aggressively negative (e.g., -4 to -6 degrees) to maximize grip during steering at high angles.
- Rear Camber: Typically less aggressive (e.g., -1 to -2 degrees) to maintain stability and even power delivery during drifts.
The Benefits of Negative and Positive Camber
Negative Camber
- Increased Cornering Grip: Keeps the tire’s inner edge planted during lateral loads.
- Sharper Turn-In: Ideal for the aggressive steering angles used in drifting.
- Improved Predictability: Helps drivers maintain control during transitions.
Positive Camber
While rarely used in Formula Drift, slight positive camber might be found in unique applications:
- Off-Road Stability: Positive camber can improve straight-line stability on uneven surfaces.
- Specialized Drift Setups: Rare cases where unique car dynamics or driver preferences come into play.
How to Adjust Camber
1. Camber Plates
Camber plates are mounted at the top of the suspension strut and allow for precise adjustments.
- Adjustability: Typically offers a range of negative and positive camber adjustments.
- Aftermarket Options: Essential for cars like the BMW E36 or E46, where stock adjustability is limited.
2. Adjustable Control Arms
For rear camber, adjustable control arms are a popular solution, especially in multi-link suspensions.
- Fine-Tuning: Allows adjustments to align the rear tires perfectly for optimal drift balance.
3. Slotting Suspension Mounts
An older method involves elongating the mounting holes in the suspension components to enable limited camber adjustments.
What Camber Settings Do Formula Drift Pros Use?
While settings vary between drivers and cars, here’s a general idea of what the pros might run:
- Front Camber: -4 to -6 degrees. Aggressive negative camber for maximum grip and steering control.
- Rear Camber: -1 to -2 degrees. Less aggressive to maintain stability and reduce rear tire wear.
Examples
- Chelsea DeNofa and Adam LZ (BMW E46/E36): Typically run aggressive front camber to complement their high-angle SLRspeed angle kit.
- Chris Forsberg (Nissan 370Z): With a double-wishbone setup, his car allows for precise camber adjustments tailored to each track.
Camber and Weight Transfer in Drifting
Drifting requires mastery of weight transfer, and camber plays a pivotal role:
- Entering a Drift: Negative camber on the front wheels ensures grip as the car shifts laterally.
- Mid-Drift: Proper camber settings prevent the tires from rolling over onto their sidewalls, maintaining consistent grip.
- Exiting a Drift: Balanced camber across all four wheels aids in regaining traction smoothly.
