Here at Stone Motorsport, we are passionate about Drifting and equipping drivers with the knowledge and tools to excel on the track. A well-prepared drift car isn’t just about raw power; it’s about balance, precision, and the right setup. In this comprehensive guide, we’ll walk you through the key elements of preparing a drift chassis, helping you achieve optimal control and performance.
Before diving into the technical aspects of setting up a drift car, let’s clear up a few misconceptions about drifting. As someone deeply involved in motorsport, I’ve seen these myths far too often, and it’s time to set the record straight:
1. Grip is King, Even in Drifting
Contrary to popular belief, drift cars aim to maximize grip on both the front and rear tires. The idea is to generate enough traction to maintain high speeds while holding a controlled drift. Of course, more grip means more power is required to overcome it.
2. Drifting is a Real Motorsport
Drifting isn’t just about showmanship—it’s a legitimate motorsport. It involves cars, engines, drivers, and clear winners and losers. Judges evaluate every detail, from precision and proximity to fluidity and style.
3. Top-Level Drift Cars Are Purpose-Built Machines
At the highest levels, drift cars are custom-built for performance. These aren’t modified road cars anymore—they’re powerful, finely-tuned motorsport machines designed specifically for the demands of drifting.
Now that we’ve addressed the myths, let’s talk about what drifting is: a motorsport where drivers maintain fluid oversteer through a series of corners, hitting clipping zones and maintaining proximity to an opponent. A well-prepared car is crucial for success, and that begins with the setup.
Coilovers: Invest in adjustable coilovers to fine-tune ride height, stiffness, and damping. Lowering the center of gravity improves handling, while custom settings allow you to adapt to different track conditions.
Sway Bars: Stiffen the sway bars to reduce body roll and maintain balance through corners. Upgraded sway bars help the car respond predictably during transitions.
Bushings: Replace stock rubber bushings with polyurethane or solid bushings for sharper and more consistent suspension geometry.
Suspension Setup: The Foundation of Control
A properly tuned suspension is crucial for maintaining stability and maximising grip during high-angle slides.
Here’s what to focus on:
1. Camber: Precision at the Front and Rear
In drifting, camber plays a vital role in maintaining control and grip:
• Front Camber: Drift cars often feature negative camber ranging from -4° to -7°. This ensures that the lead wheel achieves zero camber at three-quarters lock, maximizing grip during turns and reducing understeer.
• Rear Camber: For the rear, a slight positive camber (e.g., +0.5°) is common. Soft setups, combined with power squat, ensure maximum tire contact under load. Testing and adjusting camber based on tire wear can fine-tune performance.
2. Caster: Self-Centering Magic
Caster angle is essential for helping the steering wheel self-center during transitions. Higher caster (5°–12°) allows the driver to rely on the car’s natural geometry to steer through corners. This setup lets drivers “steer from the rear,” a hallmark of competitive drifting.
3. Toe: Balance Grip and Precision
• Front Toe: Personal preference rules here—some drivers prefer neutral toe (0mm), while others favor slight toe-out (up to 2mm overall) for sharper turn-in.
• Rear Toe: Toe-in at the rear improves grip and stability. For most builds, 0.5mm–2mm per wheel is sufficient. High-powered cars may use more aggressive toe-in, but excessive settings can strain drivetrain components.
4. Anti-Roll Bars: Tuning Oversteer
Drift cars differ significantly from circuit racers in their use of anti-roll bars:
• Front Anti-Roll Bar: Often removed to enhance front-end grip and allow the rear to pivot more easily.
• Rear Anti-Roll Bar: Useful for lower-powered cars to improve transitions and oversteer. For high-powered setups, removing it softens the rear for better traction.
5. Spring Rates: Softer is Better
Competitive drift cars use surprisingly soft spring rates (e.g., 10–12kg/mm front, 8–10kg/mm rear). This softness enhances grip, allows the tires to maintain contact with the track, and absorbs bumps effectively.
6. Roll Centers: Fine-Tuning Balance
Adjusting roll centers can optimize the balance of stiffness and grip. For a starting point:
• Front Roll Center: 30% of the car’s center of gravity (COG) height.
• Rear Roll Center: 15% of COG height.
This creates a balanced setup that’s easy to tweak based on driver feedback.
7. Bump Steer: Eliminate It
In drifting, bump steer must be eliminated at both the front and rear. However, adjustments should be made with the wheels at the average lock angle rather than straight ahead, as drift cars spend most of their time on lock.
8. Ackermann: Find Your Preference
Ackermann settings (positive, zero, or reverse) depend entirely on the driver’s style. Adjustable setups are best, allowing you to experiment and determine what feels right for you.
Building the Ultimate Drift Car
When designing a drift car, several key principles come into play:
1. Center of Gravity (COG): Lowering and centralizing the COG improves balance and handling. Mounting heavy components like the radiator and fuel cell at the rear can offset front-heavy setups.
2. Wheel Travel: Ensure sufficient wheel travel to accommodate bumps and maintain tire contact. Modifications like trimming wheel arches and extending brake lines may be required.
3. Lock Kits: Kits from brands like Wisefab provide wider track widths, increased steering angle, and adjustable geometry. These kits are essential for competitive drifting, allowing precise control and extreme angles.
4. Rear Suspension: Upgraded rear suspension arms eliminate undesirable traits like camber gain and bump steer, while correcting roll center positions for optimal performance.
Steering Modifications: Maximise Your Angle
Steering is at the heart of drifting, and modifications can significantly enhance your ability to maintain control:
• Angle Kits: Install angle kits to increase steering lock, allowing for sharper drift angles without sacrificing control.
• Rack Spacers: These simple upgrades increase steering angle by pushing the tie rods further out, giving you more flexibility in tight corners.
• Power Steering Upgrades: Ensure your power steering system can handle the increased stress of drifting with high-angle setups.
3. Tires and Alignment: Traction Where It Matters
Drifting is as much about controlled sliding as it is about maintaining grip in the right moments. Proper tires and alignment settings make all the difference:
• Tires: Use performance tires with predictable grip. For the rear, prioritize tires that can handle high wear but break traction smoothly. In the front, use grippy tires for precise steering.
• Alignment:
• Front: Add negative camber for sharper turn-in response and toe-out for quicker steering.
• Rear: Adjust camber and toe-in to maintain stability during transitions.
4. Braking System: Precision in the Slides
A strong and responsive braking system is essential for initiating and controlling drifts:
• Hydraulic Handbrake: A hydraulic handbrake gives you the ability to lock the rear wheels instantly, making drift initiation smoother.
• Brake Bias Adjustment: Adjust the brake bias to ensure the rear brakes activate more aggressively without compromising overall stopping power.
• Upgraded Pads and Rotors: Invest in high-performance brake pads and rotors to handle the increased heat and stress from drifting.
5. Weight Balance: The Key to Fluid Motion
Weight distribution directly affects a car’s handling and drift dynamics. Aim for a 50/50 balance between the front and rear:
• Relocate Components: Move the battery to the trunk or lighten the front end to achieve better balance.
• Lightweight Components: Replace heavy stock parts with lightweight alternatives, such as carbon fiber panels or aluminum components.
6. Essential Safety Upgrades
Safety should never be compromised, whether you’re practicing or competing:
• Roll Cage: A roll cage adds structural rigidity and protects you in the event of a crash.
• Racing Harness: Keep yourself securely in place during high-G-force slides.
• Fire Suppression System: Ensure your car is equipped with fire safety measures to protect against unforeseen incidents.
7. Test, Tune, and Refine
Drift car preparation doesn’t end after installation. Regular testing and tuning are crucial for continued improvement:
• Track Days: Take your car to practice sessions to test its setup under real-world conditions.
• Telemetry: Use telemetry tools to measure performance and identify areas for refinement.
• Driver Feedback: Adjust settings based on how the car feels during practice—drifting is as much an art as it is a science.
