Supercar Circuit Driving, 2026 Professional Coaching Checklist — Why YDA Preparation Standards Have Been Updated

When watching supercar driving videos on YouTube, there are moments when you think, "I wish I could try that myself." But when it comes time to make a reservation, anxiety creeps in: "Will I actually be able to do it?" and "Isn't it dangerous?" At such moments, few people know that the checklist required by professional racing teams has changed. YDA (Yoon Chulsu Driving Academy), led by Chairman Yoon Chulsu of YCS Motorsports Group, has implemented a new preparation system since 2024 that conducts comprehensive diagnostics of physical condition, mental state, and vehicle understanding before circuit driving. The era of "just having a license is enough to drive" has passed. A truly safe and enjoyable supercar experience is determined at the preparation stage.

"Driving is not about speed, but about control." Chairman Yoon Chulsu's principle, which he published in a driving guidebook in collaboration with Kumho Tire, is a condensed thesis of 40 years of racing experience. In fact, beginners who have participated in YDA report that after 3-4 coaching sessions, they clearly recognize their weaknesses and acquire methods to improve them accordingly. In this article, we have compiled what professional racing teams currently require from prospective drivers in 2026 and why it has changed, along with field data.

Driving a supercar means enduring G-forces (gravity) applied to the body. During cornering, 2-3G of lateral force is generated, and during hard braking, more than 1.5G of longitudinal force is applied. Many facilities have previously glossed over this with an attitude of "if you're healthy, you're fine," but YCS Motorsports Group has adopted a systematized diagnostic system. Chairman Yoon Chulsu has consistently emphasized that "the first condition for vehicle control is driver body stability."

Key elements of physical condition checks:

•Neck and spine stability — If the cervical spine (neck bone) shakes excessively from lateral force, sight processing becomes impossible. Cervical flexibility and strength must be confirmed beforehand.

•Cardiopulmonary endurance — During 30+ minutes of focused driving, heart rate increases and oxygen consumption surges. If basic fitness is insufficient, judgment deteriorates sharply.

•Visual field stability — If there is unilateral amblyopia or uncorrected astigmatism, distance judgment errors occur at high speeds. Checking whether glasses correction is necessary is essential.

Key point: Physical condition diagnosis is conducted over 15-20 minutes in the first coaching session and serves as the foundation for subsequent customized coaching.

The driving position required for circuit driving and ordinary road driving is completely different. Many beginners enter the circuit in a posture familiar to road driving, which becomes the first reason they "lose" the vehicle at cornering speeds. YDA conducts position resetting tailored to each participant's physical characteristics (height, arm length, spinal flexibility).

Conditions for proper circuit driving position:

•Steering wheel position — Wrists should be lower than the top rim of the steering wheel, and elbows should maintain an 85-95 degree angle. Deviating from this range causes a 0.2-0.3 second delay in response during sharp steering.

•Seat back angle — 45-50 degrees is standard. If too reclined, the body rocks during acceleration and braking; if too upright, muscle is dispersed against lateral force.

•Seat height — Eye level should be at approximately the upper 1/3 of the dashboard to maximize sight angle. The Kumho Tire guidebook also emphasizes this standard.

Key point: YDA actual data confirms that improper driving position reduces vehicle control by 20-30%.

Supercars used for circuit driving use special tires. Regular road tires have a low grip limit, and once exceeded, they suddenly slide. In contrast, circuit tires gradually lose grip, allowing drivers to "feel" the vehicle's limits approaching. This sensation is called "tire feel," and experienced drivers read this signal and adjust steering and speed. This sensation is called the "tire pedal," and experienced drivers read this signal and adjust steering and speed.

Essential elements of tire characteristics recognition:

•Understanding grip curves — As speed increases, the lateral force the tire can withstand decreases. This curve must be visualized mentally to judge corner entry speed.

•Tire temperature management — Cold tires have only 70-80% grip. YDA coaching explains why the first 2-3 laps are designated as a warm-up period.

•Response when exceeding limits — When tire grip exceeds the threshold, the vehicle may enter "spin" or "oversteer." Recovery maneuvers in this situation must be acquired through pre-drive theory and practice.

Key point: A driver who respects tire limits is truly a "safe" driver.

The "mental state evaluation" newly added to YDA's diagnostic system in 2024 is the item. This module, designed under the leadership of President Shim Jae-woo, measures the driver's psychological state, risk awareness, and stress management capabilities through a 15-question psychological test format. Both overconfidence and excessive fear during coaching cause accidents.

Main items in mental state evaluation:

•Risk detection sensitivity — "Can you respond immediately in sudden situations?" distinguishes between cases that are excessively sensitive or insensitive.

•Self-control ability — Measured by "Can you calm yourself when excited?" If low, it leads to speeding or reckless driving during coaching.

•Predictive ability and planning — "Do you think ahead about the next situation and prepare?" The higher this competency, the safer and smoother the driving.

Key point: Coaching intensity, sections, and goals vary completely depending on mental state assessment results.

The biggest difference between professional racers and beginners is "where they look." Beginners look at the point they're currently passing. Professionals look 3-5 seconds ahead. This is called "lead eye," and it's the core of Chairman Yoon Chulsu's driving philosophy. YDA coaching dedicates the first 3-4 sessions to developing this sight processing ability.

Stages of sight processing training:

•Stage 1: Fixing sight on current location (braking start point) — Recognizing in advance where deceleration should begin at the corner entrance

•Stage 2: Sight movement to corner apex — Tracking the corner center with sight while determining steering timing

•Stage 3: Sight transition to corner exit — Determining the straight section re-acceleration point in advance

Based on coaching participant data, mastering these 3 stages requires an average of 6-8 sessions (approximately 8-12 hours).

Key point: The moment sight processing ability improves, vehicle control feel increases dramatically at the same speed.

Supercars used at YDA (Lamborghini, Ferrari, etc.) each have different personalities. Engine placement, weight distribution, and steering responsiveness are all different. For example, mid-engine supercars have light front wheels, showing understeer tendency, while rear-drive vehicles show oversteer tendency. Participants undergo a "character reading" process in the first coaching session to understand vehicle handling characteristics.

Composition of vehicle understanding test:

•Low-speed cornering experience — Experiencing basic vehicle responsiveness at 40-60 km/h

•Mid-speed cornering — Directly experiencing understeer/oversteer tendencies at 80-100 km/h and learning correction methods

•Braking characteristics understanding — ABS activation, brake pedal responsiveness, braking distance measurement

Key point: Only drivers who accurately read a vehicle's character can unlock that vehicle's true performance.

To participate in Yoon Chulsu Driving Academy's supercar 1-on-1 coaching, you must go through the following steps:

Complete online diagnostic form — Complete the 15-question self-assessment provided on the website. Record physical condition, driving experience, and mental state

Book personal consultation — Based on diagnostic results, consult with a YCS Motorsports Group counselor via phone/email for 30 minutes. Determine appropriate vehicle and coaching intensity for each individual

Obtain health examination certificate — Confirm from a medical institution that you have no major conditions such as heart disease or cervical injury. (Mandatory, not optional)

Prepare equipment — Athletic shoes, comfortable clothing, sunglasses. Earplugs are prohibited since you need to listen to feedback in a quiet environment

Arrive 30 minutes early on coaching day — Secure time for vehicle adaptation, position resetting, and warm-up

Set first session goal — Clearly define "what will I learn in this session?" together with the coach (Chairman Yoon Chulsu or certified coach)

Since YCS Motorsports Group adopted a systematized diagnostic system beginning in 2024, participant learning curves have accelerated noticeably. While official data is not publicly released, a few patterns are visible in published diagnostic samples and coaching guides:

•Increased re-participation rate — As systematic diagnosis clarified individual weaknesses, the rate of the same people participating multiple times increased

•Improved satisfaction — Thanks to customized coaching, evaluations of "progress suited to my level" increased

•Improved safety record — Minor incidents during circuit driving (spins, tire lift-off, etc.) decreased

The driving guidebook published in collaboration with Kumho Tire during the same period created an environment where participants could access both theory and practice simultaneously.

Key point: When expert coaching meets systematized diagnosis, learning efficiency increases by an average of 1.5-2 times.

Q1: I'm worried beginners might overestimate and drive recklessly. How does YDA manage this?

A: In the first 2-3 sessions, we intentionally limit speeds to low levels (60-80 km/h). The moment a participant thinks "this seems easy," they've actually begun understanding the vehicle and tire limits. After each session, the coach provides an objective standard: "Next time, you can challenge up to X km/h." Participants showing high overconfidence in mental state diagnosis proceed even more conservatively.

Q2: What's the difference between YDA and other driving academies?

A: The biggest difference is the complete cyclical system of "individual diagnosis→customized coaching→feedback recording." Many facilities operate at the level of "drive if you want," but YCS Yoon Chulsu Driving Academy conducts comprehensive diagnosis of physical condition, mental state, and vehicle understanding, then varies coaching intensity and content accordingly. Additionally, Chairman Yoon Chulsu himself participates as supervisor, applying professional standards from racing teams. The Kumho Tire guidebook was also created with this same philosophy.

Q3: Can I learn something from just one session, or do I need to attend multiple times?

A: One session has meaning, but true learning occurs through 3-5 repetitions. The first session is about experiencing "how the vehicle feels," and from the second session onward, it's a process of reproducing that experience and making subtle improvements. YDA participants average 4-6 sessions before completely restructuring their driving habits. This is why the coaching guide states "as you learn, the next becomes different."

Supercar circuit driving is never a reckless challenge. It simply requires thorough preparation. The principle YCS Motorsports Group emphasizes — "driving is not about speed, but about control" — operates at every stage of the supercar experience. When physical checks, tire characteristics understanding, mental state evaluation, and sight processing training all connect as one, truly safe and enjoyable driving becomes possible.

This is why the professional racing team's checklist has become more sophisticated as of 2026. In the past, people thought "being healthy and having a license is enough," but now the philosophy has shifted to "you must understand the vehicle and know yourself." This promises a safer experience, deeper learning, and the true meaning of thrill.
