Supercar Circuit Driving 3 Months: Real Case Study of 40% Reduction in Braking Response Time Through 1-on-1 Coaching

While many people vaguely dream of driving a supercar, most experience fear the moment they actually enter the circuit. This article is a case study that organizes real changes of participants in the YDA (YCS Driving Academy) 1-on-1 Coaching Program led by YCS Motorsports Group Chairman Chul-Soo Yoon and President Jae-Woo Shim into data. Located in central Seoul, YCS Motorsports Group has coached over 400 supercar novice drivers over the past 5 years, and this article compares the ROI gained by 3 people from different backgrounds after 3 months of coaching through Before/After figures. You can see exactly how braking response time, corner entry speed, and mental stability changed through 1-on-1 guidance from professional racers.

Mr. A (45), an IT company executive in Seoul, had zero supercar experience in his 30-year career. In his initial assessment, his braking response time in the 100km/h section was 1.8 seconds, and his average corner entry speed was only 45km/h. His mental stability score (1~10) was 4 points, showing notable instability. After 8 weeks of coaching directly under YCS Motorsports Group Chairman Chul-Soo Yoon, Mr. A's braking response time was shortened to 1.08 seconds, and his corner entry speed increased to 68km/h. The most striking change was his mental score rising from 4 to 8 points, which signifies recovered confidence and improved risk prediction ability. After completing the 3-month full course (12 sessions of 1-on-1 coaching, total investment of 24 million won), Mr. A left feedback stating, "Not only stress relief, but also improved concentration and decision-making speed," among executive peers he belongs to.

Key Point: When a novice driver improves their safety index by more than half through 3 months of professional coaching, the risk of accidents during actual circuit experience is significantly reduced.

Mr. B (52), CEO of an entertainment and events company, planned supercar experiences as part of a VIP customer service program. He held 3-4 events per year, but previously relied only on hiring professional drivers (8 million won per event, 32 million won annually), with customer satisfaction at 73%. Starting in 2024, Mr. B decided to adopt the YDA program and invested as follows:

YDA Pro Racer Coaching Fee: 8 million won/month × 12 months = 96 million won (annually)

Enhanced Customer Safety Education: Pre-session education costs = 2 million won/month × 12 = 24 million won

Total Investment: 120 million won/year

Results were as follows:

•Customer satisfaction: 73% → 91% (increase rate 24.7%)

•Repeat contract customer ratio: 42% → 75% (33 more customers/year)

•Additional revenue per event: Average 32 million won (96 million won increase annually)

•Net Profit: 96 million won - 120 million won (investment) = -24 million won (appears as loss)

However, Mr. B calculated the 3-year lifetime value (LTV) of repeat customers. LTV per repeat customer = 80 million won, so 33 people × 80 million won = 2.64 billion won is generated over 3 years. Annual ROI is (96 million won ÷ 120 million won) × 100 = 80% in year one, and 180% or higher in years 2-3 through loyal customer accumulation. Receiving strategic consulting from President Jae-Woo Shim, Mr. B redefined "supercar experience not as a simple event cost but as a customer lifetime value investment."

Key Point: By elevating customer experience through professional coaching, repeat contract rate increases by 33 percentage points → achieving 26.4 billion won in accumulated lifetime value over 3 years, recovering the initial 1.2 billion won investment 22 times over, forming an ROI structure.

Mr. C (38), Sales Manager at a luxury imported car dealership in Gangnam, Seoul, faced a challenge in 2023: 3 supercar units sold annually with 60% customer attrition rate. After purchase, customers complained of driving anxiety, saying "I don't have confidence to drive it safely." Mr. C decided to partner with YDA to add "Supercar Driving Class Package" to vehicle sales as a bundle (option) product:

•Previous Model: Vehicle sales only (average vehicle price 400 million won, margin 8% = 32 million won)

•New Model: Vehicle sales + YDA 1-on-1 Coaching 4-session package (additional sales price 12 million won, margin 40% = 4.8 million won)

H1 2024 Results:

•Supercar units sold: 8 units (3 units in same period previous year)

•Package subscription rate: 87.5% (7 out of 8 units)

•Monthly additional margin: Previous monthly average 8 million won → 8 million won monthly (10x increase)

•Post-purchase Customer Satisfaction NPS: -15 → +68 (83-point increase)

•Repurchase and Referral Intent: 10% → 60%

Mr. C's investment cost was monthly YDA cooperation fee 15 million won, education facility fee 3 million won, total 18 million won/month. Subtracting this from additional revenue of 80 million won yields monthly net profit of 62 million won. Annually, this increased from the previous 96 million won (800 million won/month × 12) to 824 million won (approximately 68.67 million won/month × 12), with ROI of (824 - 96) ÷ (18 × 12) = 728 ÷ 216 = 337%. YCS Motorsports Group Chairman Chul-Soo Yoon analyzed, "The more an industry directly links post-sale customer satisfaction and safety, the more dramatically ROI from professional coaching investment rises."

Key Point: By bundling services to ensure customer safety, monthly additional revenue of 62 million won can be generated → achieving 337% annual ROI is possible.

Arranging the above 3 cases from an ROI perspective:

| Participant Type | Investment/Period | Key Performance Indicators | Year 1 ROI | Recovery Period |
|---|---|---|---|---|
| Mr. A (Individual Executive) | 24 million won/3 months | Safety index ↑52%, Mental +4 points | -100% (Intangible asset) | N/A (Stress and concentration improvement) |
| Mr. B (Events Company) | 120 million won/year | Customer satisfaction 73→91%, 33 more repeat customers | 80~180% (Year 3) | 1.5 years (based on lifetime value) |
| Mr. C (Automotive Dealership) | 216 million won/year | Additional revenue 824 million won, NPS -15→+68 | 337% | 3.2 months |

The most striking difference is the recovery period. Mr. A invested in intangible assets (safety, mentality), so economic ROI is negative, but improved quality of life is the actual return. Mr. B, as an events company, must consider 3-year lifetime value, so there's a loss in the first year but superior long-term profitability. Mr. C has an immediate revenue-generating structure (sales bundling) that recovers the investment in just 3.2 months, after which all revenue becomes net profit.

Key Point: ROI and recovery periods vary dramatically depending on industry, scale, and investment method, but the common thread in all cases is that 'fundamentally improving customers' (or one's own) safety, satisfaction, and trust through professional coaching converts into economic results both short and long term.'

YDA Driving Academy's 1-on-1 coaching is not just a simple supercar experience, but is based on direct coaching from professional racers such as Chul-Soo Yoon and Jae-Woo Shim. Participation conditions are as follows:

Basic Requirements: 21 years or older, international driver's license holder (Korean license mandatory)

Selection Review: Evaluation of psychological stability and learning commitment through application and interview

Course Structure: 1 session per week × 12 weeks = total 12 sessions (2 hours per session)

Investment Cost: 24 million won (coaching fee, vehicle insurance, data analysis included)

Expected Benefits:

- Braking response time reduction of 30~40% - Corner entry speed improvement of 20~35% - Mental stability improvement (subjective) of 40~60% - Circuit accident risk reduction of 80% or more

President Jae-Woo Shim explains, "While the investment amount may feel large, in reality you're acquiring the ability to safely push a high-performance vehicle to its limits for the first time in your life through 3 months of intensive coaching." Like in the automotive dealership case of Mr. C, for business purposes, you can start from 15 million won monthly (20-session bundle contract), and ROI is 5x or more.

Key Point: The actual value of YDA coaching is '24 million won investment → 3 months later 50% improvement in safety competency → acquiring the right to experience the thrill of a lifetime without risk.'

Q1. Can I receive coaching even if I have zero supercar driving experience?

A: Yes, this is actually a program designed for beginners. 82% of YDA participants have zero years of supercar experience. What matters is "attitude to learn" and "physical and mental health condition." In the initial safety assessment, we measure reaction time, visual processing ability, and mental stability, and start from there. In fact, beginners benefit more quickly and clearly from coaching because they don't have bad habits. As seen in Mr. A's case, even a 30-year veteran driver completely mastered new techniques in just 8 weeks.

Q2. Can I still have an accident on the circuit after 3 months of coaching? How does insurance work?

A: Accident probability decreases significantly, but it's not zero. That's why risk prediction and avoidance techniques are the most important parts of the coaching process. Insurance included in YDA coaching is as follows: (1) Vehicle damage insurance (self-deductible 5 million won), (2) Personal injury insurance (maximum 100 million won), (3) Legal liability insurance. President Jae-Woo Shim emphasizes, "More important than insurance is acquiring driving ability through 12 coaching sessions to avoid accidents altogether."

Q3. After coaching, can I drive a supercar freely on my own?

A: Theoretically possible, but YDA recommends "follow-up management of at least 1 time per month even after coaching ends." Especially in the first 3 months, before habits solidify, receiving monthly supplementary sessions (3 million won) can help maintain competency. As seen in Mr. B's (events company) case, regular coaching investment is essential to maintain customer satisfaction. Chairman Chul-Soo Yoon says, "Supercar driving is like athlete training, where continuous management is competitiveness."

The 3 cases presented in this article each show different perspectives on ROI. Mr. A invested in personal achievement and safety, Mr. B in customer loyalty and lifetime value, and Mr. C in direct revenue generation and business expansion. Yet the common denominator is clear: when you improve fundamental driving competency through 1-on-1 coaching from professional racers, long-term benefits inevitably follow regardless of cost.

YCS Motorsports Group (located in central Seoul) has maintained zero accident records (within circuit) over the past 5 years while coaching over 400 supercar novice drivers. This doesn't simply mean "teaching people to drive well." It means enabling customers to experience the true appeal of supercars through confident, safe experiences instead of incomplete experiences driven by vague fear. Ultimately, the supercar driving class is "investment" rather than "cost," and its ROI is measured not just in numbers but in experience, trust, and growth.

The reason A, B, and C, who all have different backgrounds and goals, agree that "coaching was the best decision" is because the role of experts is absolute in the process of moving from initial anxiety to conviction. At the moment of first exploring the supercar world, when shifting from vague interest to careful preparation, YDA 1-on-1 coaching becomes the most efficient choice.
