Setiap kali anda menukar gear, anda tidak mempunyai masa untuk melihat meter anda, dan mungkin dalam keadaan tertentu anda perlu menukar gear dengan RPM tambahan seperti ketika mendaki bukit. Di sini deria keenam anda sangat-sangat diperlukan.

Downshift atau menukar gear ke bawah juga memerlukan anda teknik baru dipanggil "double clutching". Apabila anda menukar gear ke bawah, gerigi akan menghalang anda untuk masuk dengan lancar, apa yang perlu anda lakukan di sini adalah dengan menggerakkan gear berkenaan. Katakan anda dalam gear 4 ke gear 3.
1.Tekan clutch anda
2. masukkan ke gear Neutral
3. lepaskan clutch
4. tekan pedal minyak untuk menaikkan RPM kereta anda
5. lepaskan pedal minyak dan dalam masa yang sama tekan pedal clutch
6.masukkan gear 3 dan lepaskan clutch.

these action is to ensure that gearshift is smooth. what happens when gear shift is smooth? try placing a cup of water in the car. if your gear shift is not smooth the water will splash out. why? because acceleration of the cup+car body is different than that water in it. so water will try to maintain its inertia and to remain static. however, while remaining static it splash out because the cup is moving forward but water stays in the same place. if you can control the gear shifting via LC2K and enable the water to accelerate along with the cup+car body, it will stay in the cup without splashing...same concept as Initial D to prevent Tofu from pecah...

now assume it happens to the PETROL. petrol is HIGHLY evaporating substance and upon splashing everywhere including inside the tank, it will evaporate(even slightly) and become gas. after it became gas, mana la ada lagi petrol untuk bakar...
