Drifting

Adow... Gak biasa de sehari 2x post

Gpp ya? Huehueheu

Lagi tertarik sama drift, cuma gw gabisa..huks... + gabole jg...blm ada SIM T__T
Asal tau , drift itu aksi kepot2an mobil, cuma bisa dilakuin sama mobil 2WD(RWD(Rear Wheel Drive) dan FWD(Front Wheel Drive)) semisal sedan sport macem Mazda RX(7 & 8), Honda Civic, Toyota Corolla, dll. Knp engga Mitsubishi Lancer? Lancer Evolution kurang cocok buat kepot2an, buktinya di game Juiced2, Lancer Evo VIII kagak ada tulisan "Good Drift Car". Di luar negeri, biasanya mobil Muscle yg jadi andalan kepot2, misal Ford Mustang,Chevy Camaro,Dodge Charger/Challenger. Tentunya Muscle Car enggak murah donk. Bentuknya ngotak, jelek, mahal lagi, tapi orang mau beli? Ya, ingatlah peribahasa "Don't Judge The Book From Its Cover". Mesin yg dipake juga kagak neko2, minim V6, max bisa ampe V12, cuma blm ada pabrikan yg nyoba mesin V12 buat muscle, paling cuma V8 mentok. Bayangin aja, "Minimal" aja V6, tau kan V6 sekenceng apa? Kalo gatau, coba aja bayangin Mitsubishi Galant versi paus/hiu(ud pake V6) digeber sampe sekenceng2nya. Konsekuensinya ya boros BBM, cuma tenaga yg dihasilkan jg gak dikit, 0-100 km/h kurang dari 10 dtk, jelas kenceng dong. Bayangin Jkt - Bandung yg notabene macetnya gile kalo lancar 2 jam aja kg nyampe kali? Hehe. Kalo macet ya borosnya kek apa gabisa dibayangin dah.

Dah2 kok malah ngelantur bahas mesin V6 sama Galant? kita kan mau bahas drifting?

Di Indo, drifting juga engga kalah dari negara2 lain lho. Buktinya di negara kita sering diadain event slalom, yg notabene ga beda jauh ama kepot2an.

Bedanya, Slalom itu teknik U-Turn, kalo Drifting kan gak selalu U-Turn. Intinya, slalom gak selalu drift, drift bukan slalom.

Gambar2 drifting:




Drift pake Toyota Supra, top abis!




drift ampe bumper copot...mantap



kompetisi drift di jepun loh








yap, kalo drifting, tentunya gak pake mobil asal2an, harus cepet n ngepotnya lama, misalnya kalo di Jepang pake Nissan Silvia/180sx/200sx/240sx,Toyota AE86,Mazda RX-7,Nissan A31 Cefiro,Nissan C33 Laurel,Nissan Skyline(RWD Version),Nissan 350z,Toyota Altezza,Toyota Chaser,Toyota Mark II,Toyota Supra Mark IV, Toyota MZ20 Soarer,Honda S2000,Acura/Honda NSX,Ford Mustang, Mazda Miata MX-5. Di Amrik, ketambahan pesaing, Dodge Charger,Chrysler LLC,Pontiac Solstice,Holden Commodore,Holden Monaro. Di negara lain jg ada yg pake mobil lokal favorit, semisal merek Jaguar,Vauxhall,BMW seri 3,Mercedes,Porsche,Alfa Romeo.

Teknik Drifting (bahasa inggris, gabisa artiinnya...hehehe)

Techniques for inducing drift

The basic driving techniques used in drifting are constant, though each car and driver will employ some subset of these techniques. A similarity for all drifting techniques is to be smooth and practice. These techniques include

Beginner techniques

These techniques do not use weight transition, so are typically the first thing the novice drifter learns.[9] However they are still used by the most experienced drifters, and require skill to execute properly. These techniques aim to induce a loss of traction on the rear wheels, either by locking the wheel (hand brake drift) or using enough power from the engine to break the traction force (power-oversteer and clutch kick).

Hand brake drift

Hand brake is a lever that stops the rear wheel so it upsets the rear wheels grip and it tends to drift. Hand brake is one of the fastest, easiest, and most dangerous methods of drifting. It can also damage the cars axels, stall the engine, ruin the rubber on the tires, etc. There are many ways for this not to happen but I'll show you three examples.

1st:

* Come to a corner with plenty of speed like you would do in a regular grip race.
* Let go of the gas, hold the clutch and pull the handbrake just enough to upset the rear end.
* Gas and let go of the clutch at the same time.
* Control the drift all the way.

2nd

* Come to a corner with plenty of speed like you would do in a regular grip race.
* Let go of the gas and pull the hand brake. to the optimum angle. Then let go.
* Control the drift all the way.

3rd

* Come to a corner with plenty of speed like you would do in a regular grip race but this time, 5-20 MPH slower and or if mastered, in a higher rear.
* Hold the clutch and gas it just on the redline or about 6000-8300 rpm (on dial says 6-8.3 or 60-83) and hold the handbrake to the optimum angle. Then let go.
* Let go of the clutch and gas it until controllable.
* Control the drift all the way.

Power oversteer or Powerslide

It is usually done at the corner exit by stepping on the gas hard, to slide side ways out of the corner. It is most commonly employed by beginners because it teaches steering and throttle control without the danger of an actual entry oriented drift.

In low-power cars power oversteer can be achieved by applying excessive amount of throttle at the end of a shift. As you are releasing the clutch during a shift, or immediately before that while the clutch is still depressed, press accelerator all the way to send more power to the rear wheels than is necessary for a smooth upshift. If done during a turn, the car will begin to slide. This technique can be used to initiate a drift at very low speeds in an underpowered car (e.g., when shifting from 1st to 2nd gear), and to enter in a higher gear while accelerating all the way up to the turn (e.g., accelerate in 2nd on the straight and shift into 3rd as you enter the turn).

The sequence of actions is as follows:

* Easily feather the gas in the straight line leading to the turn.
* Turn the steering wheel to begin the turn.
* Floor the accelerator.
* Wait for the car to go sideways, then countersteer and control the slide and proceed to exit the corner.

Depending on how much power the car is making it is possible to keep the gas pedal floored from the shift throughout the entire drift, and in a low-power car this is often necessary.

Shift lock (compression slide)

Initiated by downshifting (usually from third to second or fourth to third, and using a very fast shift) instead of braking, without rev-matching, causing the drive wheels to lock momentarily. Helpful for very tight corners, allowing the driver to approach the corner at a slower speed and lower revs, while allowing quick acceleration when exiting the corner. This technique can be very damaging to the engine if mis-used as the ECU is unable to rev limit when the engine is oversped by the rear wheels. Premature downshifters are called "Rod Stretchers".

Clutch Kick

This is done by "kicking" the clutch (pushing in, then out, usually more than one time in a drift for adjustment in a very fast manner) to send a shock through the powertrain, upsetting the car's balance. This causes the rear wheels to slip. The foot should be at an angle (heel-toe) so the brake and gas may be pressed as well, this being needed to control speed and stop from spinning out in the drift.

Clutch kick can also be used during a drift to gain angle at the expense of speed. If the car is about to straighten itself out, kicking the clutch will cause it to rotate more. However since power delivery is interrupted while the clutch is depressed the car will lose some speed during the process and damage the gears and crank shaft. The steps to clutch kick:

* Start driving into a corner but slower, and/or in a higher gear.
* Turn into the corner.
* Gas and a split second later you gas, keep tapping the clutch to make the wheels spin to slide but don't let go of the gas when clutching.
* Control the spin with the handbrake, brake, or gas.

(If nessesary, keep popping the clutch to keep the wheels sliding)

Weight transition techniques

These techniques employ a further concept of weight transition. When a vehicle has the load towards the front, the back wheels have less grip than the front, causing an oversteer condition that can initiate a drift.

Braking drift

This drift is performed by braking into a corner, so that the car can transfer weight to the front. This is immediately followed by throttle, which in an RWD car causes the rear wheels to lose traction. FWD cars can also use this technique as it does not depend on the rear wheels being driven. In FWD cars the front wheels are not allowed to lock due to the continuous power, the rear wheels locks easily due to weight transfer and due to the general front heavy design of FWDs. Good performance brake pads will help this technique.


Inertia (Feint) drift or Scandinavian flick

This is done by transferring the weight of the car towards the outside of a turn by first turning away from the turn and then quickly turning back using the inertia of the rear of the car to swing into the desired drifting line. Sometimes the hand-brake will be applied while transferring the weight of the car towards the outside to lock the rear wheels and help the rear swing outwards. This type of drifting causes the car to accelerate faster afterwards, because of momentum built up while drifting.

Note that the actual scandinavian flick maneuver in rally driving is more complex than feint drifting. In scandinavian flick the tires are intentionally locked by braking hard right after turning a little away from the corner. While the wheels are locked, the driver applies steering input into the corner, adds throttle while still braking and then rapidly releases the brake pedal. This causes the car to slingshot itself through the corner.

Kansei, Lift off, or Taking In

[13] - By letting off the accelerator while cornering at very high speeds, cars with relatively neutral handling will begin to slide, simply from the weight transfer resulting from engine braking. The drift is controlled afterwards by steering inputs from the driver and light pedal work, similar to the Braking drift.

Dirt drop

This is done by dropping the rear tires off the sealed road onto dirt, or whatever low-grip surface borders the road, to maintain or gain drift angle. Also colloquially called "Dirt Turbo"

Choku-Dori/Manji (Pendulum)

Otherwise known as over-sway, this technique is done by swaying the car's weight back and forth on straightaways, using countersteer and throttle to maintain a large angle. This is a show maneuver that usually involves many cars following the same line. The car will be drifting straight and will be drifting side to side.

Advanced Drifting Technique

This is very useful if you have mastered all the techniques of drifting and have carefuly tuned your car with your style. If you want to master this technique, you must get good tires that have grip and can be able to drift. Many profesionals upgrade their cars from 200-1000 hp but don't go over 400 hp if you are a beginner. And make sure to put enough touque because horsepower isn't everything in drifting.

What you need is to turn off your ESP (Electronic Stability Control(Equiped in many Mercedes-Benz)), TC (Traction Control)off, require a Manual Transmission with a clutch pedal and the clutch must be 2-3 plates. Also, you will need a FR, RWD, AWD (4WD) with a 0/100-20/80 torque distrubution (front/rear), ABS can be off or disabled. Stiff suspension front and back depending on your style and must be as low from the ground as possible but not too low that it scrapes the ground (50-90 mm off the ground), and you need a LSD (Limited Slip Differential). For safety, buy a racing seat with a 4 point seat belt and a 6 or 8 point roll cage. All right. On to the steps.

Kanji type 1:

* Come up to a corner at a fair rate of speed like in a race track.
* Push the Brakes 50 meters away from the racing line for braking but don't slam on the brakes but push it about 50%.
* Feint as little as possible.
* Power-over and clutch-kick all the way.
* Use handbrake and clutch-kick to increase angle.

Kanji type 2:

* Come up to a corner at a fair rate of speed like in a race track.
* Push the Brakes 50 meters away from the racing line for braking but don't slam on the brakes but push it about 50%.
* Hold the clutch and rev up to 5000-6500 RPM.
* Pop the clutch and control.
* Use handbrake and clutch-kick to increase angle.

If you want to transition to a different direction, hold the clutch and turn in more and clutch kick or another way is to let go of the gas, turn in, and power over and control. To end a drift is to turn in very fast and hold the clutch until steady.

Drifting tentunya jg ngerusak ban sma bumper. Rata2 mobil drift bumpernya ceper, biar stabil, jadi enggak heran kalo mobil drift sering keilangan bumper *liat gambar Nissan Silvia di atas*. Daya cengkeram ban juga makin berkurang, seiring dipake ngepot terus, jadi mobil kompetisi drift sedia banyak banget ban cadangan di pitstopnya.

Sayang banget, di Indo, drift jalanan dilarang. Mau ngelakuin harus kucing2an sama polisi dulu. Huf.. Di indo sirkuit drift kaga ada, gimana mau drifting? Padahal sering diadain kompetisi drifting, komunitas drifter juga ada, misalnya DRIFTinc, komunitas drifter di Jaksel(Jakarta Selatan), bahkan PT Multistrada Arah Sarana, produsen ban Achilles di Indo juga gandeng Indonesia Drifting Community(IDC). Sayang, kurangnya sarana berlatih membuat drift di Indo enggak sebaik negara2 lain.

Wish i'd try this on the future :(.
