best tyres for drift


The ADVAN Neova AD07 is the Extreme Performance Summer tire member of Yokohama's global family of ADVAN performance tires developed for sports car, sports coupe and performance sedan enthusiasts who love sport driving. Used as Original Equipment (O.E.) on the Lotus Elise, the ADVAN Neova AD07 is designed to provide high levels of traction, responsive handling and driving control in dry and wet road conditions. The ADVAN Neova AD07 is not intended for cold temperatures or snow.

The ADVAN Neova AD07 molds a "fine particle" Micro Silica (MS) tread compound (to provide greater road surface adhesion) into a directional tread pattern that features massive tread blocks with rounded edges to increase cornering stability and steering response while promoting more even wear. Five large circumferential and multiple directionally aligned lateral grooves resist hydroplaning and enhance wet traction. The tire's structure includes two wide steel belts reinforced by spirally wound nylon to provide strength and uniform ride quality and high-speed capability while the sidewalls are tuned to resist lateral deflection providing handling control and cornering stability.

Like the motorsports tires this Extreme Performance street tire has evolved from, the ADVAN Neova AD07 radial's construction and compounds have been tuned to maximize the tire's traction and performance within a specific range of ambient temperatures. Therefore, unlike less highly-tuned tires, Yokohama's care instructions specify that due to its compound characteristics, ADVAN Neova tires must be used and stored at temperatures above -10 degrees Celsius (14 degrees Fahrenheit) to maintain its performance and avoid tire damage.

A31 + R32 + R33 = ????

family drifter




Nissan Cefiro A31- Drift in a family sedan

Back in the 90s, every guy wanted a Nissan skyline R32 or Honda Integra type R (DC2). They overlooked a performance car that Nissan produced which gained popularity as a Drift machine in Japan - The Nissan Cefiro A31.

Released in September 1988 to the Japanese Domestic Market, the A31 series included many hi-tech features, such as HICAS (Nissan’s rear wheel steering system), sonar controlled electronic damping, automatic headlights, and an automatic electric rear view mirror.

Cefiro engines were known as RB engines, came in a wide variation of sorts. The stock, untouched ones were:

* RB20E - single-cam (85 to 96 kW (115 to 130 ps) @ 5600 rpm, 167 to 181 N·m (17 to 18,5 kgf·m) @ 4400 rpm)
* RB20ET - single-cam turbocharged (107 kW (145 PS) @ 6000 rpm, 206 N·m (21.0 kgf·m) @ 3200 rpm)
* RB20DE - twin-cam (110 to 114 kW (150 to 155 PS) @ 6400 rpm, 181 to 186 N·m (18.5 to 19 kgf·m) @ 5600 (and later with a NEO-Head 4400 rpm)
* RB20DET - twin-cam turbocharged (158 kW (215 PS) @ 6400 rpm, 265 N·m (27.0 kgf·m) @ 3200 rpm)
* RB20P - single-cam (94 PS @5600 rpm and 142 N·m @2400 rpm)
* RB20DET-R - twin-cam turbocharged (210 ps @6400 rpm and 245 N·m @4800 rpm

Most of the Cefiros came in the RB20E engine, which was underpowered and disappointed lots of drifter wannabes. So what did they do? A RB25DET engine swap, which gives the car higher torque than the RB20DET engine, suited better for drifting.

Many of the Silvia (S13) and Skyline (R32) parts are interchangeable for the A31. That was a very juicy clue, right or not? *wink* And yes, Cefiro A31 is a rear wheel drive, for all the Initial D Touge wannabes.

For ideas on how to mod one, Jerome’s Cefiro should provide you with strong visual aid.

All good things have to come to an end. After production for the cefiro A31 ended in 1993, Nissan never came up with a sports sedan ever like the A31 (Infiniti not counted).

So we mourn the loss of a classic sports sedan. The lucky ones in Australia & Malaysia can still find this vehicle probably at a used car dealer.

The rest of us will simply hope Nissan comes up with another turbocharged-rear wheel beast disguised as a family car again.

drift techniques

Drifting Techniques


Heel Toe Shifting
Learn proper race shifting to get your car into the right gear for drifting. Section also includes double clutch shifting so you can downshift before drifting without blowing out your transmission too quickly.

Power Over Drift
A throttle induced drift, this is performed when entering a corner and using the accelerator to slip the rear wheels, producing heavy oversteer through the turn. You will often need lots of horsepower to make this happen.

E-Brake Drift
This drifting technique is very basic, pull the E-Brake or side brake to induce rear traction loss and balance drift through steering and throttle play. This can also be used to correct errors or fine tune drift angles. Main drift technique used in FWD vehicles, however since it does decrease speeds, e-brake drifting is looked down upon during solo (tansou) type drifting competition.

Clutch Kick Drift
This drifting technique is performed by depressing the clutch pedal on approach or during turn in to a corner. The clutch is "popped" to give a sudden jolt through the driveline to upset rear traction, causing the power wheels to slip. Drifting is maintained by balancing the throttle.

Shift Lock Drift
This is performed by letting the revs drop on downshift into a corner and then releasing the clutch to put stress on the driveline to slow the rear tires inducing over steer. This is like pulling the E-brake through a turn, but this should be performed on wet ground to minimize damage to the driveline. Similar drifting technique to Clutch Kicking.

Dirt Drop Drift
This is performed by dropping the rear tires off the road into the dirt to maintain or gain drift angle without losing power or speed and to set up for the next turn. This technique is very useful for low horsepower cars. Do not attempt this technique at the Drift Session.

Feint Drift
This is performed by rocking the car towards the outside of a turn and then using the rebound of the vehicle's suspension to throw the car into the normal cornering direction. This is heavy rally racing technique used to change vehicle attitudes during cornering.

Jump Drift
In this technique the rear tire on the inside of a turn or apex is bounced over a curb to lose traction resulting in over steer. Do not attempt this technique at the Drift Session.

Braking Drift
This is performed by trail braking into a corner. Loss of grip is obtained and then balanced through steering and throttle motions. This is mainly for medium to low speed corners.

Kansei Drift (Inertia Drift)
This is performed at race speeds. When entering a high speed corner a driver lifts his foot off the throttle to induce a mild oversteer and then balances the drift through steering and throttle motions. The car that is being used for this style of drift should be a neutral balanced car therefore the oversteer will induce itself. If the car plows through any turn this technique will not work.

Long Slide Drift
This is done by pulling the E-brake through a strait to start a high angel drift and to hold this to set up for the turn ahead. This technique can only be done at high speed.

Swaying Drift (Manji Drift)
This is a slow side-to-side faint like drift where the rear end sways back and forth down a strait.
