SW388 15″5.0J +45 4H100

Lighter weight that creates advantages to acceleration, deceleration, cornering, and manipulating cars.

Among them, the weight reduction of tires and wheels, which is said to be under the spring, is a very effective part.

The SPOON SPORTS icon, the forged aluminum wheel, SW388, was named from 3.88 kg of wheel, and the lightness was surprising to the world at the beginning of 1996.

However, after a quarter of the first model release, wheel safety standards have changed dramatically, and the weight has become very difficult.

Nevertheless, we thought that the weight reduction was the optimal solution that drives the car comfortably, and the target amount of SW388, which is newly developed for N-ONE, is 3.88 kg.

Although it is the same 15 inches as the initial model, the current strength standards are very strict, and the conventional method has made it difficult to achieve the current strength standard.

Repeat the fatigue strength simulation and analysis on the desk, make a prototype, and challenge the strength test. The engineer has repeated the process many times, and this wheel, which has introduced many new technologies, has achieved 3.84 kg lighter than the target.

Ultra -lightweight forged aluminum wheel “SW388”, please experience the true weight.

SW388 special shape

1. Step -shaped center pad

The wheel center surface is step -shaped (staircase), and the rigidity of the rigidity around the mounting hole and the weight reduction are achieved.

2. Wave Shape Well

A part of the wel (valve seat part) is processed into a wavy and lighter weight. Furthermore, heat dissipation and rigidity are improved.

3.Ω cross section spokes

The cross section of the spoke is cut out and the weight is reduced. Furthermore, heat dissipation and rigidity are improved.

4, the arched mounting surface

A donut -shaped paddy such as a “arch” is applied to the hub junction, and the pressure surface pressure is concentrated on the outer periphery to avoid the concentration of stress, and the wheel strength and the mounting rigidity are enhanced.

Hub bolt and concave layouts are the key to the design of SW388.

5, Convex surface bead sheet

Ensuring the strength and rigidity of the bead seat portion that receives stress from the tires, and preventing the spinning of wheels and tires when wearing high grip tires.

Weight Redaction Has a Big Impact on Car Acceleration and Decelation, Corning, and Maneeuvering.

SINCE WHEELS PLAY A HUGE ROLE IN All the ABOVE, Their Weight Redaction Means a Lot to the Car.

The Iconic Forged Aluminium SW388 NameD After ITS ACTUAL Weight of 3.88 kg First Came Out in 1996 And Surprised The Walld with Is Lightness.

25 YEARS SINCE THEN HOWEVER SAFETY STANDARDS HAVE SIGNIFICANTLY CHANGED AND REDUCING THE WEIGHT BECAME EXTREMELY DIFFFICULT.

We NeverTheless DecideDed to Same 3.88kg Target Weight for the New N-ONE WHEELS.

It was not Easy to the Same Production Method Based on the Current Standards, Even Though It Has The Same 15-inch size.

HOURS OF DESK WORK, FATIGUE STRENGTH SIMULATION ANALYSIS, Protypes and Tests Repeated by The Engineers over and Over and OFF e Proud to Announce Even Lighter Weight of 3.84kg.

Now we Cannot Wait for You to Experience IT.

Here is what’s New:

1.Stepped Shape Center Pad

Wheel Center Surface Now Has a STEP SHAPE (Picture A Staircase) to Increases and Reduce Weight.

2. Wave Shaped Wheel Well

A Part of the well (value seat part) is Made into a Wave Shape for Weight Reduction. Heat Dission and Rigidity Further IMPROVED.

3.Ω Cross-Section Spokes

Spoke Cross Section Hollowed Out to Reduce Weight. Heat Dissipation and Rigital Further Improved.

4.Arched Mounting Surface

Special Arched Donut Shaped GOUGE TO ENSURE MOURE MOURE MOUREDITY AND AVOID AVOID STRESS CONCUENTRATION by CRIMPING THE SURFACE PRESSURE ON TO OUTER PART.

Hub bolts and hollow hub repressenting ICONIC SW388 design.

5. Convex Cross-Section Bead Sheet

StrengtheneD Bead Part Part Takes Takes THE STRESS from the Tire, IMPROVED RIGIDIDITY, WHEEL, and High Grip Tire Slip Prevention.
