Project Description

High-level performance! Last Monday, this Porsche 911 installed BONOSS Forged Lightweight Plus Wheel Spacers, front/rear 15mm (0.6 inches), PCD 5×130, CB 71.5 together with BONOSS Forged Titanium Extended Wheel Bolts. What do wheel spacers do? It allows for installing wheels with a larger center diameter and bigger brake calipers without breaking the fender. They also create proper clearance to fill the wheel arches, which gives the car an excellent look. The special Porsche style three-fingered hub-centric design allows the wheel to be properly centered and locked, ensuring no vibration at high-speed rotation. These spacers and bolts are precision-engineered to fit the wheel to the hub. (Thanks NOISE PERFORMANCE for providing these pics)


Within the car marketplace, the Porsche 911 can be the most successful selling luxury sports car on the planet. It is appreciated for the advanced technology, lavish features and ultimate reliability. Furthermore, its cultural impact is even broader. Modified by the private teams or the factory for racing, rallying, or any other form of automotive competition. It’s very enjoyable to drive even on winding switchback roadways because of its accurate steering, stable control, and powerful turbocharged engine.

Three-fingered Hubcentric Design for Porsche

Most cars come with a ring-type hub structure design. But the new Porsche models are equipped with the three-fingered style hub structure-a three-fingered centering ring, for example, the 911 997, the Panamera 970. The three-fingered style hub allows the wheel to be properly centered and locked, ensuring no vibration at high-speed rotation. Considering this special construction, the traditional hub-centric wheel spacers may not suit properly the three-fingered style hub, leaving a certain clearance.
