Can You Fit a New Steering Wheel and Quick Release Without a Boss Kit?
We’re excited to announce that we’ve expanded our B-G boss kit range with brand-new models for BMW, Audi, and Alfa Romeo vehicles! These high-quality boss kits allow you to seamlessly install an aftermarket steering wheel, improving both the driving experience and interior aesthetics of your car. Whether you’re upgrading to a performance-focused wheel for better control on track days or simply personalizing your interior, a B-G boss kit is an essential component for the installation.
Each B-G boss kit is designed to be vehicle-specific, ensuring a perfect fit for your car’s steering column while also featuring a universal bolt pattern on the opposite side. This means they are fully compatible with quick-release kits and aftermarket steering wheels from brands like Sparco, MOMO, OMP, and Sabelt. They also come complete with fixing screws, an Allen key, and a horn button retaining ring, making installation as simple and hassle-free as possible.
What is a Boss Kit and Why Do You Need One?
A boss kit, also known as a steering wheel adapter, is a crucial part of fitting an aftermarket steering wheel to your car. Your vehicle’s factory steering wheel is typically attached directly to the steering column with a unique mounting pattern. A boss kit acts as an adapter, allowing you to install a new performance or motorsport steering wheel with ease.
Many drivers pair a boss kit with a quick-release system, which enhances security by allowing you to remove the steering wheel when parked. This setup is also highly beneficial for motorsport and track use, providing a more ergonomic and responsive driving experience. If you’re looking to improve steering feedback, reduce weight, or simply enhance the look of your car’s interior, upgrading with a B-G boss kit is the perfect solution.
B-G Boss Kits for BMW Vehicles
For BMW owners, our new B-G boss kits cater to a wide range of models, from 1 series up to 5 series BMW’s. Whether you drive a track-ready BMW M3 or a daily-driven 3 Series, these boss kits allow you to install an aftermarket steering wheel while retaining full functionality.
These BMW-specific boss kits feature a direct-fit design, ensuring a secure and straightforward installation. Plus, with a universal bolt pattern, they are compatible with quick-release systems and all major aftermarket steering wheel brands. If you’re looking to enhance your steering precision and driving feel, upgrading your BMW’s steering wheel setup is a fantastic investment.
B-G Boss Kits for Audi Vehicles
For Audi enthusiasts, we now stock B-G boss kits for a variety of models, including Audi S4, S6, and Audi 100. These boss kits ensure a perfect fit for your vehicle’s steering column while allowing you to upgrade to a race-inspired steering wheel.
Installing a B-G boss kit on your Audi lets you take advantage of enhanced steering feedback, reduced weight, and a more aggressive cockpit feel—especially when paired with a quick-release kit. These boss kits are precision-engineered for durability and compatibility, ensuring long-lasting performance.
B-G Boss Kits for Alfa Romeo Vehicles
Alfa Romeo drivers can also take advantage of our new B-G boss kits, specifically designed for models like the Alfa Romeo 147, Spyder, and GT. Known for their passionate driving experience, Alfa Romeos deserve a performance steering upgrade that matches their legendary handling.
With a B-G boss kit, you can swap out your factory steering wheel for a sleek, performance-oriented alternative, whether it’s a classic three-spoke design or a flat-bottom racing wheel. The universal bolt pattern allows compatibility with a wide range of quick-release kits and aftermarket steering wheels, ensuring you can create a customized driving experience.
Find the Right Boss Kit for Your Car
A boss kit is an essential part of any aftermarket steering wheel installation, providing a secure and vehicle-specific connection between your car’s steering column and the new steering wheel or quick-release hub. Since every car has a different steering shaft design, a universal steering wheel won’t fit directly without a boss kit acting as the bridge between the two.
No matter what vehicle you drive, using a high-quality boss kit ensures a secure, safe, and professional installation.
