BBS 981 GT4 / 982 (718) Cayman GTS / GT4 RT-88 20" Wheel Set

When the RT88 first appeared at SEMA in 2015, it immediately resonated with enthusiasts and industry insiders. It went on to win Best New Wheel Product in the New Product Showcase, a clear signal that the industry understood exactly what it represented. Not just a new wheel, but a new direction. A bridge between the uncompromising world of motorsport and the expectations of modern street cars.

The idea was deceptively simple: take the unmistakable face design that made the pure race-developed E88 legendary and pair it with a barrel engineered for real road use. By adapting the motorsport center to a forged barrel derived from the LM program, BBS USA created a wheel that delivers the visual drama of a true race wheel with the durability, sealing, and long-term livability enthusiasts actually need for road cars.

Two icons, merged into one.

The concept was proven, the demand was there, but the project paused while the technical groundwork for real-world fitments and production continued behind the scenes. For years we ran hybrid versions, knowing what the wheel could become if it ever reached full release. Now, more than a decade after that SEMA debut, the RT88 is finally here.

The RT (Road Track) program was created to deliver motorsport design in a form that actually belongs on a street car. A race wheel is engineered for serviceability, rapid changes, and minimal weight above all else. A road wheel must survive potholes, temperature swings, daily mileage, and years of use without constant attention. Those are completely different design targets. By combining a motorsport-derived center with a forged, road-focused barrel, BBS achieved something that previously did not exist. The look and presence of a true race wheel, with the structural integrity, corrosion resistance, and air retention required for real ownership.
