Porsche 992 GT3 RS Wheel Comparison | RT88 vs E89 vs OEM Magnesium

The Porsche 992 GT3 RS is a precision machine. Wheels play a huge role in its performance and handling. In this guide, we compare three top options: BBS RT88, BBS E89, and the Porsche 992 GT3 RS OEM Magnesium wheels. This helps you choose the best fit for your goals.

Overview of 992 GT3 RS wheels

Wheels affect weight, stiffness and handling. They also shape the car’s character. The 992 GT3 RS can wear lightweight forged wheels or the ultra-light OEM magnesium set. Below, we break down each option.

BBS RT88 Wheels

BBS RT88 wheels are forged performance wheels. They combine modern design with proven strength. First, RT88 wheels are engineered for track use. They are light, stiff, and reliable.

As a result, you get sharper handling and quicker responses. These wheels also support oversize brakes. In short, RT88 is ideal for drivers who want a performance-focused upgrade over stock.

BBS E89 Wheels

BBS E89 wheels are also forged. They offer a slightly different design and load profile compared to RT88. E89 wheels balance street comfort and track capability.

Compared to the RT88, E89 wheels can feel a bit more compliant. Yet, they still maintain excellent stiffness. This makes them a strong all-around choice, especially if you drive both street and track.

The big problem for these E89 wheels is, that it requires a full brake replacement as these will not fit with the OEM steel or carbon ceramic brakes.

OEM Magnesium Wheels

The OEM magnesium wheels are the lightest option. They come straight from Porsche. Because magnesium is lighter than aluminum alloys, unsprung weight is reduced. This helps acceleration, braking, and suspension response.

However, magnesium can be more delicate. Care must be taken with road debris and chemicals. Still, this remains the true “track-centric” factory choice.
