There’s no doubt that Porsche 964’s transformed by RWB are among the most desirable tuner cars on the market, predominantly because of their overt styling and array of customization options.

However, do all of the Japanese tuners modifications harm its on-road performance? To find out, one YouTube channel jumped behind the wheel of an RWB 964 owned by automotive designer Jon Sibal.

Unlike many of RWB’s creations, Sibal’s car doesn’t feature a huge rear wing or a front lip which would scrape of the tiniest of pebbles. Instead, Sibal opted for a far cleaner look which primarily consists of a new front bumper, the customary flared front and rear wheel arches and some subtle changes at the rear, including a unique wing.

While the exterior is obviously modified, Sibal’s RWB has many more interior changes and upgrades beneath the bodywork. In terms of its chassis, the car has new coilover suspension, custom sway bars, a strut brace and new engine mounts. There’s also Pirelli P Zero Rosso tires on Work Meister three-piece wheels.

Powering the car is an air-cooled 3.6-liter flat-six mated to a 5-speed manual transmission. The exhaust system even consists of mufflers from the Porsche 997.2 911 GT3.
