A Porsche 928 S4, converted by Gemballa, is currently available for sale in Germany. This vehicle underwent the "Wide Version II" conversion at Gemballa's workshop in Leonberg, west of Stuttgart. The modifications included new bumpers designed to accommodate wider wheel arches, deep side skirts, vented rear quarters, and two rear spoilers, one of which is a wraparound ducktail.
The exterior of the car, including the centers of its 17-inch BBS three-piece wheels, was painted yellow. The interior features black leather and Alcantara with yellow stitching, matching seat belts, embroidered Gemballa headrests, a branded steering wheel boss, and quilted leather floor mats.
Mechanically, the car retains its naturally aspirated, four-cam 5.0-liter V8 engine, which produces approximately 316 hp (320 PS). This engine is paired with a four-speed automatic transmission that drives the rear wheels. The vehicle is equipped with Porsche’s electronically controlled PSD limited-slip differential, which was standard for the 1990 model year. Additional features include a quad-exit sports exhaust system located on the driver’s side and KW V3 Competition suspension.
The odometer shows 86,326 km (53,400 miles), though this figure is not warranted. The listing indicates that over €50,000 was reportedly spent at a Porsche Classic Centre in 2021.
