About the Porsche 911 964 RWB Jonsibal GT Spirit 1:18
TL;DR: GT Spirit's 1:18 resin Porsche 911 964 RWB Jonsibal is a sealed, one-piece casting of Rauh-Welt Begriff's widebody tuner interpretation of the 964. New and factory-packaged, its flared arches and dramatic stance are cast without a single hinge line to interrupt the shape. A bold departure from a factory-stock 911.
Rauh-Welt Begriff took a stock Porsche 964 and reworked its bodywork into something genuinely confrontational, and the Jonsibal build is one of the studio's more distinctive individual creations.
A Sealed Resin Casting of an Extreme Widebody
GT Spirit casts this RWB build as a sealed, one-piece resin body, a construction well matched to the extreme, riveted-look fender flares that define an RWB conversion: the flared arches, splitter, and rear wing are all captured as continuous surfaces without a seam breaking their aggressive lines. The stance sits noticeably lower and wider than a stock 964, and the casting reflects that with a flatter, more purposeful profile than a standard Porsche replica. As a new, factory-packaged model, it arrives without the handling history a used piece would carry, with paint and detail exactly as produced.
A Tuner Special Outside the Factory Catalog
RWB builds are not factory Porsche products at all; each one is a bespoke aftermarket transformation, which means every individual car, including this Jonsibal build, has its own specific identity distinct from any catalog 911 variant. That individuality is exactly why RWB models appeal to a different segment of Porsche collector than a factory GT3 or Turbo would. At 1:18, the widebody stance and low ride height make this piece an immediate visual outlier next to a stock 964, and it works best displayed as a deliberate contrast rather than folded quietly into a standard Porsche lineup.
