Fine-tuning wheel offsets alters the stance of the 991 widebody chassis while slightly increasing track width to enhance lateral cornering stability. The 991 GT3 RS utilises centre-lock wheel hubs which differ from standard five-lug setups, but employing specialised hub-centric Wheel Spacers allows for precise offset adjustment where applicable. This ensures aftermarket or factory wheels sit perfectly flush with the wheel arches without compromising hub assembly integrity or suspension clearance.
