Drivers upgrading their Nissan Skyline R32 or R33 know that a proper racing seat installation starts with a rock-solid foundation. This Sparco 600 Series passenger-side seat base bracket delivers a direct, bolt-in solution engineered specifically for every R32 and R33 Skyline variant, from GT to GTS to GTR. It mounts cleanly to the factory floor points without any cutting or welding, creating a strong, flat platform that accepts Sparco seats with perfect alignment and pre-drilled holes.
Constructed from heavy 3/16-inch steel, the wide base allows for the lowest possible seating position when side-mounted, improving center of gravity and driving dynamics on both street and track. Combined with the required Sparco track set and hardware kit, it enables smooth forward-and-back adjustment while maintaining factory-like simplicity. The result is a transformed cockpit that feels planted, supportive, and ready for serious performance driving.
Designed exclusively for Sparco seats, this passenger-side base ensures precise fitment and professional-grade strength that outperforms makeshift adapters or generic brackets, giving R32 and R33 owners the confidence to install high-performance seating the right way.
