This Sparco 600 Series passenger-side seat base (600SB436L) offers a direct bolt-in solution engineered specifically for all R34 Skyline models. It mounts cleanly to the factory floor mounting points with no cutting or welding required, creating a strong, flat platform with pre-drilled holes that align perfectly with Sparco seats.\u003cbr\u003eBuilt from heavy 3\/16-inch steel, the wide base allows for the lowest possible seating position when side-mounted, significantly improving center of gravity and enhancing driving dynamics on both street and track. When combined with the SPA00493 track set and SPA50001ZN hardware kit, it provides smooth forward-and-back adjustment while keeping the entire system simple and secure. The result is a transformed passenger cockpit that feels planted, supportive, and fully prepared for performance driving.\u003cbr\u003eDesigned exclusively for Sparco seats, this passenger-side base delivers professional-grade strength and precise fitment that outperforms generic adapters, giving R34 Skyline owners the confidence to complete a factory-quality racing seat installation the right way. \u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eDirect bolt-in fitment for Nissan Skyline models (R34 generation) using original factory seat mounting points — no cutting or welding required\u003c\/li\u003e\n\u003cli\u003eSpecifically engineered for the passenger side (left side) seat position\u003c\/li\u003e\n\u003cli\u003eHeavy-duty 3\/16\" steel construction with a wide platform for the lowest possible seating position\u003c\/li\u003e\n\u003cli\u003eAllows side-mount drilling for optimal low hip point and improved center of gravity\u003c\/li\u003e\n\u003cli\u003eRequires one Sparco Track Set (SPA00493) per seat for smooth forward and backward adjustment\u003c\/li\u003e\n\u003cli\u003eRequires appropriate Sparco hardware kit (SPA50001ZN bottom-mount recommended for street seats or side-mount for competition seats)\u003c\/li\u003e\n\u003cli\u003eDesigned exclusively for Sparco seats — pre-drilled holes match Sparco bolt pattern (not guaranteed for Recaro or other brands without adapters)\u003c\/li\u003e\n\u003cli\u003eProfessional installation strongly recommended for correct torque specs, seat alignment, belt routing, and safety compliance\u003c\/li\u003e\n\u003cli\u003eDelivers a strong, flat mounting surface that transforms your R34 cockpit for both street comfort and track performance\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Sparco","offers":[{"title":"Default Title","offer_id":51639504503105,"sku":"spa600SB436L","price":199.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1992\/7247\/files\/600SB119L.jpg?v=1776365299","url":"https:\/\/tfaspeed.com\/products\/sparco-passenger-side-seat-base-for-nissan-skyline-r34","provider":"Terra Firma Automotive","version":"1.0","type":"link"}
