Sparco's vehicle-specific custom seat subframes have been designed to bolt directly onto specific vehicles without the need for additional modifications. They can be used with Sparco seat slides or in some cases (where noted) they can be used with the original slides. The Sparco seat is then easily bolted onto the guides for quick and hassle-free installation. Check the specific assembly notes for slides or other accessories that may be required. Note: We only recommend using Sparco seats with Sparco subframes. If used with non-Sparco seats, additional modifications and/or adaptations may be required. Bolt Pattern (Center to Center): Width: 345mm Depth (Front to Back): 270mm
