I decided not to go with the Sparco seat base after-all. They sell for $260/pair new, asking $225/pair, shipped ($210 if you pick-up in Maryland.) Sparco Seat Bases utilize the factory seat mounts on your vehicle's floor and provide a flat surface for mounting your Sparco seat. All seat bases are vehicle specific and provide a 100% bolt-in installation. These fit 2002-2006 MINI (all models). New, never installed. Either side for $120/each. PM if interested or if you have questions. Paypal preferred. Cheers.
