Sparco Base BMW 3 Series 75-83 Lft

The Sparco Base for BMW 3 Series 75-83 provides a robust and flex-free mounting solution for Sparco seats. Constructed from 3/16 inch thick steel, this seat base ensures durability and strength for racing and performance applications. It uses the factory seat mounts on your vehicle's floor for a 100% bolt-in installation, maintaining a secure and stable fit.

Designed specifically for the left side of BMW E21 chassis models from 1975 to 1983, this base features a wide metal platform that allows for custom mounting of side mounts directly to the base, which is ideal for race vehicles seeking the lowest possible seat position (custom drilling required).
