034Motorsport Transmission/Differential Mounts, Early Audi, Motorsport Spec, Billet Aluminum & Delrin

034Motorsport's Motorsport Spec Differential/Transmission Mounts suit early Audi models, including the B3 80, 90 and Coupe quattro, the Ur-Quattro, the 4000 and 5000, the 100 and 200, and the S2 and RS2. Machined from billet aluminium and Delrin, they are a drop-in replacement for the factory mounts and come with new high-grade metric hardware. 034Motorsport says the result is a locked-down drivetrain, solid shifting and virtually no wheel hop, but warns of a noticeable rise in cabin noise, vibration and harshness and suggests its Density Line mounts for street cars. Mounts are sold individually with two needed per car, and on later B4 cars that use B4/B5-style rear differential mounts they replace the transmission mounts only.
