Product Details

These MTS Technik Street Series coilovers fit the 1978-1981 BMW 733i (E23). MTS coilovers let you adjust the suspension height to your preference and to road conditions. The firmer suspension makes the car more predictable to drive. With these MTS E23 733i coilovers you can reset the ride height when you swap between larger summer wheels and smaller winter wheels.

Standard Features

  • The Street Series is the default setup MTS engineers suggest, with a wide range of lowering and a balance of comfort and stiffness.
