Subframe Bushings and Differential Mounts

Transform your BMW's handling precision with Condor Speed Shop's rear subframe bushings. Engineered to eliminate unwanted movement, these premium bushings replace deteriorating factory rubber components to create a solid foundation for your rear suspension system.

Our bushings deliver immediate improvements in steering response, cornering stability, and overall performance. By reducing flex between the subframe and chassis, they create a more predictable driving experience that performs consistently whether laying down personal best lap times or attacking your favorite back roads. BMW enthusiasts will particularly appreciate how our stiffer bushings maintain rigidity, eliminating the squirm commonly experienced with factory rubber bushings.

Installing our rear subframe bushings is straightforward with basic mechanical knowledge and proper tools. Here are the steps:

1. Prepare the Vehicle: Lift and secure the vehicle on a lift or jack stands, then remove wheels and necessary suspension components.
2. Remove the Subframe: Support the subframe with a floor jack, disconnect all attached components, remove subframe mounting bolts, and carefully lower the subframe.
3. Extract Old Bushings: Remove old rubber bushings and clean mounting locations thoroughly.
4. Install New Bushings: Press in new Condor bushings, ensuring proper orientation and verifying fitment.
5. Reassemble and Reinstall: Lift the subframe back into position, install all mounting bolts, and torque to factory specifications.
6. Final Steps: Reinstall components and wheels, then get a professional alignment.

For detailed guidance, watch our step-by-step installation video below. While this is a manageable DIY project, we recommend having an alignment performed after installation to ensure optimal handling characteristics.

Q. Why use UHMW?

A. UHMW is a self-lubricating polymer and requires no additional lubrication. It is great as a bushing material because it absorbs some vibration and keeps its form. It is unlike polyurethane because it will never require lubrication and since it is machined from a solid piece, it will not come apart over time. It is very resistant to abrasion and will outlast the life of your car. We use UHMW on all our race cars and street cars.

Q. How do Condor bushings compare in noise and vibration to stock rubber?

A. You will see almost no increase in vibration when upgrading your control arm bushings, rear subframe bushings & rear trailing arm bushings. Almost always, the added NVH comes predominantly from transmission mounts. Some customers report that they feel no increase in NVH. Either way, once you feel the increase in performance you will realize Condor bushings are the perfect upgrade.

Q. Do I need to grease my bushings when I install them? Will they begin to squeak over time?

A. No, they will not squeak. This is the benefit of using UHMW. It is a self-lubricating polymer that requires no additional lubrication at install or over the lifetime of the product.

Q. Is it necessary to remove the entire subframe for installation?

A. Yes, removing the whole subframe is required for proper installation. While it might seem like extra work, this ensures correct fitment and allows you to inspect other suspension components while you're there.

Q. Will solid subframe bushings affect my alignment?

A. Any time you work with suspension components, including installing new subframe bushings, we recommend getting an alignment afterward. This ensures optimal handling characteristics and prevents uneven tire wear.

Q. How do I know if my stock rubber bushings need replacement?

A. Common signs include excessive rear-end movement during acceleration or braking, unusual clunking sounds from the rear suspension, and visible cracking or deterioration of the rubber bushings. If your BMW has over 60,000 miles, it's worth inspecting your stock rubber bushings for wear.

Q. Can I mix Condor subframe bushings with stock control arm bushings?

A. While you can mix them, we recommend upgrading your control arm bushings at the same time for the most consistent handling characteristics. This ensures all your suspension components work together optimally.
