Description
The E82, E90 and E92 all share the same subframe bushings, which wear pretty quickly. The factory bushing is made in rubber, which allows a small amount of movement in order to provide a comfortable ride. As rubber bushings lose their strength over time, the axle carrier starts to move more and more. You will slowly lose feedback from the rear-end. Worn subframe bushings increases wear on the other suspension components. When the subframe moves excessively, it puts an abnormal amount of stress on the control arms and their bushings. Bad subrame bushings will also cause alignment issues, as the axle carrier refuses to stay put.
Do I need new subframe bushings?
If you plan on enjoying your car, then we recommend it. Upgrading the subframe bushings is benefical to everyone who owns these BMW. The factory subframe bushings are so bad, daily driving is enough to wear them down. It is one of the most profitable maintenance you can give your BMW.
Why Tech-53
Our latest design allows you to raise your subframe or retain its original position. Installing this kit without the top bushings allows you to bolt the subframe directly on the chassis, half an inch higher than the original position. If you install everything this kit provides, it retains the original subframe height.
What’s are the benefits of a raised subframe?
•CV Joints
By raising the subframe closer to the body, the CV joint angle is optimized. On a lowered car, the CV joints often operate at steeper angles, which can cause additional stress and wear. With the raised subframe, the CV joints return to a more natural angle, reducing strain on the joints. This reduces the likelihood of premature wear and failure.
•Control Arms
The control arms also benefit from the raised subframe. On a lowered car, the control arm angles can become less than ideal, affecting suspension geometry. Raising the subframe helps correct the control arm angles, ensuring that the suspension maintains optimal geometry. This leads to improved handling characteristics, especially during cornering.
What’s included?
This kit comes with four Delrin subframe bushings, four 6061-T6 aluminium inner sleeves and four 6061-T6 aluminium top bushings.
