BimmerWorld Race Hybrid Subframe Bushing Set - F22, F30, F32

Mostly-solid rear subframe mounts for F22 2-series, F30 3-series, F32 4-series. We use a large aluminum main mount with a Delrin sleeve for a correct and precise fit into the F3X rear subframe.

Solid Delrin and aluminum subframe mounts for F22, F30, and F32 will give your rear suspension the rigidity it desperately needs. Since everything in the rear suspension is tied to the subframe, it only makes sense that this should be as rigid as possible. If the subframe moves, so do all of your control arms, bushings, alignment, and even the output shafts. There's a reason why BMW M stopped using rubber subframe mounts in production street cars. What you will notice is that the rear suspension feels planted and more stable - which is exactly what you want!

The Bimmerworld F30/F32 solid subframe mounts are direct replacements for the stock rubber mounts. They form a rigid connection between the subframe and the rear chassis. We previously ran Delrin mounts in our IMSA race cars and other series but this latest design is a hybrid Delrin and aluminum. Full aluminum is a challenge due to the design of the F3X rear subframe with its slotted tabs that lock in the stock bushing. The Delrin material offers some distortion as the bushing is installed while still being a very solid material (much more than urethane). The Delrin can absorb some vibration as well, although we still would discourage using these on a daily street car.

Our solid subframe mounts are CNC machined from Delrin and premium alloy and hard anodized for extended protection. We have designed our bushings with relief areas to properly accommodate the tabs on the inside of the subframe.

Subframe mount upgrade fits all F22 2-series, F30 3-series, and F32 4-series, including Xi cars. Not for F87 M2, F80 M3, or F82 M4 which have a rigidly-mounted subframe from the factory.

Made in USA.
