Product Description
Solid Delrin and aluminum subframe mounts for all F30 3-series, and F32 4-series 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.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. The Delrin material satisfies class rules in IMSA and other series that prohibit fully solid mounts. These were developed especially for our IMSA 328i race cars. Most of the NVH is absorbed through other rubber bushings in the suspension. Customers who use these on the street have not reported any additional ride harshness with solid subframe mounts. What you will notice is that the rear suspension feels planted and more stable - which is exactly what you want!
Our solid subframe mounts are CNC machined from Delrin and premium alloy and hard anodized for extended protection. Developed and tested on the Bimmerworld F30 328i race cars and Made in the USA.
Fits all 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.
