BOOMBA RACING is proud to announce our new rear motor mount (RMM) for the Fiesta ST!

This direct bolt-on mount and bracket combine to replace the rear-lower engine torque mount, also known as a torque damper, significantly improving the vehicle’s traction and shifting response by reducing excessive engine flex. Wheel-hop during hard launches are also completely eliminated thanks to these mounts. Boomba Racing mounts are machined from high quality aircraft grade billet aluminum for strength, durability and looks. Inside each mount you’ll also find solid polyurethane bushings with the rigidity carefully chosen to optimize vehicle stability while also minimizing excessive vibration transfer from the motor to the body.


Installation is simple, does not require engine support and utilizes all OEM hardware. Mounts are available in Natural Aluminum finish as well as Red, Black & Blue anodized.

MSRP: $155.00

Looks good, but probably will be a little harsher then cobbs imo and since they we're first to market with a bolt on rmm. I would've undercut their price point by at least 5% to encourage/sway new customers. Cool to see more options though.

Very pretty.. Any differences in terms of install to the other mount(s) on the market? e.g. removing brackets, etc?

I can't imagine how the installation is any different. It should be easier since you don't have to hammer out the mounting plate from the stock one to be re-used. This one comes with a beefier one. It's literally a bolt-on product. I'm really intrigued by the symmetrical design.

^ Exactly. Biggest difference is that we chose to replace the entire unit, bracket included. All CNC machined out of billet aluminum.

Just curious about the design. What was the benefit to making both bushings the same size, as opposed to stock where there is a larger bushing toward the driver and a smaller bushing on the engine side?

We've designed it that was in order to evenly distribute load & stress, which maximizes performance!

All 4 colors are in stock and ready to ship! This RMM greatly reduces engine flex, resulting in complete elimination of wheel hop during launches and and contributing to much more solid handling!
