Description
At PERON Automotive, we focus on upgrades that deliver real performance without unnecessary complexity. The MMR Performance Rear Subframe Bush Insert Kit is exactly that—an easy-to-install, high-impact suspension upgrade for your BMW F-Series (F2x & F3x).
The factory rear subframe mounts allow for more movement than ideal, especially during hard cornering. This can lead to inconsistent handling and compromised suspension geometry. MMR’s precision-machined inserts limit that movement, sharpening response and improving rear-end stability—without the need for harsh solid mounts.
Installation is quick—under an hour—and completely reversible, making it a perfect upgrade for daily drivers and performance builds alike.
