According to Turner Motorsport's website solid mounts actually reduce mechanical stress on the chassis.
"The stock rubber bushings have serious drawbacks when used hard on the racetrack - they wear out quickly, and the flexible material allows extreme changes in alignment. Switching to solid bushings will eliminate the deflection and flex, keeping the suspension motions in their intended alignment and providing more feedback to the driver. On the E46 M3, solid bushings can help prevent rear subframe failure as the sheetmetal chassis will no longer flex along with the rubber mount.
Excessive movement here transfers to unwanted suspension motions elsewhere and is also a major contributor to failures in the rear floor sheetmetal.
While our Delrin-Aluminum subframe mounts conform to various racing series these all-aluminum mounts are the ultimate in reducing flex and deflection. The rubber stock mounts, and the Delrin mounts to a small degree, flex and deflect as various forces are applied throughout the subframe - on and off throttle loading, cornering on flat surfaces, bumpy surfaces, weight transfer, sticky race tires, etc. Too much flex from worn rubber mounts will transfer to flex where the subframe meets the chassis/floor. This is the primary cause for the infamous rear subframe failure. These fully solid aluminum mounts have absolutely zero flex to them so they will not contribute to rear subframe issues."
