Cobb and Boomba RMM Review

[Grendlehop18]

After ~1200 miles with all 3 mounts upgraded, they're nicely broken in. For me, I definitely feel less and less NVH due to warmer ambient temps and engine heat warming them up. Although, Phx and summertime are on the extreme high end of the spectrum. Hypothetically, if I was forced to go back to all oem mounts with the sloppy shift feel and rubber band power delivery, I'd sell the car.
