Here’s the scenario: You’re launching your car hard, you do the one-two shift, let out the clutch, and WHAM! What was THAT?
Turns out, it’s the sound of the rear differential pounding against the chassis of the car, because the rear differential mount bushings are made of super-squishy rubber. Not only that, but they have holes in them, which makes them even less able to resist the intense power of the amazing Subaru engine.
These replacements from Turn-In Concepts are made of solid, and sturdy, urethane. Pick from two hardness levels — Comfort is good for most street cars, Race is for the hardest of the hard-core types.
Split bushing design means you can install these with hand tools, unlike other single-piece designs that demand a press.
Says Mach V Matt, “These really helped to tighten up the rear diff, making power transfer much more immediate. These go great with the Kartboy rear diff outrigger bushings and subframe lockdown bolts!”
