ISR Performance Solid Differential Mount Bushings - S14/S15 - Gold

ISR Performance is known for making parts that help tuners get the most out of their cars. These solid differential mount bushings are a prime example, designed to replace the stock rubber bushings in your S14 or S15. When you're pushing your car hard, especially on the track or during spirited driving, the stock rubber bushings can flex and allow the differential to move around more than you'd like. This can lead to sloppy shifts and a less connected feel.

By swapping to these solid, gold-colored bushings, you're locking down the differential much more firmly. This means less unwanted movement under acceleration and braking, which translates to a more direct and responsive drivetrain. Because they're solid, they won't degrade over time like rubber can, and they offer a consistent performance feel. They fit right into the factory differential mount location, making them a straightforward upgrade for anyone looking to firm up their rear end.
