Whiteline 02-07 WRX / 03-07 Impreza NA / 04-07 STi / 93-00 Impreza NA Rear Front of rear diff suppor

If you're looking to firm up the rear end of your 1993-2007 Subaru Impreza, especially under acceleration or during hard gear changes, this differential mount bushing kit from Whiteline is a solid option. It's designed to reduce rear-end float and eliminate that clunk or slap you might feel from the drivetrain when you shift gears aggressively. This translates to more precise handling and a more connected feel from the rear of the car.

Whiteline uses a special synthetic elastomer for these bushings, which is resistant to oil, grease, ozone, and weathering, meaning they'll hold up well over time. The bushings are designed to work with your original factory mounts, and they come with internal grease reservoirs and a special molybdenum disulfide-based grease to keep friction managed and extend their life. This kit is often recommended for vehicles with bigger engines or for competition use like drag racing or circuit racing, where drivetrain stability is key. Just be aware that stiffening up these mounts can introduce a bit more vibration and noise into the cabin (NVH).
