The OVERTAKE Drivetrain Bushing Bundle puts our three driveline bushing upgrades for the Subaru 2008-2027 WRX and 2008-2021 STI in one box: the Rear Differential Bushing Insert Full Kit, the Transmission Crossmember Bushing Kit, and the Transmission Mount Insert. All three are polyurethane, and together they firm up the soft factory rubber at the transmission and the rear diff.  If the shifter feels vague and the car rocks when you let the clutch out, you are feeling factory rubber move.

Subaru mounts the transmission and rear differential in soft, voided rubber to keep noise and vibration out of the cabin, and for a quiet commute that works. Push the car and that same rubber lets the gearbox and the diff shift around under load. The OVERTAKE Drivetrain Bushing Bundle is built for the manual transmission 2008-2027 WRX and 2008-2021 STI to tie down all three spots in one go. You are under the car once, and the whole driveline tightens up together.

What You'll Feel:

With the transmission and rear diff both held in place, the change shows up at the lever, the pedal, and the seat:

• More direct gear changes
• Less driveline slop on and off throttle
• Steadier clutch take-up
• Rear end that stays planted under load
• A drivetrain that feels connected

Features:

• 80A durometer polyurethane at the rear differential and transmission crossmember
• Molded 65A polyurethane transmission mount insert that fills the factory mount voids
• Rear diff inserts slip over the OEM bushings, crossmember bushings replace OEM with new stainless steel sleeves
  
• No cutting, drilling, or permanent modifications

The Details:

Most owners chase drivetrain slop on a Subaru one bushing at a time, and each one helps. This bundle covers the transmission crossmember, the transmission mount, and the rear differential in a single order. The crossmember and rear diff pieces are 80A polyurethane, and the mount insert is a softer 65A so transmission whine stays out of the cabin. The only part that changes between the two options is the mount insert, because the 2008-2021 WRX mount has three voids and the STI and 2022-2027 WRX mount has two. Figure about 20 minutes for the rear diff inserts, 60 for the crossmember bushings, and 20 to 30 for the mount insert, all with basic hand tools. Expect a little more NVH, and most owners take that trade for the added feedback.

Applications:

• 2008-2021 Subaru WRX
• 2022-2027 Subaru WRX
• 2008-2021 Subaru STI
