Cusco Rear Pillowball Upper Mounts for Select 2001-2007 Subaru Impreza WRX/STI (Non-OEM Spring Only) 658 420 A
This product will be available for sale in 2 weeks, but you can pre-order now to receive 10% discount!
Fits select 2001-2007 Subaru Impreza, WRX, and STI models.
Cusco Pillowball Upper Mounts are designed to replace the compliant factory rubber mounts, providing a rigid connection between the suspension and the chassis. This upgrade improves steering response and provides more precise feedback by eliminating the deflection found in OEM bushings, ensuring that your dampers and springs function exactly as intended during high-performance driving.
Note: These rear mounts are specifically designed for use with aftermarket coilovers or small-diameter race springs. They are not compatible with the original equipment (OEM) large-diameter spring setup.
- Manufacturer Part Number: 658 420 A
- Position: Rear
- Bearing Type: High-precision pillowball
- Construction: Durable aluminum plate for weight savings and rigidity
- Fitment Note: Requires aftermarket coilover-style springs; will not fit OEM big spring setup
