Torque Solution TS-GR-722 Solid Billet Differential Bushing Kit Supra A90 BMW Z4

Vehicle Fitment

• 2020-2026 Toyota GR Supra MKV (A90 / A91) - all trims
• 2019-2026 BMW Z4 G29 - all trims

Fitment Notes

• Direct replacement for OEM rubber differential mounting bushings - no subframe modification required
• Covers both the front differential pumpkin bushings and the rear subframe differential mounting bushing - full differential mounting position is addressed
• Solid billet aluminum construction increases NVH (noise/vibration/harshness) compared to OEM rubber; best suited for performance street, track, and competition use
• Professional installation recommended

Features

• Eliminates OEM rubber bushing deflection - holds the differential rigidly in position for consistent rear suspension geometry under hard acceleration, braking, and cornering
• Reduces wheel hop and drive shaft / half shaft stress caused by differential movement under load
• Improves power transfer to the rear wheels - more direct, consistent drive feel especially on launches and hard acceleration
• CNC machined 6061-T6 solid billet aluminum - will not crack, tear, or degrade like OEM rubber bushings under sustained high-load or track use
• Black anodized finish with Torque Solution laser engraving for a clean, show-quality appearance
• Backed by Torque Solution's Limited Lifetime Warranty

Product Description

The Torque Solution Solid Billet Differential Bushing Kit (TS-GR-722) replaces the OEM rubber differential mounting bushings in the 2020+ Toyota GR Supra MKV (A90/A91) and 2019+ BMW Z4 G29 with precision CNC machined 6061-T6 solid billet aluminum units. The factory rubber bushings are known to deflect, crack, and tear under hard driving and sustained track use - allowing the differential to shift position under load, which causes wheel hop, inconsistent handling, drive shaft stress, and poor power transfer. Eliminating this deflection with solid billet aluminum holds the differential firmly in place for predictable, consistent rear-end behavior under all driving conditions.

The kit addresses both the front differential pumpkin mounting bushings and the rear subframe mounting bushing for a complete solution. Solid billet construction will not wear out or require replacement like rubber or polyurethane alternatives. Some increase in NVH is expected compared to OEM rubber - this kit is best suited for performance street, track day, and competition builds where ride comfort is secondary to handling precision and drivetrain integrity.
