• The rear brackets are bolted directly to the outside of the differential
• No resealing of the differential is required, as installation is done from the outside
• Can reduce wheel hop, improve traction, and optimize power transfer under load
• Designed for high loads in motorsport, on the racetrack, and in drifting

Compatibility

Suitable for BMW E46 and BMW E85 non-M models with an 188K differential.

The kit is compatible with both the standard differential cover and the ribbed BMW Z4 differential cover.

Important installation note: For installation, the original rear differential mounting point on the rear subframe must be removed. The new mounting brackets must be professionally welded to the subframe. Installation must therefore be carried out by appropriately qualified professional personnel.

Please check compatibility with your vehicle, the installed differential, and any existing modifications before purchase.

Not compatible with the BMW E46 M3.

Intended Use

Exclusively for motorsport vehicles, track tools, Nürburgring
