The MMX Performance Rear Differential Billet Front Cradle Mount Set is a direct replacement for the factory front differential mount on the BMW G87 M2, G80 M3, G81 M3 Touring, G82 M4 and G83 M4. CNC machined from 6061-T6 billet aluminum, it removes the compliance of the stock rubber-isolated cradle so the differential stays located under hard acceleration and changing loads, which tightens rear-end response and sharpens driveline feel on the S58-powered G8X chassis.
The cradle is height adjustable. Installed as supplied it holds the differential at factory height; paired with the MMX Rear Differential Raised Poly Bush (MMR55-1605, sold separately) it raises the differential 10mm, which on lowered cars restores driveshaft and axle geometry and reduces CV joint operating angles. It can also be expanded into a four-point differential mounting setup with the MMX Dual Differential Mount (MMR55-1606, sold separately) and is compatible with the MMX G8X Billet High-Capacity Differential Oil Pan and Rear Differential Output Shaft Heat Shield Set. Designed and engineered in the UK and track tested in motorsport conditions, it uses the factory mounting points and installs with no cutting, drilling or permanent modification, suited to both street and track use.
