Why upgrade your M3 rear cradle mounts

• Pin-point handling - limits rear carrier flex for cleaner turn-in and consistent chassis behaviour.
• Better traction and braking - keeps alignment steadier so the tyres can work harder.
• More even tyre wear - helps maintain geometry for longer.
• Long-lasting compound - polyurethane resists oil, road grime and ageing far better than rubber.
• Ideal for fast-road and track days - an essential S65 M3 chassis refresh.

Tired rubber mounts can cause a vague rear end, knocks over bumps and instability when loaded up in bends. Swapping to Powerflex PFR5-422P tightens the rear cradle so your E90, E92 or E93 M3 feels more connected without unwanted harshness. We have fitted these on our own cars and for many customers with consistently excellent feedback on the improved confidence and control.
