Dinan 10mm Rear Upper Shock Mount Kit (RSM) for BMW E82 E90 E92 E93 (E8X E9X) - 1 Series, 3 Series, M3 - 2006-2013 | Direct Bolt-On Rear Shock Top Mount Upgrade 135i 335i

Transform the rear end of your E8x and E9x with this Dinan Rear Upper Shock Mount upgrade, adding 10 mm of extra damper stroke for a calmer, more controlled ride on British roads. Expect smoother bump absorption, crisper response and a more composed rear axle without altering stance or geometry. Ideal for daily drivers, spirited B-road use and fast-road builds looking for a smarter suspension tweak rather than a full overhaul.

Designed by Dinan specifically for BMW 1 Series, 3 Series and M3 platforms, these rear damper top mounts retain factory pick-up points and install with a straightforward bolt-on process. No alignment is required after fitting. Works with OE dampers and most performance shocks that accept factory-style upper hardware, including Dinan D140-0945. Not suitable for Dinan D140-0946 units that feature external adjustment at the top.
