This Dinan front strut tower brace replaces the bare aluminum bar on the BMW E90, E92 and E93 M3 with a carbon fiber design. The brace uses aerospace-quality carbon fiber and aluminum, with black powder-coated forged aluminum ends that bolt into the car's existing strut tower mounts. Owners on user forums say a brace that ties the two front towers together sharpens steering response over stock, though several describe the gain as mild. The carbon weave is also matched to Dinan's High Flow carbon intake, so the engine bay looks like one cohesive build. Shoppers searching for an E9X M3 carbon strut brace, an S65 4.0L front brace, or M3 coilover clearance will find this part fits those needs.
The brace is listed for the S65 4.0L V8 M3 and works with any Dinan suspension system or with stock components, so it suits both street builds and track setups. Model years are the one detail to verify. The manufacturer's installation sheet lists the 2007–10 M3 (E90, E92, E93), while other catalogs list 2008–13, so confirm the application with the manufacturer before ordering. Owners on user forums also note that the M3 brace gives easier access to coilover top adjusters than the stock setup.

The manufacturer states the brace may be installed with any Dinan suspension system or with the stock components.
Owners on user forums describe firmer, more direct steering feel, though some call the change subtle. Expect refinement rather than a dramatic shift in handling.
Installation is a moderate DIY job that mostly involves removing and reinstalling the strut tower nuts and the stock brace. The manufacturer's install sheet walks through removing sections of the microfilter housing near the cowl, and it may require disconnecting the hood switch. The hardware kit supplies M8 bolts and lock nuts, so a basic socket set with a 13mm socket is the main tool you will need. Owners on user forums report that the swap itself took about 20 minutes once the stock brace was off, though one installer lost well over an hour searching for a dropped 13mm socket in the engine bay. Keep fasteners organized and check that the brace sits centered and level before final tightening.
