CPM's Aluminum Front Strut Brace Bolts Into the G8X M2, M3 and M4 Using Factory Points

Some of the best mods are boring to look at and quick to install. CPM's new front upper strut brace for BMW's G8X M cars is one of them. PASMAG reported on August 28 that the brace is now available for the G8X platform, including the M2, M3 and M4, through Mackin Industries.

It is made of lightweight aluminum and attaches using the car's existing mounting points, which keeps installation straightforward. CPM's goal is to add front-end chassis rigidity, which the company says should give sharper steering response and better stability in corners and at higher speeds.

What a strut brace actually does

A front strut brace ties the tops of the two front suspension towers together. Under hard cornering, those towers try to flex relative to each other, which changes the suspension geometry a little and blurs the steering. A brace stiffens that connection so the front suspension stays where the engineers put it. On a modern car with a stiff structure, the change is subtle, but owners who spend time at the track tend to notice it in quick direction changes.

The G8X cars are heavy, powerful and very capable, and a lot of them are now seeing HPDE weekends and time attack events. Front-end response is one of the most common things owners want to sharpen, and a bolt-in brace is an easy first step before getting into bushings and alignment.

Who it is for

This is a part for the M car owner who has already done tires and pads and wants the front end to feel a little more locked down at the track, without anything that changes ride comfort. Because it uses factory mounting points, it is also easy to remove when the car is sold, which matters on cars this expensive. CPM's parts are distributed in North America by Mackin Industries.

Weight, price and part number were not included in PASMAG's report. The hero photo of an installed brace was supplied by Win Motoring, PASMAG noted, with product photos from Mackin.
