The RONGINEER M3 Rear Body Brace provides an effective and efficient way to increase
the torsional stiffness of the rear body. The multiple attachment points and the truss design of the brace provide a higher
level of support and stiffness to the rear body compared with a simple strut brace spanning the shock towers. In essence
the brace forms a second bulkhead behind the rear compartment bulkhead. The truss design of the brace provides stiffness
in the support plane at a minimum of weight – the brace only weighs 4 pounds! The floor attachment points of the brace
provide additional support to the anti-roll bar support brackets mounted underneath the floor. These brackets support
the original anti-roll bar brackets that are known to be failure prone when stiffer anti-roll bars are installed. Vehicles
with suspensions tuned for track, auto-x or street will benefit.
The M3 Rear Body Brace fits E30 325i models when the ballast pad on the floor is trimmed or removed.
