Fall-Line Motorsports Chromoly Rear Strut Brace - BMW E46 M3
The E46 M3 rear end flexes more than most owners realize, and that flex shows up as vague rear grip mid-corner. The Fall-Line Motorsports Chromoly Rear Strut Brace ties the rear strut towers together, cutting chassis flex and body roll so the rear suspension does its job.
It is one of the simplest ways to make an E46 M3 feel tighter.
4130 Chromoly with a Fixed Center Bar
Built from AISI 4130 chromoly steel and CNC machined to factory BMW specifications. The center cross bar is not removable, which maximizes stiffness. Choose Raw Metal or Black Texture, a powder coat that matches the OE wrinkle finish. Made in the USA.
