Product details
OVERVIEW
A replacement extended chassis brace for cars running Valvetronic Designs' larger G8x exhaust systems. The brace ties the rear subframe/mid-pipe mounting points together for added rigidity when a larger-diameter mid-pipe or axle-back is installed, and is sold separately here for owners who need a spare or replacement unit.
SPECS
- Purpose-built to accompany Valvetronic Designs' larger-diameter G8x exhaust systems
- Not compatible with the G87 M2, which uses a different chassis brace
