Machined from billet 6061-T6 aluminium, it provides an additional \u003cstrong\u003e15mm of exhaust clearance\u003c\/strong\u003e while maintaining original ground clearance, and stiffens the platform in the process.\u003c\/p\u003e\n\u003chr\u003e\n\u003ch3\u003eRoom For A Proper Exhaust\u003c\/h3\u003e\n\u003cp\u003eLarger diameter aftermarket exhaust systems on a G8X commonly foul the standard underbody brace. Cutting the brace weakens it and removing it costs rigidity, so neither is a good answer. The MMX brace is designed around the exhaust path from the start, freeing 15mm of clearance without sitting any lower than the original component.\u003c\/p\u003e\n\u003chr\u003e\n\u003ch3\u003eStiffer Than The Part It Replaces\u003c\/h3\u003e\n\u003cp\u003eMachining from billet allows material to be placed where load is actually carried. The MMX brace is consequently stiffer than the factory item, which tightens the response of the platform under steering input and load transfer. On a car as capable as a G80 or G82, small gains in structural rigidity are felt directly through the steering.\u003c\/p\u003e\n\u003chr\u003e\n\u003ch3\u003eStraightforward Installation\u003c\/h3\u003e\n\u003cp\u003eThe brace uses the standard mounting points and requires no cutting, drilling or modification of any kind.
