The Fox Body chassis is notorious for being relatively flimsy and easy to twist or even break depending on how much horsepower you're planning on putting down. This Exo Brace kit from Detroit Speed is aimed at reinforcing one of the most common failure points: your torque boxes and upper link mounts. These two components are known for cracking or completely ripping out on high horsepower applications, causing major chassis damage and posing as a huge safety concern. DSE's Exo Brace kit runs horizontally under your vehicle, connecting the torque boxes to your frame, floor pan, and to each other with a telescoping feature. Along with added strength, this brace also gives you an additional upper link adjustment hole to correct your lowered vehicle's instant center, but still retains compatibility with your factory links. This kit can be bolted on for applications under 400hp, or can be welded in for anyone making 400+hp.
