Chassis flex on unibody cars like the Mustang has always been a problem, especially on convertibles, and it gets even worse when you modify the engine to extract more horsepower and bolt on a set of big sticky meats. The solution to chassis flex is to bolt or weld on a set of Gripp subframe connectors. These connectors are constructed from heavy-duty boxed steel like you would find on the best full-frame vehicles, and installing them will give your unibody full-frame like strength and rigidity. With these connectors installed, instead of chassis flex you'll get tire hook-up for better acceleration and traction in the corners for precision steering.

Featuring precision welds and die-stamped brackets, each connector is fully sealed and powdercoated gloss gray metallic for durability and maximum visual appeal. Each set comes complete with hardware for a bolt-on installation, but welding the connectors in place is recommended for maximum strength. These subframes are available in a version that includes "seat-mounting brackets", which reinforce the flex-prone floor pan under the front seats.

The Gripp Subframe Connector Kit is backed by a 1-year limited warranty against defects in materials or workmanship, as long as the product was installed according to BBK guidelines.
