Progress Tech 02-06 Acura RSX/01-05 Honda Civic Rear Brace Assembly

Chassis bracing reduces structural flex in unibody and body-on-frame vehicles, improving handling precision, steering response, and suspension geometry consistency under cornering loads. Front strut braces, rear chassis braces, and underbody reinforcement kits all target different flex points depending on the vehicle and build goals. Popular Upgrades The most popular chassis bracing upgrades include front upper strut tower bars for reduced front-end flex, rear lower chassis braces for improved rear subframe rigidity, underbody X-braces and torque boxes for full chassis stiffening, and sway bar end link braces for more predictable corner entry behavior. Many enthusiasts pair front and rear bracing for the greatest improvement in overall chassis feel. What does chassis bracing actually do for handling? Chassis flex causes subtle but measurable changes in suspension geometry during cornering and acceleration. Reducing flex with bracing keeps the suspension working as designed, which tr...

Aftermarket suspension systems improve handling, ride quality, and ride height adjustment beyond what the factory suspension provides. From lowering springs and coilover kits for sport handling to lift kits and leveling kits for truck and SUV off-road capability, quality suspension components transform how a vehicle rides and handles. Popular Suspension Upgrades Popular suspension upgrades include coilover kits for adjustable ride height and damping, sport lowering springs for improved handling and reduced body roll, performance shock absorbers and strut assemblies, sway bar and end link upgrade kits, subframe brace kits, and complete suspension packages for lifted trucks and off-road SUVs. Alignment kits including camber bolts and camber arms are also frequently ordered after ride height changes. What is the difference between coilovers and lowering springs? Coilovers are complete shock and spring assemblies with adjustable ride height set by threading the spring perch on the shock...
