Cusco Lower Bar SUB-FRAME AP1 AP2 S2000 2000-2009 Honda S2000
The Cusco Lower Bar SUB-FRAME reinforces the rear subframe on Honda S2000 AP1 and AP2 models from 2000 to 2009. This chassis brace connects the lower control arm mounts to cut down flex and boost cornering stability. Drivers feel sharper handling precision and quicker suspension response right away during track or canyon runs.
Key Features
- Steel Tubing Construction: 50mm diameter high-tensile steel pipes welded to brace plates provide rigid support that fights chassis twist under hard cornering.
- 4-Point Mounting Design: Connects front and rear subframe sections for even reinforcement that keeps ride height stock while stiffening the platform.
- Bolt-On Installation: Bolts to factory mounting points using included hardware for easy setup in under one hour with basic tools.
- Powder Coated Finish: Black electro-deposition coating resists rust and road debris to maintain strength over years of use.
- S2000-Specific Engineering: Custom geometry preserves full suspension travel while firming the rear end for improved traction and turn-in.
Product Notes
- Confirm exhaust clearance before install as some aftermarket systems may require adjustment.
- Clean mounting surfaces thoroughly for secure bolting and optimal performance.
- Package measures 20 x 10 x 6 inches with foam inserts to prevent shipping damage.
Installation Notes
- Professional installation recommended.
- Raise vehicle securely on jack stands and remove undertray for access to subframe bolts.
- Compatible with OEM hardware torque to 45 ft-lbs on M12 bolts.

Chassis Bracing
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...

Suspension
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...
