Roll Center Adjusters (RCAs)

Restore proper suspension geometry with roll center adjusters (RCAs) from SBX Performance. Lowering your vehicle often shifts the roll center below its optimal point, which can cause excessive body roll, poor steering response, and unpredictable handling. Roll center adjusters correct suspension geometry by repositioning the control arms, improving stability and cornering performance.

Our RCAs are CNC-machined from billet aluminum or high-strength steel, designed for precision fitment and durability under extreme load. By lifting the roll center closer to factory spec, these adjusters help sharpen turn-in, reduce understeer, and maximize grip — making them a must-have upgrade for lowered street cars and track builds alike.

Engineered for direct fitment on popular platforms like Honda, Acura, and other performance imports, our roll center adjusters pair perfectly with coilovers, sway bars, and camber kits for a balanced, predictable suspension setup.
