Progress Technology USA is a California-based suspension specialist with over 20 years of North American aftermarket heritage. Renowned for pioneering progressive-rate sway bars, Progress offers a full suite of chassis upgrades—including sway bars, end links, adjustable control arms, coilover kits, and lowering springs—designed to sharpen handling without compromising ride comfort.

Progressive-Rate Sway Bars: Their signature hollow-bar design uses varying wall-thickness to deliver a linear transition from compliant street behavior to firm, roll-control under cornering—so Civic, Integra, and S2000 owners enjoy both smooth daily manners and confident track performance.

Adjustable Control Arms & End Links: CNC-machined from aircraft-grade aluminum, these arms restore correct suspension geometry after lowering, while Heim-joint end links provide precise anti-roll-bar articulation on both Honda and Toyota platforms (including the 86/BRZ).

Coilovers & Springs: Progress’s coilover kits feature independent compression-and-rebound damping adjustments, pillow-ball top mounts, and incremental ride-height settings. Their progressive-rate lowering springs pair factory-ride quality with a 25–35 mm drop and improved mid-corner support.

All Progress components are CAD-engineered, powder-coated for corrosion resistance, and bench-tested to ensure direct-fit installation and long-term durability. Whether fine-tuning a lowered Civic or dialing in a GR 86 track setup, Progress Technology USA delivers the handling precision and everyday comfort that enthusiasts demand.
