The UMI Performance Stage 3.5 Handling Kit is engineered for the ultimate pro-touring experience, blending track-inspired performance with street-friendly comfort. This comprehensive package eliminates body roll, sharpens steering response, and significantly enhances overall vehicle stability, making it ideal for spirited driving, autocross, or track days.
Featuring a complete set of tubular upper and lower control arms equipped with low-deflection Delrin® bushings, this kit maximizes control. It includes a heavy-duty 1.25” front sway bar and an adjustable 1” rear sway bar to conquer body roll and allow for precise tuning. The 1” lowering springs provide an improved stance and a lower center of gravity for superior grip.
This kit also boasts tubular frame braces for increased chassis rigidity, new rear-end housing bushings to eliminate unwanted movement, and adjustable rear upper control arms for enhanced traction and pinion angle adjustment. Four RideTech HQ adjustable shocks are included, offering rebound tuning for a perfectly dialed-in ride quality.
Designed as a direct bolt-on for GM A-Body muscle cars, the Stage 3.5 kit requires no major modifications. It’s the perfect upgrade for aggressive street builds, weekend warriors, and autocross competitors seeking modern handling performance in a classic package.
