UMI Performance Competition Coilover Kits

UMI Performance Competition coilover kits are built and proven to perform. Developed in cooperation with Sam Strano, the 14-time national SCCA autocross champion, these packages feature an AFCO-built aluminum body, plus monotube dampers with Strano-tuned valving that offers race-winning performance, while still providing an awesome street ride. They are rebound-adjustable, with a 40-position digressive rebound curve designed for competition body and weight transfer control. UMI Competiton coilover kits are available in front, rear, or complete (front and rear) packages. The kits include coilover shocks, springs with proper rates, fabricated bolt-in mounting brackets, hardware, and thrust bearings for each shock.

UMI Performance Competition coilover kits feature:

* UMI/Strano specific competition valving
* Front upper fabricated shock mount removes rust-prone GM rubber shock mount
* Front shocks assembled with progressive rate bump stops
* Double bearing shocks for crisp response, zero deflection, and high reliability
* 125 psi monotube provides quick reaction and fade-free performance
* Medium-firm fixed compression
* Balanced for use with UMI or Strano 35mm/22mm sway bars
* Ride height adjustment range from stock to 2 1/2 in. lowering
