Application Guide:

Drag Racing - 110lb Spring
  • Drag Racing applications are available with a 110lb spring in conjunction with the -2" to -3" ride height or the -1" to +1" ride height. This package is best utilized on a lightened car. We recommend taking measurements for a fitment based on the desired ride height and tire combination.
Street Performance - 150lb Spring
  • Street applications are available with a 150lb spring in conjunction with the -2" to -3" ride height or the -1" to +1" ride height. We recommend taking measurements for a fitment based on the desired ride height and tire combination.
AutoX / Road Racing - 225 Spring
  • AutoX / Road Racing applications are available with a 225lb spring in conjunction with the -2" to -3" ride height. We recommend taking measurements for a fitment based on the desired ride height and tire combination.

Drag Racing Application

Spanner Wrench & Thrust Bearing Kit: Spanner wrench tool is used to adjust vehicle height while shock stays mounted. This wrench is needed to make height adjustments. The thrust bearing kit is designed to be placed between the spring and the spring seat attached to the shock. This makes for easier adjustments since the spring seat is rotating on a bearing. This kit is recommended for easier adjustments but is not needed to complete the installation. We do not recommend adjusting height on the car without a thrust bearing kit.

  • Pontiac Bonneville 1982-1986
  • Pontiac Grand Prix 1978-1987
Installation & Fitment Notes:
  • UMI recommends installing the 3054 bracket kit, mocking up the ride height as desired, then purchasing the correct length shocks.
  • Rear shocks may not clear all exhaust systems. UMI is not responsible for exhaust clearance issues.
  • These brackets are engineered specifically to pair with Quick Performance adjustable lower control arm brackets. The 3054 will also fit on the Quick Performance single hole non-adjustable bracket but will not have the ability to adjust the lower control arms.

Who is UMI Performance?

UMI Performance is an aftermarket company that specializes in building high-quality suspension parts. But before they were known as a suspension manufacturer, they manufactured precision parts for major brands such as Corning Asahi, Sony, and Bell+Howell. They may have shifted industries, but their dedication to creating quality products has remained the same.

Quality Products Made In The USA

All of their products are made in-house, which allows them to control every aspect of their products. 100% made in the USA, they can maintain their high standards and create suspension parts that can tackle any street, whether it be the fast corners of a race track or the bumpy road to your grocery store.

Parts Bred From The Racetrack

UMI Performance actively participates in various racing disciplines since most of their product engineers and sales team are racers. Because of this, they can test their products through real-life racing scenarios, which helps them gather data that can help improve their products.

Easy To Install Parts

Each product is designed to replace factory-installed parts without any significant modification. It is carefully measured to ensure that it would fit perfectly into the vehicle and comes with a step-by-step instructional manual, giving their customers a hassle-free installation experience.
