UMI Performance 93-02 GM F-Body Rear Lowering Springs, 1.5 Inch Drop, Pair

UMI Rear Lowering Springs for the 1993-2002 Camaro and Firebird, About 1.5 Inches of Drop

A pair of 200 lb/in linear rate rear coil springs that lower the back of a fourth generation F-body by roughly an inch and a half, wound from 9254 chrome silicon wire and made in Philipsburg, Pennsylvania. They suit pro-touring, autocross and fast street cars that want a level stance and better body control without moving to a coilover.

Key Features

• 200 lb/in linear spring rate for predictable, progressive-free rear body control.
• Approximately 1.5 inches of rear drop compared with a stock ride height car.
• Wound from 9254 chrome silicon wire, a high fatigue strength spring steel.
• Powder coated finish for corrosion protection.
• Works with standard replacement shocks, with Koni and Bilstein dampers recommended by UMI.
• Designed, manufactured and quality checked in Philipsburg, Pennsylvania.
• Supplied as a pair, two springs per box.

Fitment

The published fitment scope for this spring is unresolved at the manufacturer. UMI's description, feature copy, decision guide and FAQ all state 1993-2002 fourth generation only, while the same page's title and its structured fitment and platform attributes claim 1982-2002. This listing publishes the narrow, repeatedly stated 1993-2002 application. The broader 1982-2002 attribute claim exists but is not built into the fitment above, and third generation buyers should confirm with UMI before ordering.

UMI's 2024 panhard bar relocation kit page notes that lowering springs used with that kit also require the panhard bar lowering bracket, part 2063.

About UMI Performance

UMI Performance designs and manufactures chassis and suspension parts at 509 Hemlock Street in Philipsburg, Pennsylvania, using North American raw materials, laser-cut plate, CNC bending and precision welding. UMI sells direct and through dealers, ships most orders within three business days from Philipsburg, and publishes a printed installation sheet with each part number. Coverage runs two years from the original purchase date for the original purchaser, and UMI states it cannot guarantee compatibility with other manufacturers' components used alongside its parts.

FAQ

UMI publishes approximately 1.5 inches at the rear. UMI's own coil spring tech sheet also states that ride height is approximate and cannot be guaranteed because of the weight of the car, engine and accessories, so treat 1.5 inches as a target rather than a promise.

That document covers a family of UMI coil part numbers and describes the range as stock height, 1 inch and 2 inch lowering. It does not match the 1.5 inch figure on this product's own page. The product page figure is the one published for 2061R.

This listing is built for 1993-2002 Camaro and Firebird, which is the application UMI repeats throughout its description, decision guide and FAQ. UMI's structured attribute on the same page separately claims 1982-2002. That conflict is unresolved, so third generation owners should confirm with UMI first.

200 lb/in, linear, so the rate stays constant through the travel rather than ramping up.

Yes. UMI lists the contents as the 2061R 200 lb/in rear lowering spring, quantity two.

Not necessarily. UMI states these work with standard replacement shocks and recommends Koni or Bilstein for the best result on a lowered car.

UMI describes it as an easy to moderate DIY job taking one to two hours for the rear pair with basic hand tools, a floor jack and jack stands. Note that a chip elsewhere on UMI's page says easy DIY; the more conservative easy to moderate figure is used here.

UMI states that no specialised spring compressors are typically needed for the rear solid axle setup.

None are published for this part in any UMI document. Use the applicable General Motors factory service information for your model year for the shock and suspension fastener torques.

UMI names three groups: owners who want an ultra soft factory style ride, dedicated drag racers needing variable rate or drag launch springs, and cars that need a custom ride height only a coilover can deliver.

UMI markets these as race proven for pro-touring, autocross and high performance street use, while its warranty excludes damage from exceeding the design limits of the part. Both statements are UMI's, and they sit in tension; competition use is at the owner's risk.

UMI publishes a powder coat finish but never states the colour, so no colour is claimed on this listing.

Installation Instructions

1. Support the rear of the car safely on jack stands with the axle able to droop, following UMI's easy to moderate DIY outline.
2. Disconnect the lower shock mounts so the axle can be lowered enough to free the springs.
3. Remove the factory rear springs, noting the position of the spring isolators.
4. Fit the UMI springs and make sure the isolators are correctly seated during reassembly.
5. Reconnect the lower shock mounts and lower the vehicle onto its wheels.
6. Consult the applicable General Motors factory service information for your model year for shock and suspension fastener torque values, since UMI publishes none for this spring.
7. Ignore the orientation of the UMI sticker on the spring body; UMI states the stickers are applied in no particular orientation and may read upside down even when the spring is installed correctly.

UMI publishes no installation sheet specific to 2061R. A generic UMI coil spring installation and tech tips document lists 2061F/R among its part numbers, but most of its content covers A-body front and rear coils and does not apply to this F-body rear spring, so only its generally applicable statements are used here. UMI does not host this installation sheet on its own website. The document is UMI's own printed sheet, on UMI letterhead, served from a retailer's static PDF host, so treat it as a manufacturer document on a retailer host rather than a current UMI-hosted page.
