Team Z Motorsports ’79-’93 Mustang Stock Location Rear Drag Springs

The Fox-chassis Mustang boasts one of the most successful factory-designed rear suspension systems for drag racing that has ever graced the pavement. The factory coil springs are acceptable, but not ideal for a racing application, and that’s where Dave Zimmerman and the crew at Team Z Motorsports comes into the picture. 

Zimmerman has been designing suspension parts for the Mustang for over a decade now, and his front K-member kits and rear suspension kits are found on some of the quickest and fastest Mustangs in the small-tire racing scene.

“For years, I’ve been advocating that if someone wants to stick with the stock rear suspension design, that they take a factory V8 spring and cut off one coil – and that’s been good enough. Some of the spring kits in the market have left and right rear springs that have different rates, but those were designed years ago when people weren’t using anti-roll bars. We found the cut-coil V8 spring to work most effectively with the anti-roll bar, but most people couldn’t find a set of stock springs that weren’t worn out,” he explains.

So what did he do? He decided to design a spring that would work properly and not break the bank for his customers.

These made-in-the-USA springs work in the stock location and are designed to replace the stock springs on a 1979-’93 Mustang. They’ll lower the ride height approximately 1.5 to 2 inches depending on vehicle weight, and will drastically improve the geometry and 60-foot times.

Over ten years of Team Z’s research and development have been used to make a spring package that simply works.

A slightly-progressive rate along with a proprietary blend of spring steel (like that used in racing valve springs) combines to keep the tires planted downtrack. 

“We found that these springs worked best with the slight progressive rate in order to absorb the hit from the tire and then as more force is applied to the tire, they settle in to keep the tire stuck to the racing surface. We have about 40 sets out in the field at this point and the feedback has been very positive,” says Zimmerman.

The springs can be purchased directly from Team Z’s website and have a retail price of only $159 – pocket change when it comes to getting your Mustang down the track efficiently. For you ’94-’04 owners, don’t fret, as springs for your application are currently in development.
