Over the last decade, perhaps no company has been more at the forefront of Mustang suspension development than Team Z Motorsports. Team Z’s proprietor, Dave Zimmermann, has spent countless hours testing with his customers at the racetrack. The information gleaned from those test sessions, combined with feedback from the people who are using his products, has been helpful in crafting their newest line of suspension products. The freshly-released ’79-’04 Mustang “Street Beast” suspension system has been in the research and development stages for the last two years, as after examining the market Zimmermann felt that there was a need for high-quality, race-inspired, street-oriented parts.
The 1979-2004 Mustang used the same basic floorpan and suspension arrangement, allowing Team Z to easily create suspension parts to fit all model years within that range. There is only one part number (TZM-SB1) and you just need to let them know what model year your car is when ordering - there are small variances within the design to fit 1979-93 Mustangs, ’94-’95 Mustangs, and ’96-’04 Mustangs. The upper arms are 100% chrome-moly construction, TIG-welded, and double-adjustable with a urethane front bushing.
The lower arms have the same construction but are urethane-bushed at both ends for ride compliance, while retaining the performance that Team Z’s parts are known for. “These cars are 30 and 40 years old in some cases and the torque boxes are almost guaranteed to be out of whack in some dimension. By providing double-adjustment it allows the end-user to get his pinion angle correct no matter what kind of shape the car is in,” says Zimmermann. The kit will be available in two forms – the uppers and lowers combined for $389, and the same kit with a tailpipe-clearing real anti-roll bar for $639.
One of the unique things about these arms is the proprietary bushing material specified for use by Team Z. “We really did our homework on these. I’ve had people asking me for the last two years, bugging me to do a street suspension, and I decided that I wasn’t going to do it unless I did it right. When we started researching the bushing materials that were available, we found that many of the ones that are on the market tear up after a little while – the newer Mustangs were pulling the sleeve right through the bushings,” Zimmermann explained.
Continuing, Zimmermann stated, “We’ve got a proprietary bushing composition that came about after lots of research and it’s performing very well on our test vehicles so far. We’ve got a customer out in California that has been testing them for us on a pair of cars – one is his own 10-second Mustang and the other is his father’s weekend toy. He told us that the new bushings perform so well on the highway that his dad has actually started driving the car almost every day, it rides so nice. And on the performance side, he’s tested the arms in his own car and actually went .04 quicker to the 60′ that he did with our race parts – 1.40 to 1.44. The bushings give a little bit and that actually helps with traction on the starting line.” Check ‘em out!
