Eibach's Pro-Kit Springs - Closing The Gap
Adding Eibach's Pro-Kit Springs Subtracts Unnecessary Ride Height From The Stilted '05-And Improves The Handling, Too
If you're looking for even more drop, Eibach's Sportline springs will be available by the time you read this. The '05 may be all-new, but its design incorporates a number of traditional Mustang cues, including the jacked-up 4x4 look. HiTech chose Eibach's Pro-Kit springs because they improve handling while providing a moderate drop for a much better stance, without making the car too low to drive and enjoy. The dual-rate progressive design is what gives the Eibach Pro-Kit springs the best combination of ride quality and handling, with just the right amount of drop.
One thing everyone (even non-Mustang enthusiasts) can agree on is the fact the '05 Mustang has a distinctive look. Many people love it, some hate it, but most have a strong opinion one way or the other. The '05 may be all-new, but its design incorporates a number of traditional Mustang cues, including the jacked-up 4x4 look.
Lowering springs have long been at the top of the early mod list for most Mustang enthusiasts. Even for owners who don't modify their Mustangs for looks, the stance still has to be right. And if you're going through the trouble of lowering your Mustang, you might as well use some springs that improve the handling performance too, not just slam it to the pavement.
The lowering springs we'll be using for HiTech Motorsport's '05 GT come from Eibach Springs, one of the most well-respected names in suspension performance. HiTech chose Eibach's Pro-Kit because it provides a moderate drop for a much better stance, without making the car too low to drive and enjoy, and improves handling.
We called the guys at Eibach to get the skinny on the Pro-Kit springs. They explained that the front and rear Pro-Kit springs are dual-rate progressive, as opposed to being linear like the stock springs. The hardtop '05 GT's factory front springs are 136 lbs/in, while the Pro-Kit fronts have a 171-lbs/in initial rate and a 229 final rate. In the rear, the stock springs have a 142-lbs/in rate, compared with the Eibach rear's 109-lbs/in initial rate and 200-lbs/in final rate.
