When it comes to their Mustangs' suspensions, most owners choose to lower their cars with a set of aftermarket springs. The new springs improve handling by altering the spring rates from the stock springs and by lowering the vehicle's center of gravity. While springs are effective, however, they are only part of the suspension equation.

Many factors-including K-member design, suspension mounting points, steering linkages, and so on-can determine whether other suspension products are necessary to make the car handle to its fullest potential. Some cars, usually '90 and newer, don't need bumpsteer correction unless the car has been drastically lowered. But one product from which all Mustangs can benefit is a quality set of caster/camber adjustment plates.

Caster/camber plates take the minimal adjustment capabilities of the stock upper strut mounts and make the strut completely and independently adjust-able for both caster and camber adjustments. Many aftermarket caster/camber plates improve the vehicle's handling by replacing the soft rubber strut bushing with a harder durometer urethane bushing, or even solid-steel spherical bushings. With larger-than-stock tires, lowering springs, and so on, a good set of caster/camber plates is exactly what's needed to tie everything together and to allow for a performance alignment.

J&M Products makes a high-quality caster/camber plate for '79-'93 and '94-'04 Mustangs. These super-strong adjustment plates are powdercoated and feature precise TIG welds. The Teflon-lined spherical bearing offers precise handling and increased suspension travel for lowered cars. At $152.50 (including shipping), these caster/camber plates are a great deal.
