If you are running modern radial tires you should not follow factory alignment specifications for caster, SPC recommends 3° of caster to promote return to center steering. Stock strut rods on the 1st generation Mustangs are non-adjustable and often have worn bushings that can cause unwanted movement of the lower rod assembly and poor handling. A must for early Mustangs, SPC's adjustable caster rod features low durometer OE-style bushings to protect the chassis mount from damage and has easy caster adjustment. It will provide the positive caster needed for improved tracking and modern geometry. If you want to adjust camber as well, look at SPC control arm kit # 94215.

California Residents WARNING

This kit bundles a pair of EZ cams (p/n 81260) for adjusting camber +/-1.5 degrees, with two 72355 Caster Bolts. Together these parts overcome the non-adjustable factory design to provide complete adjustability for improved handling, educed tire wear, and better drivability.

California Residents WARNING

These adjustable strut mounts feature polyurethane bushings for quiet operation and maximum performance, and are CNC machined from 6061 heat treated aluminum.

SPC aluminum panhard bars provide weight savings and adjustability! Manufactured from aircraft grade aluminum, precision TIG welded, and then black anodized, the SPC panhard bar is the lightest durable unit on the market. High durometer vulcanized rubber bushings promote precise handling while maintaining factory noise levels and dampening qualities. SPC's bushings are the same size as factory bushings and lend themselves to other aftermarket bushings if stiffer bushings or different materials are required. Adjust your Mustang SPC panhard bar on the car to optimize lateral stability and tracking. Arm length is 36 inches. Complete your suspension tuning project plus get additional pinion and trust angle adjustments by using SPC's adjustable trailing arms #72345.
