Nearly every car manufactured in the modern era carries a dark secret – fully-adjustable suspension has been all but eliminated in the name of cost-cutting and assembly-line efficiency. What this means for you is increased tire wear and more frequent replacement, as a “full alignment” consists only of rudimentary toe-angle adjustment. For over forty years, K-MAC has been hard at work developing a solution to this problem with patented innovations in camber/caster plates and bushing kits, allowing easy adjustment and a true “full four-wheel alignment” to be performed by any competent shop. These bushings make camber adjustments possible for the first time, and improve the ability to complete toe angle adjustments. When used in conjunction with the K-MAC Camber and Toe kit and Rear Adjustable Trailing Arms allows full adjustability of the 5 multi-link rear arms and positive location. Bolt-on installation – insertion/extraction tube included! Easily adjusted on the car with basic hand tools Unique failsafe locking hardware – set & forget! High quality elastomer compound resists binding Hardened & nickel-chrome plated centers for maximum bushing life 2x the load area of stock bushings Spiral grease grooves

Type: Street/Track, Stage 2
Bearing: PTFE-lined pillow-ball with thin polyurethane bushing

The Stage 2 KMAC plates are a mixed street/track camber/caster plate meant to be used in a variety of suspensions. Since there is less bushing than on the Stage 1, more noise and vibration will reach the driver. The adjustment design is similar to the Stage 1 with a floating mount that sets camber and caster simultaneously. This design allows maximum range of adjustment since no other hardware interferes with the adjustments. These plates can work on both coil over and stock-stype suspensions. Bearing inserts and adapters included. The Stage 2 camber plates are shorter than a factory mount so may not be suitable for cars will little suspension travel. These are designed mainly for adding negative camber for improved handling and not for camber correction back to stock settings (see Stage 1 kit). Detailed instructions included.

Note: suspensions vary from manufacturer to manufacturer. Turner Motorsport cannot be responsible for fitment issues caused by non-stock or specialized coil-over suspensions. As with any race-derived component, additonal fabrication may be required.

Location: Front
Type: Track, Stage 3
Bearing: PTFE-lined pillow-ball, no bushing

KMAC Stage 3 camber/caster plates are designed for track or race-only situations where comfort and noise are not the primary concerns. The Stage 3 camber plates use a pillowball bearing, solidly mounted within the camber plate for direct alignment of the strut shaft and no excess play or deflection. Stage 3 are designed to increase negative camber with their patented 'floating' adjustment that changes camber and caster together. This design allows maximum range of adjustment since no other hardware interferes with the adjustments. Fitment is limited to race-only small diameter coil-over springs (not stock-type). Bearing inserts and adapters included. Detailed instructions included.

Note: suspensions vary from manufacturer to manufacturer. Turner Motorsport cannot be responsible for fitment issues caused by non-stock or specialized coil-over suspensions. As with any race-derived component, additonal fabrication may be required.
