K-Mac

This increased range and precise adjustment capability means at last ongoing issues of steering pull to one side, straight line high speed directional control, excess inner edge tire wear or being able to reduce lap times by increasing front negative Camber on race days can now all be resolved.

Fitting of these front and rear kits requires no special tools and allows future ongoing adjustments when altering height, fitting wide profile tires or simply to re-adjust for curb knock damage.

The adjustable front caster bushes also reduce dive, lift under brake and acceleration, along with improved steering response and traction under braking. They feature a unique K-MAC 2 axis/all positional bush design. This allows suspension arms to travel through their required arcs without binding. Also having twice the load bearing area of OEM rubber bushings that use air voids which can cause vibration, wheel hop with loss of traction under braking and subsequent premature bush failure.

An added bonus with the K-MAC adjuster kits is an entire bush upgrade as these 4 bushings for the front and the 4 for the rear are the vehicles main high wearing suspension bushings.

Example of K-MAC bushing strength/quality is the near identical bushings being used in the current Australian and New Zealand V8 race category where the G8 versus Ford. This all out competition racing – main straight top speed, then hitting race curbs, slamming down after becoming airborne! After 18 months of evaluation race scrutineers ruled the evidence had shown that for the safety aspect and reliability no other front end Camber and Caster adjuster kits other than K-MAC would be allowed to be used. The opposing Ford drivers were also instructed likewise.
