K-MAC – Always 1st. with the latest design breakthroughs (the experience of manufacturing adjuster kits longer than any other company), it shows with all the latest Race Winning upgrades:
PRODUCT: Manufactured not from steel or soft billet alloy but the highest 7075 aircraft grade aluminum. Extra H/Duty self align spherical bearings (self lubed – PTFE lined). No Elastomer/Flex for tauter/quicker response times and more effective shock control (centers are also “replaceable” for virtual lifetime usage). With K-MAC – Separate top spring seats are included with H/Duty radial thrust bearings for “Steering Loads” (which also resolve annoying spring drag/binding)…. for both OEM diam. springs and all 60-70mm I.D. Coil Overs.
FEATURES: Simply replace the existing front top strut mounts (no modifications). Reinforcing the strut towers and with the unique K-MAC patented design providing the biggest (and quickest) adjustment range of both Camber and Caster. Street/Race settings can be recorded and changed in 30 seconds – just the time taken to loosen the 3 top mount nuts. Another K-MAC Patented design feature allows this fast adjustment to be made accurately under load. Also when adjustable “coil overs” fitted the K-MAC design provides minimum stack height for maximum vehicle lowering and shock travel/absorption.
ON TRACK DAYS: Ability to hit those corner apexes every time by being able to dial in extra negative Camber to reduce understeer/increase traction and allowing to go deeper into the corners with again increased traction and also braking response. In the pursuit of lowering lap times and “Front row of the grid” on race days!
RESULT: Finally – The adjustment capability to resolve costly premature edge tire wear and steering pull, a result of altering height, fitting wide profile tires/wheels, load carrying or curb knock damage. Along with ability to improve traction, understeer/oversteer.
*ALSO SEE COMPLETE RANGE OF “FRONT AND REAR BUSHINGS” All the very latest K-MAC design breakthroughs to resolve premature bush wear. Most bushings feature twice the load bearing area of OEM and are 2 axis / self aligning – without the use of air voids. Result is improved brake and steering response. The Camber, Caster and Toe bushings are also precisely adjustable (unique K-MAC patented design – single wrench on car – accurately under load direct on alignment rack). With the “Camber” bushings providing also “extra” track width (and negative adjustment) on race days.
Porsche 981, 986, 987, 991 Front Camber & Caster kit Stage 3- (Full Race) 580616-3LWhen 2nd Best 1st Enough ….ALL THE LATEST DESIGN BREAKTHROUGHS NOT FOUND IN OTHER BRANDS ….( Incl. Very Latest 2019 Updates )WHAT YOU WOULD EXPECT – THE EXPERIENCE OF BEING THE LONGEST ESTABLISHED ADJUSTABLE STRUT PLATE AND BUSHING KIT MANUFACTURERS AND WITH PROUDLY “IN HOUSE” MANUFACTURE – NOT SOURCING IMPORTS/ RELABELING. ALLOWING TOTAL CONTROL OVER QUALITY AND WITH IT RAPID, CONSTANT DESIGN IMPROVEMENTS (Do appreciate any constructive ideas you can suggest how we can further increase our market leadership).
Genuine K-MAC NOT MANUFACTURED FROM STEEL OR SOFT BILLET ALLOY: But the very highest 7075 aircraft grade aluminum with “Extra H/Duty” self align spherical bearings (self lubed – PTFE lined) then encased in elastomer to extend life / day to day commuting (centers are also “replaceable” for virtual lifetime usage) and designed for minimum stack height.
ANOTHER K-MAC UPDATE INCORPORATED INTO THE DESIGN: Separate radial thrust bearings to take the “Steering Loads” (which also resolves annoying spring drag/ noise/ binding). Massive 85mm (3 3/8″) diameter fully sealed bearings (again by far biggest in the industry) and also included are OEM diameter alloy top spring seats along with separate seats to suit all brands of coil overs 60-70mm I.D.
FEATURES / ADJUSTMENT RANGE: Replaces the existing Strut Top Mounts (no modifications). Reinforcing the strut towers and with the unique K-MAC patented design providing the biggest (and quickest) adjustment range of both Camber and Caster. Street/Race settings can be recorded and changed in 30 seconds – just the time taken to loosen the 3 top mount nuts. Another K-MAC Patented design feature allows this fast adjustment to be made accurately (under load) direct on alignment rack.
NOTE : SUPERSEDES THE CURRENT INDUSTRY STANDARD WHICH HAS BEEN AROUND FOR YEARS – ‘SLOT’ adjustment. Unlike K-MAC are only available in a solid / uncompromising STAGE 3 Full Race version (steel sphercial bearings mounted on a non shock absorbing steel plate).
THIS SLOT DESIGN, BESIDES PROVIDING LESS ADJUSTMENT because of the need for access to the hold down bolts, is also time-consuming to adjust and on many vehicles requires removal of the strut.
Note : Most brands the “single” spherical ball is also taking the steering loads.
Unlike K-MAC where all Stage 2 (Street/ Race) and Stage 3 (Full Race) incorporate purposely designed vertical thrust bearings ( these are fully sealed and massive 85 mm diameter). Reducing steering effort and preventing annoying noise through spring drag / binding．
ON TRACK DAYS : ABILITY TO DIAL IN “EXTRA NEGATIVE CAMBER” TO SIGNIFICANTLY REDUCE UNDERSTEER, in the pursuit of hitting those corners apexes every time and allowing to go deeper into the corners with increased traction and braking response. With the result of further lowering lap times in the quest for front row of the grid on race days ! (also see below front lower control arm adjusters for extra adjustment.)
RESULT : Finally – The adjustment capability TO CHANGE TIRE “CONTACT ANGLES” to correctly resolve costly premature edge tire wear and steering pull. The result of other than showroom height conditions – day to day commuting, encountering high cambered roads, altered height through load carrying or lowering, fitting wide profile tires/wheels and curb knock damage. Along with the ability to improve traction understeer/oversteer.
*ALSO ● ● ● ● SEE COMPLETE RANGE OF “FRONT AND REAR BUSHINGS ” 1st. ITEM TO FAIL. ALL THE VERY LATEST DESIGN BREAKTHROUGHS (Experience of manufacturing performance bushings longer than anyone else – 1964). Resolving costly, premature bush wear with resultant wheel tramp, vibration, loss of traction under brake and acceleration.
CHECK LIST / EXTRA FEATURES K-MAC BUSHES VERSES OTHER BRANDS: Where other brands merely replace “OEM rubber bushes with urethane “ to eliminate the OEM oil and air voids in the endeavour to improve brake and steering response. The problem here is that with today’s autos multi link arms and different mount angles, this inhibits the suspension arms traveling through their required arcs which can cause even more wheel tramp / loss of traction with arms binding, locking up and lead to breakage!
K-MAC bushings therefore where required are “Mono ball / 2 axis / self aligning ” with the unique design providing more than two and a half times for both the load bearing area and shock absorption over of OEM bushes.
This K-MAC design breakthrough also finally resolving once and for all the issue with “steel spherical bearings“. Their wafer thin teflon style liners used soon pounding out with resultant metal to metal contact, noise.
Also because of ever increasing speed of assembly lines virtually all today’s Autos now only have Front and Rear Toe “directional adjustment”. Most K-MAC bushings therefore are adjustable for Camber and Caster allowing to change tire “contact angles” – essential to resolve costly premature edge tire wear and correctly fix steering pull.
THE ACTUAL K-MAC “PATENTED DESIGN BUSH ADJUSTMENT SYSTEM” HAS REVOLUTIONIZED THE INDUSTRY – PRIOR TO THIS – THE LAST 40 YEARS HAS REQUIRED THE NEED FOR LABOUR INTENSIVE DISASSEMBLY AND BUSH REMOVAL. THEN THE INACCURATE TRIAL AND ERROR NEED FOR BUSH REPOSITIONING EACH TIME TO CHANGE ALIGNMENT SETTINGS. INSTEAD NOW WITH K-MAC WE HAVE CHANGED ALL THAT – IT IS PRECISE SINGLE WRENCH ADJUSTMENT ACCURATELY ON CAR (UNDER LOAD) DIRECT ON ALIGNMENT RACK. THEN SECURED BY THE K-MAC UNIQUE “POSITIVE LOCK” SYSTEM.
