What causes inner edge tyre wear?

Inner wear is primarily caused by excessive negative camber, which is often exacerbated when a vehicle is lowered without proper geometry correction.

Do I need to modify my chassis to install these kits?

ABSOLUTELY NOT. K-MAC ALIGN engineers every kit as a direct, BOLT-ON replacement for your OEM parts. NO MODS!

Will adjustable components fix the steering pull?

YES! True independent Caster adjustment eliminates directional pull and drastically reduces front-end dive under heavy braking.

Why are your kits better than factory components?

Our uprated materials resist the flexing and tearing common in standard rubber, ensuring your alignment settings remain locked in during aggressive track days or daily commuting.

Are specialist tools required for ongoing adjustments?

NO! Our patented systems allow fast, precise on-car adjustments using standard workshop tools, saving you valuable time on the alignment rack.

NOTE: Superceded by #501926K kit. Easier to install and also to “precisely adjust”. While upper arm kit (#501526-1M) NOW ONLY RECOMMEND IF WANTING “EXCESS” - NEGATIVE CAMBER. Example fitment of extra wide tires (mounting top of tire “inwards” to clear outer fender). New kit #501926K “replaces and uprates” original lower arm bushes. Also allowing fitment without control arm removal. Along with easy access, precise single wrench adjustment (direct on alignment rack UNDER LOAD). Unlike upper arms - Does not reduce important clearance top of tire to outer fender - when wanting to resolve excess inner edge tire wear !
