Designed : to fit with OEM diameter at top of coil springs. Also see # 201816- L for Coil-Overs (60- 70 mm ID).
GENUINE K-MAC – WITH THESE REPLACEMENT TOP STRUT MOUNTS WE HAVE ADDED EVEN MORE FEATURES :
K-MAC invented and is the only manufacturer to provide “precisely” adjustable Camber and Caster top mounts for these models – no modifications to fit and can be adjusted accurately from engine bay.
Up to “22mm” (7/8″) of Negative (or Positive) Camber. This equates to ‘1.5’ degrees (+ or – depending on vehicle height. Also see # 201816- 1G ( Commodore VE- VF), these are K-MAC LOWER ARM CAMBER ADJUSTABLE BUSHES up to extra 1 degree (plus another one degree available OEM). MAKING TOTAL OF 3.5 DEGREE NEG.
This means (in the pursuit of pole setting lap times) on “track days” – dramatic reduction in understeer to hit those “corner apexes” every time and allow to go deeper into the corners with improved traction and braking response.
Other K-MAC adjustable strut top design features include the short life plastic encased OEM bearings are replaced with a unique system – extra H/Duty 40mm diameter self align spherical bearings (PTFE lined), then “separate” H/Duty (massive 85mm diameter) full sealed radial thrust bearings for steering loads – also preventing spring drag/binding. Bearings are replaceable for virtual lifetime usage and no height increase. FIT WITH ALL BRANDS OF COIL OVERS – 60 TO 70MM ID AND MINIMAL STACK HEIGHT.
Can also use in conjunction with K-MAC front lower arm “bushing kits” – precisely adjustable Caster (thrust arm) bushings that also improve brake and steering response (and for VE, VF, G8 models precisely adjustable lower arm Camber bushings that also can adjust to increase track width!).
* ALSO SEE COMPLETE RANGE OF THESE “FRONT AND REAR PRECISELY ADJUSTABLE CAMBER, CASTER, TOE BUSHINGS ” All the very latest KMAC 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 KMAC patented design – single wrench on car, allowing accurate adjustment “under load” direct on alignment rack). With the “Camber” bushings providing also “extra” track width (and negative adjustment) on race days.
