These paltes replace your strut tops allowing ~ 1.5 additional degrees of positive caster and ~ 1.0 additional degrees of camber (over what you are able to obtain w/ the oe eccentric bolts).
First you need to remove the struts- you need to unbolt the two bottom strut bolts (19mm), before you do mark the top one- this is the eccentric bolt. On the bolt side there are hash marks on the bolt and an alignment mark on the strut- scribe the bolt to get you back to where you were (even though you will be getting an alignment). There are the brake line and speed sensor which also needs removed form the strut- 12mm. On top there are three 12 mm nuts holding the strut to the firewall- remove these. Gently remove the strut.
