I'm not familiar with your coilovers, and if they come with a slot/factory adjustment, but assuming they're the same as the factory McPherson mounting setup (yours has 3 bolts instead of 2?) you can either slot, install crash bolts (bolts with an undersized shank), or install one eccentric bolt. Slotting works great but will be a bit annoying the adjust. Crash bolts are easy and are typically an OE-approved way for correcting camber, but don't give you a lot of adjustment. The eccentric bolts are the best option for ease of adjustment and give you a pretty wide range of adjustment, but are widely debated in terms of how safe they are since you are reducing the bolt shank diameter. Eccentric bolts are my personal choice... I have a daily with 10 years on eccentric bolts, and a race car with 4 years on eccentric bolts, and no issues, but I know a lot of people aren't comfortable with them.
