One of the holes for the bolts needs to be 1mm larger, it is no big deal to make the hole bigger.
I do not think there is any weight difference, if there is it is neglable.

Subman,

Now that the rear links are on, due you notice the car reacting quicker to your inputs?

If you make a quick lane change does the car perform better?

I'd suggest that the car would handle better with 1-3 degrees negative camber. Using adjustable links to return to stock camber saves tire wear.

To be honest with you there has been no noticable handeling difference in the car at all.
Negative camber does make a big difference in handeling but, the place where you can tell is in the front wheels and not the rear. The only reason I got the camber links was to increase my tire life. I like the way the negative camber looks but it is not worth me trashing my tires.
