hope you had the car aligned after fitting as the one of the pinch bolt hole is elongated to allow correct setting when lowering and adjusting the camber. there is no way without a proper alignment machine to get this right and will be why your tyres are scrubbing. i had the rear squeaking it is where the allen adjuster comes through the strut top, you need to make sure it is not touching metal when bolting in.
my tip is some tape round the allen bolt to keep it centralized in the hole.
