My wife's XC70 needed new tires and at that point I decided to increase the wheel size from 17 to 19 inches so I bought a set of wheels and tires from a big one Load. the company's line that I used before. There were new wheel bosses in the combo package but they weren't quite what I was looking for as each bolt head was stamped with the bolt information and the chrome plating wasn't that good. I chose this McGard install kit because I needed wheel locks and decent looking chrome bolts. In this respect McGard's product is excellent. The bolts and lock are PCD variants (like the standard Volvo bolts) which means the tapered 'washer' floats and allows for around 2mm of movement when the wheels are aligned during installation. I have a complaint with McGard and I removed a star for that. I've been trying to find four bolts that match the bolts in this kit in case something "happens" with the lock bolts. You can buy replacement screws all day long as long as you want a quantity of 50. I don't need 50 screws, I don't want 50 screws! Come on, McGard provides replacement screws in one batch!
