These little screws always rust and bind and cause troubles getting your rear rotors off so, chances are you'll be needing some new ones after you totally destroyed the ones that are on your car! These are actually a little better than the originals because they incorporate a Phillips head which has more engagement than the standard flat head. Get them here now with your caliper, rotor and pad order and "Save 1/2 Off Department Store Pricing!!" (Geeez... I need a life. I've been watching too much TV).
Tip: Here's a couple things to consider when dealing with these fun little screws. #1. Use an impact driver and TONS of heat to get the old screws off. A MAPP torch is an invaluable tool here. Impact "driver" not impact wrench. #2. Use an anti-sieze compound when you put these in so the next time will be a breeze.
