It's time to replace the brakes and rotors on the newtome V50 T5 AWD with 320mm brakes so I ordered the Powerstop drilled and slotted Z23 kit. Successfully did this in the past with 300mm discs on my S40, and I was impressed with the stopping power. So I didn't think anything of ordering this kit. Imagine my surprise when I see this - this is what I got for the front pads (back side shown). Not only does it not come with anti-rattle clips at the top but it has this attached tri-spring on the backside. Am I missing something - does this 'spring' fit inside the caliper and straddle the piston? I just cannot imagine it fitting any other way. Never seen anything like this before... Thoughts???
