yea, they look good to me. the v-spring is just meant to pull the pads away from the rotor after you finish braking, just to provide a little spacing. You will need to recess the pistons before you can really slide them over the rotors. The front pistons can be forced back with a clamp or something of that nature, but the rears you will need to take a pair of needle-nose pliers and twist the piston head clockwise to make it draw back. it can be a real PITA.



Also, make sure that the little spring-wire that retains the pins thru the calipers is in good shape. I had mine break while driving and one of the pins worked its way out... really fucked itself up bad on the rim, and scraped the rim up a bit too. Overall not a good thing.

Ah yes, I ordered all new hardware so those particular springs are brand-spankin' new. Thanks for the heads-up.

Don't use needle nose, go buy the 10 dollar tool to do it right.

Yes, I found it impossible to get the rear pistons back in without the little rubix cube tool.

I got mine the first time to my fingers disapointment.

Yeah Autozone or any parts store should have one.
