need help quick (stoptech brakes)
trying to change the street pad back into the caliper, I couldn't put the pads back in because the piston is in the way, what kind of tools/method should i use to push the piston back in?

use your fingers and thumbs
you might have to press/squeeze a few times. Take the cap off the brake reservoir and monitor that it doesn't spill over while you are squeezing.

Re: need help quick (stoptech brakes)
you could go ghetto sty-o and carefully use a long flathead screwdriver (what i did at the track b/c i forgot my piston retractor) and wedge it so that you have leverage against the piston, or to do it properly use a proper piston tool like this:

you can find it at a kragen/pep boys type stores and should cost less that $10. it should be called brake piston tool or something along those lines. you don't want to use the cube-type piston tool since those are designed for parking-brake activated brakes (eg. our rear brakes)
make sure to loosen the brake fluid reservoir cap so that the fluid can go back into the reservoir when you retract the piston (and make sure you retighten it when you're done!)

I just use the blunt end of my socket wrench.
If you have a big difference in the thickness of the pads (i.e. track pads are thin and street pads have lots left), you may need to unscrew the cap on your brake fluid reservoir in order to push the piston back enough to get the thicker pad back in.
I typically just leverage the wrench against the edge rotor and gently squeeze the piston back in. You may need to repeat this for both pistons and on both sides of the caliper. It sometimes helps to get a second tool to get the two pistons on each side at the same time. Be gentle and as long as you don't get violent with this technique, you will not harm the rotor.
If the difference between your street pads and track pads is huge, you may need to bleed off some of the bleed fluid that flushes back up into the reservoir.
