C5 Brake Upgrade
I have the stoptech brake set up (rotors and pads). I personally don’t like it, it squeaks and I feel like it doesn’t have good stopping power. Do y’all have any recommendations? What are y’all running?

Just street use? Have you bleed the brakes?

There are two points to address.
> squeaks
Yeah, squeaks are pretty common on any higher-performance pad. If you have properly lubed up your slide pins and so forth with high-temp brake grease, consider adding anti-squeal shims or anti-squeal tacky stuff on the backing plate.
> good stopping power
For a street car, every single rotor and street / streetable pad out there will have adequate stopping power. Those cheap $170 amazon kits? They work fine. A full big brake kit from AP racing that costs something like $9000? On the street, it should have virtually identical stopping power, if you use a streetable pad.
So what are we missing here? Are you doing repeated hard stops / holding your brake all the way down a mountain? Are you talking about track use? Or are you talking about a single stop being poor?
If a single stop is poor, either your tires have no traction, your brake pad material is a track-only pad, or you've got a serious issue in your hardware -- air in the brake fluid, stuck caliper, crimped brake line, etc.

To tag onto this, I'm curious how the OP would describe his brake pedal feel. That'd help us deduce a pad material mismatch versus a brake hardware/fluid issue. Be easier to point him in the right direction.

Any issues with uneven heating of the rotors on track due to the vanes being identical and thus wrong on one side? Any issues with padlets wearing too quickly on the track? Caliper flex? Sticking?
