New front brake setup, what do ya think? I'm getting ready to replace my front rotors and pads, here's what I'm thinking I'd like to do. I'd appreciate any feedback.
F-body Hawk HPS front pads
C5 conversion brackets
C5 Powerslot rotors
If anyone has ran a similar setup, I'd like to hear the results.

It won't work. You need to buy the Corvette PAB (Pad Abutment Bracket, the bracket that holds the pads) for that kit, the Corvette calipers and you'll need Corvette pads (to fit the Corvette PAB). And, I'd buy standard "blank" rotors, unless you really want the look. Slotted rotors are not really an upgrade and not at all "useful" on a street car (other than to make vibrating noises when you stop and grind your brake pads into dust faster than normal).
You can't use the F-body parts with the UMI kit. Sorry.....

You caught me before the edit, lol. I was misinformed about one of the bracket types out there. I was under the impression one of them moved the F-body caliper out, but that's false.
I think it'll be:
Hawk HPS fronts
Powerslots or Brembo blanks (any good vendor for the Brembo blanks or another good blank type? Most seem to be slotted or drilled)
I hadn't heard that about the vibrations, I knew they chew up pads faster. That definitely is more points against.

I bought a brake kit with slotted rotors, and under hard braking, I'd get a "whirrrrrrrr" noise from the slots. It wasn't super annoying, but they were also destroying pads (autocrossing) and I'm not a fan of them anyway (and that set reminded me why) so they didn't stay long.
Strano and tirerack (and possibly others) carry the Brembo OEM rotors and those pads. I'd stick to the blanks.

It will work, its the LG C5 Relocation Brackets, they just move the caliper out more thus allowing you to run a larger rotor. Thats what I plan on doing in the near future.
Of course which rotors you go with is up to you, I know you autox'd the car so if you plan on doing it some more I'd go with the blanks otherwise, slotted/drilled for pretty.
Hows it going by the way?

I have relocation brackets, rotors, pads, PAB, guide pins ... everything but C5 calipers I would sell pretty cheap.
Everything is new GM (except for the relocation brackets), in the box, never installed. Sold the car they were going on.
PM me if interested.

Would you please point out where I could look for this? I don't see anything like that as it sits now. LG also assured this setup works great.

Trackbird,
Ok I will check for this tonight. As I have to un-screw up my genius placement of the ware indicator pads (put both on one side
)
I'll take pictures for you to show you what I'm seeing.

Notice how the PAB gets really close to the beveled edge of the rotor hat? If you have clearance, that's great. But I've seen some rotors that have a square hat and not so much of a bevel. Something to consider.
Also, because an F-Car rotor is 1" smaller in diameter, the pad is arced more than a C5 pad. The back side of the F-Car pad (the edge furthest away from the center) overhangs the rotor ever so slightly.
Ever feel a worn rotor and it has a thin "lip" on the outer edge? On these, you will see the edge or lip develop on the pad.
The only issue I ever had with the pad was a little knock back when the pad was worn 50% or more.
Just keep an eye on it.

Awesome information guys. So essentially, I should be fine but should keep an eye on it is what I'm gathering. I'll take some images of what I see tonight. After setting everything up there was 0 interface between the rotor/caliper and everything spins freely. When I fix my wear indicator orientation tonight I'll double check. I think I'm ok though.

Maybe my brackets are just made a little better then some from before?
Anyways, doesn't seem like an issue at all but I'll keep an eye on it.

jeffstar, that is exactly the overhang I am referring to.

Well, it's miniscule but I will keep an eye on it and I will dig this thread up or create a new one if it becomes a problem. In fact, what exactly would the problem be that it would create?
