Brakes... Looking for some input. So I am In the market for an brake kit (front and rears)
Baer, Stoptech, Willwood are not options because they only offer brake kits for the front.
I had done research on doing a cts-v 6 piston brembo brake conversion going as far as buying the brackets to do it. But after inspecting someone's conversion I foung that by using the suggested camaro ss rotors upfront you get uneven pad and rotor wear and some pad noise when driving. I dont feel comfortable with rigging the brakes to work like that.
I went on the JHP website to see what they had but all their options are rediculously expensive. 9300$ for the AP brake kit, 6000+ for the old oem Z06 PBR brakes.
I came across
Harrops kits for the VT-VZ holden models the on that really caught my eyes. I definitely want their ultimate brake kit but fitment is the issue requiring a minimum of 19" wheels to have them fit.
Does anybody have any experience with the PBRs? I might settle for those but I have been talking to Forgeline Wheels
about the possibilty of using one of their 18" wheels to fit the Harrop Ultimate Brakes.

What do you use the vehicle for?
The 05/06 brakes are much more capable than people give them credit in most situations. A rotor/pad/fluid/line upgrade can go a long way.

The car is primarily used for street i have used dba 2 piece rotors and hawk performance pads, stock lines. They worked well on the track but I want more braking capabilty and less brake fade.
Can the APs really be had brand new for 6k here in the states? I would only buy them new tho...
Its between the APs and the Harrop Ultimate Brake kit now

I've spoken to folks with both the Harrop kit and the AP. The reason I have the AP is that it has a better feel from what I gathered. The issue with AP kit is the front rotor isn't floating. That can cause dtv issues with very heavy use. There is also the issue of harmonics being transferred into the cabin if not using the right pad compound. Stillen is the main importer of these parts and are hungry for your money. I'd work them for a while, you can get a better deal if you do. They are quick to sell but support is limited should you need it. The kit is the same parts as the oem version, the brake lines were made in house iirc, everything else is oem, except caliper faces have AP on them rather than HSV.

But the thing with Harrop is those MASSIVE 383MM ROTORS
and they fit in most 18" forgeline wheels. Do the math; same pad compound, same rotor properties. The stopping power of the Harrops is just far greater than what the APs could perform.
The larger the wheel diameter the harder it is for brakes to stop the car, among things. So fitting those which are intended for 19+ wheels should have the stoping power unlike anything else.
With my suspension set up/tire selection and the harrops i should definitely stop in less than 105 feet

I would gather that the AP brakes feel a little better on the street. Obviously Holden's HSV division used them for street cars so the reliability is a sure thing.

Been down your road before... the refinement and oem quality of the AP won in my book. I work with Harrop often and can import a kit for you should you decide on it. The only notable issue on the AP kit is the non-floating rotor imo. Anytime you go over 14" in rotor size, floating becomes very important from what I've seen, especially, if you have a rigidity issue on the axle in question. If I don't do the Alcon kit, I'll design a full floating asembly and improve where the oem decided to abandon the further engineering necessary. You might ask stillen if they are willing to make you a floater set for the front. They have the know how if you pay the cash. Although their homemade stuff isn't as good as AP made stuff from what I've seen.

I meant the floating caliper issue with the AP kit. I don't really understand what you mean by it being a problem (fixed caliper vs floating on a larger than 14" rotor).
i still haven't found anyone who can give me their review of the Harrop Ultimate Brake Kit. I am still tied between the two.
I can reuse my current wheels with the AP kit but with the Harrop kit I am looking at a custom 3 piece 18 inch wheel built for them to fit. Its gonna be expensive 10k$ probably a bit more.

I got brake comparisons from both US and AU sources.

By comparisons you mean reviews comparing and contrasting both? Could we all see them?

If you want the best engineered kit available get the Alcon kit if money isn't an issue. They have a 15" rotor option iirc.
You want the next best, get the AP, but consider getting a custom floating hat made.
The rest are not something I'd consider, I believe in a matching rear set.

There was one or two posted on-line. I spoke to several folks down under who had actual experience with the different kits.

I am searching for info right now.

You can also do the CTS-V brakes: http://www.ls1gto.com/forums/showthread.php?t=619778
