umm.. you didnt read the add.... they wont work on anything but '81 and earlier F-body's

wont work on our cars..

Sorry - should have included link directly to them, they have them for 4th gens also as on this chart.....http://www.kore3.com/tech.php#c5appchart

Emailed them to ask for a 4th gen fbody bracket auction and they replied they would if asked - but wondered if anyone has seen, heard of, or already has them

Guess you are talking about those

If anyone has run these please post up...that price is gooooood.

Wow that is a very cheap bob bishop knock-off bracket. I would not trust that. I have the LG brackets and love them. If you want a bolt on kit go for LG. UMI also makes a good bracket.

No way in hell would I run that on my car. First panic stop and the would get ripped apart. For the work that went into the LG/UMI/BB brackets, theyre well worth the cost.

Just out of curiousity here...what's the difference if that little bracket is steel compared to aluminum? Yeah the aluminum is going to be stronger but is it that much of a difference?

The material plays a part in it. The biggest thing stang kliller and I are talking about is the thickness of the bracket. It would be scared to use it. Look at how thick the LG/UMI/BB brackets are, like stang killer said. That is the cheapest know off I have seen.

Funny thing is they look exactly like the Baer brackets.

Is that a good thing or a bad thing?

so what you are saying is that it needs to be thick in order to be effective? i agree to an extent. but thats not a very acurate statement to go by.

it depends on the quality steel grade that is used, in this case its HSLA A572 which is low alloy high strength steel plate, generally used in structural applications.

its mechanical properties are as such:

Mechanical Properties A572 Gr 50:
Tensile: 65 ksi min
Yield: 50 ksi min
Elongation: 16% min in 8” 19% min in 2” (for plates wider than 24”)

so you need to find out what the other companies use for their brackets, before you make an assumption based on 1 small picture.

anyone know what the other companies use?

That design seams to work for Baer

i just spoke with my father in CA. He has been an aerospace engineer for 36 years, mostly deals with aluminum alloy's for aircraft parts. i sent him the mechanical spec's of the steel i listed above.

he said that this steel is plenty strong enough to use. The main factory is going to be the thickness of the plate, and the grade hardware used, which he said anything 1/4" thick or greater of this steel plate would be ideal.

i just emailed LGmotorsports and UMIperformance to get the specs of their aluminum that they are using.

I asked my father about certain common aluminum alloys people use. His response was that T 3 series aluminum would need to be pretty thick to be on par with this particular steel, and that T 3 series aluminum would not be his choice to use for this type of bracket. T 6 series is what would need to be used to be compaired, but he said in some cases, tends to be brittle if not propery forged correctly.

and lastly he also stated that the steel is going to be more heat resistant that the aluminum, (but in the case, this wont apply that much since the parts in question dont have direct effect of heat on the rotor)

i'll post my findings when the companies reply to me.

Thanks KiLLJOY92Z28, thats the kinda response I was hoping for. Look forward to your findings..........

Same here. I'll probably pick up a set when it comes time to do brakes.

Remember, failure is only one of your concerns with this bracket. If the material is not rigid enough, the caliper will "pull", which will twist the bracket and cause tapered pad wear. I know that the Baer kit has been known to taper pads under track conditions (at least in some cases). So, while it's probably not going to "fall off", it may not have the rigidity needed to keep the caliper square with the rotor during use. The force on these brackets is not just a vertical load.

I ordered a set and will post when I receive and install them.

Got a reply from Tobin:

I am always willing to discuss KORE3 products with anyone who is interested. We believe in our products and put them against the competition without hesitation. If people believe that they need to spend $200+ for a set of brackets for them to be safe then that is their choice.

KORE3 created the 4th gen F-body C5 kit at the request of F-body owners tired of paying a premium for performance products. Others have expressed concerns with the fatigue, corrosion, rigidity, and other material properties associated with using high-strength aluminum alloys in this application. We've looked at using 2024, 6061, and 7075 heat-treated alloys and chose to use steel because it outperforms and outlasts aluminum in virtually every way, and it does so with higher factors of safety.

E-mail him back and ask him if he's lab tested them and how much load they will take before failure.

I was looking for that thread that Bob Bishop posted that had all the tech info about the test that he did and so forth so on, but the search kept taking a dump on me, its a ton of good info in that one.
