Yeah,

I have some of the brackets. We bought some to get a idea what it takes to make them. Basically I wanted an idea of where to mount the caliper and the rest is competely redesigned. The bolts don't even fit in the holes with out interference, don't know how you get the proper TQ on the bolts when there is that much hangup. So therefore my redesign.

Looks like I will make 5 sets of brackets to start and they look to be all spoken for. I will make more if the demand warrants it. They will be made out of 6061 Aluminum and that's as strong as the steel that the orginals are made of, plus it will be about 1/3 the weight. Cutting the unsprung weight that much on this upgrade is a pretty good deal. Plus you get much better brakes.

I'm also going to talk with a dealer about getting the parts at cost so I can offer a whole kit. The brakets should go for about $250, just like the previous ones and fit LS1 and LT1 cars.

If you have any questions on them e-mail me.

$250 for just brackets or the whole kit?

Z~

 

whoa! i was told by bob in an email that because the brackets were to be made to this aluminum that they would be half the cost, and would only be $115 for the front brackets.

 

Yep its 250 for just the brackets.

 

I don’t know know how much slop you plan to leave around your bolts, but I spent 2 months looking for a machine shop that could fabricate my brackets to the tolerances needed. If you have bolt holes larger than the diameter of the bolts, then the bracket will skew when the customer tightens the attaching bolts. This allows the brake pad to skew across the face of the rotor and widens its path, applying more heat to the outside edge of the rotor, which facilitates rotor cracking. That is why Chevrolet located the caliper precisely, and so do I. Machining to that precision costs a lot more money, but it is necessary for correct alignment. When you demand that the holes be within .001” of the diameter of the bolts, then it also becomes critical that the center-to-center distance of the holes be perfect. I personally fastened each of my adaptor brackets to a C5 pad abutment bracket, so I know that each one is exactly right. With over 60 customers, no one has ever complained about the fit of the adaptors. Well, except for now, when someone hopes to make a lower quality nock-off and sell it for more money.

You don’t say which 6061 aluminum alloy you plan to use, but if it is the normal T6, then the low carbon cold rolled steel I used in by brackets is 307% stronger in shear strength (3,770 ksi vs. 11,600 ksi), and over 35% stronger in tensile strength (44,950 psi vs. 60,900 psi). How can you HONESTLY say that it is as strong as my bracket?

Anyway, I am now finishing the design of a new front side adaptor which will replace my older adaptors, no longer in production. My new adaptor brackets will attach to the factory caliper mounting bosses, and be about 1/3 the weight of my previous design which you are trying to copy. They will also be cut from one piece of 304 stainless steel. That material is about 20% stronger in tensile strength than the carbon steel I used to use, and stronger in shear strength also. And MUCH stronger than any 6061 aluminum.

My new brackets will sell for less than $120 per set, including the correct strength mounting hardware, and full instructions.

Maybe you would like to buy a set and copy them.

Bob Bishop

 

you go bob!! let me know when you have my brackets ready!

 

 

Bob, i'm interested in your new design. i'' e-mail you and keep in touch, i would prefer a "original" versus a copy.

 

Bob,

Well since we have CNC lathes, that can hold a tolerance within .000005 I figure we can machine the parts pretty easy. That and have the CNC mill make the plates. I wouldn't say that's a lower quality knock off. I thought a steel, flame cut version was pretty low quality. We make CNC parts everyday, from parts that go into Top Fuel Dragster Blowers, to pins in your airgun in your garage, and parts in the copier/printer on your desk.

What I found with yours is that the holes are not reemed out. Once you weld them all that trouble of making the holes the right size is worthless unless you redo them to fix them. It's not that the hole was the wrong size it was just manufactured wrong. Going with the stock C5 spindle hole size or with a little better tolerance will be a better deal. IMHO

Your right I never said what grade 6061 I plan on using. The Al is going to cost more than the steel but at 1/3 the weight it's a better deal. On top of that why do you need all that heft with the old design? The C5 spindle is made of 6061 and holds all of the braking loads a C5 can throw at it even with race tires. Never seen a C5 spindle sheer apart..... I know people over engineer aftermarket parts, my engineer does that too, but by god it's excessive in my book.

The part that got me was I was told that your bolts were $40!!! I found the same grade ones at a total price of $8. Don't know if that was all B.S. but having good suppliers for parts is a big deal.

Your first design was bascially a copy of the Baer GT bracket. You just reengineered it too, if you didn't that's alot of wasted R&D time to me. Unless you want to patent these things, people with the means will copy them. That's the risk you take.

Interesting on the new design. We could make that too. Seems that you would need 2 different ones for the LS1 and LT1, but maybe not. I'll check the spindles I have in the shop and see what I can do. Good idea. Not going to need to copy yours, we could just change our design right now and work on the new one. I'll get the engineer to start looking at that.

Might be a better idea to just make the front C5 arms and spindles fit in there, just like we did on a early A-Body GM car...... It would solve the crappy camber curve we get with this nice 4th gen suspension.

Nevermind that's a joke.

Not trying to rip you off, but since we have the tools to do it, it's just one less person that has to mark them up before the customers buy them. I'll see what price mine come in at.

Chris 96,
I can't get your link to work

SSstroker,

are you going to be selling a complete kit or jus the brackets?

Thanks

 

My site is hosted on a hosting account I use for my car club. Last night hackers got in and posted anti-american, anti-war crap on the club website. The hosting company is repairing the damage and has taken the entire account offline, so the nashvillespeed.com web will be down for a while too.

Keep checking it though...

 

I have Bob's brackets and can tell you that they are first rate quality.

I don't see where improvement could have been made and I commend Bob on being innovative enough to produce these brackets.

 

Here's what the Baer Brackets look like

Now if you've seen Bob's Brackets, then you'll realize that his are a direct Knock Off of these. So who's copying who here? The Baer GT Packages use C5 PBR cailpers from Austrailia. BTW I think LG even offers a kit based of this too.

We will sell the whole kit. I will sell the GM too if need be, and I am going to work with Earls or another company to get stainless lines, and maybe retail, EBC pads, and Eradispeed Rotors to go with the kit. I'll also do a spindle trade if needed, I'll cut the spindles and then powdercoat them for you so it's just a bolt on kit rather than having the customer cut the spindle themselves.

Once you drop a set of these brackets into the hands of a few good machinests and engieers they jump all over how to make these things better. Making parts better is why we have the SBC and LT1 engines we have today, if nobody made them better we would not like a 165hp 265 cube engine.

Bret

 

Bob,
I look forward to hearing from you in the next week or two.

 

No need to jump all over Bret here, hes just trying to make your product better....which obviously offended you Bob. I have been down to Brets shop many a time and if your hung up with a tolerance of .001" your outta your league. Seriously though his equipment can far out do that in both design and quailty in my opinion. Also like Bret mentioned $40 bucks for bolts because they came from Italy. come on now.

Take a step back, no need to jump on his case.
