So what about the rear calipers now that we are putting on nice big red ones up front?

Alternatively, you may get standard C5 front calipers (same price) which are a dark gray, and don’t call attention to themselves.
Concerning performance, use good brake fluid and keep it fresh, and use rear pads appropriate for your application (street, AX, road race). Under maximum deceleration, the front brakes are doing approx. 80% of the stopping.

As far as the "standard" C5 dark grey calipers, are they any different in performance or safety or is it just asthetics? I personally do not want to have bright red calipers sticking out from under my wheels, especialy ones that have the word, "CORVETTE" emblazoned on raised lettering. I am, however, willing to go that route if the standard C5 calipers are less in quality/performance/safety then the red CORVETTE ones.
Do you know if the standard C5 calipers are the same? If so, does anyone have the part number for them? Bright red calipers on my Navy Blue TA w/Black wheels just doesn't sound like it would look too hot.
TIA,
Respectfully submitted,
Darrin

There is no difference between the 2 calipers but the color. There is a link to the parts list on the 2nd post in this thread. It includes the part #’s for both caliper colors.

Also,
It seems pretty clear that these are the best quality option at present, and if that is the case then thats what I want. However, and I certainly dont want to rain on anyone's parade, but if Bob is truly out no one should mind me asking... where can I find this other mystery manufacturer? I have been looking for quite some time to find these brackets from Bob, now I find he is no longer making them, and I have yet to find another source. Anyone mind posting a link? I am definitely willing to wait until June to see if Bob will make some more (PLEEEEEESE put me on the list), but I really want to upgrade to C5 calipers and we need a backup plan!

For those that are looking for a C5 brake caliper bracket, contact Baer Brakes. They sell brake packages for the f-body that utilizes the same C5 (PBR) caliper. You might be able to pick up a set of brackets from them as an alternative.

If you use the Baer adaptor bracket, you must use their whole system. They do not offer an adaptor for the C5 front brakes that allows you to use the C5 rotor. Back in 1998, I called Baer twice asking them to design such an adaptor bracket. When they refused, I decided to do it myself. I concluded that they wanted to continue making money after the initial sale by forcing the customer to come back to them for (very expensive) replacement rotors. I wanted to be able to use inexpensive and universally available C5 rotors.
The Baer rotor they supply with their C5 front caliper system is larger in diameter than the C5 rotor, and probably a different rotor offset also, so they have to locate the caliper further out. GM High Tech Performance put the Baer GT+ system on their Thunderchicken project car. They seasoned the rotors, but the first weekend on the track, both rotors cracked all the way through. Baer sent them replacements that were a newer heavy-duty design. Those replacements were about 5 lbs heavier per rotor than the GM C5 rotor, and I believe their current rotor replacement cost is over $400/pr. The C5 factory rotors can be bought for $100/pr., but many racers use the NAPA C5 rotors for about $54/pr. Plus, if you or a future owner of your car ever needs rotors, they can be bought at any GM dealer or parts store. The Baer rotors can only be sourced from Baer.
I think Baer’s price is around $1200 for the system, and most who are using it seem to like it very much.
The “other” bracket was (is?) made by LG Motorsports. You can read one owner's thoughts and see his pictures of the LG bracket at: http://www.ls1.com/forums/showthread...5&pagenumber=1
That bracket could only be used with LS1 steering knuckles. And, the last anyone posted about it, it still could not accept the C5 Pad Abutment Bracket. It forced LS1 owners to “reuse” their LS1 PAB’s, which is not fully compatible with the larger 12.8” C5 rotor. Also, you have to do some grinding on the back side of C5 (or ZO6) calipers to make them fit. Also, if you want to use C5 pads, you have to grind on each set of them to make them fit.
The last 2 people that I have seen post about them said that they have not received replies to multiple emails asking for info and pricing. They are (were) not listed on LG's web site. I believe that the Baer GT+ system is a better engineered solution.

OK Bob you're killin' us! That doesnt sound like something I want on a car I road race. I'm sorry it has come to this, it's pretty clear how hard you work on these things, and how adamant you are about relieving yourself of this burden, but Bob, you simply leave us no choice... myself and my waitlisted conspirators are waiting outside your door in a black van with tinted windows. Yup, thats us. Come outside willingly and we'll give you plenty of food and water, and one phone call a day until the brackets are made. I'm kidding of course, we'll give you beer. Seriously though, if there is even the slightest chance you might make more sometime this summer - I'll wait. Thanks for considering it anyway-

- Could whoever is running the show give me some confirmation that I am somewhere on the backup list? Thanks-
