Grand Sport brake calipers

[Mystic ZR-1]

96 Grand Sport calipers:
We‘re all pretty familiar with the differences
on the front calipers, is there any real difference in
the rears other than being powder coated black?
Any ideas on the going $ these days, front and rear?

[G8nightman]

Just color diff on the rears good luck finding a pair of fronts.

[BigJohn]

On my 96 they were painted black

[ALLTHECAMS]

What is the difference on the fronts?

Fronts had “CORVETTE” in the casting. C5s followed this

[efnfast]

Fronts also had extra cooling fins, that may or may not have added a little extra strength.

They are thicker and stiffer in the area at the center of the "C". As a result they flex less than ZR-1 calipers. This gives them a sharper edge to the bite when applied hard and sharply.

Great to know. Thanks Marc!

There’s a full rebuilt set on eBay right now. Not cheap but correct.

Actually, really not that bad of a price when you consider
they come with powdercoated brackets and new pads?
Allegedly remanufactured by Lone Star Caliper, good reputation
and they’re at Carlisle every year. But, don’t think they are the “seller”?
Have concerns about the $1000 core charge ($500 front, $500 rear)?
That’s a lot to be hanging out there on the old credit card...
Some places really drag their feet on returning core charges.
I’m thinking about it... 🤔
Pros: Pretty and rare
Cons: No REAL technical advantage

I have Grand Sport brake calipers all around.

The additional information is very useful.

Thank you.

“Four similar rebuildable cores.” What exactly does that mean?

[Mystic ZR-1]

They want your old ones back for rebuilding and keep your $ hostage till they get them.

So really, these are 1700 dollar calipers because no one is paying 700 dollars for a caliper rebuild and pads. Rarity is unimportant if you have to already have the same damn part.

If you're a trackrat and you want better brake feel, you need:

1) '96 GS front calipers because, like Marc says, they are stiffer in the bridge part of the casting.
2) braided stainless steel covered Teflon brake hoses.

When I had Barney, that was my brake set-up and it definitely improved pedal feel.
