Hello!! I am planning on doing a brake upgrade to my Corvette soon. I have a 95 LT1, I am basically deciding between c5 and
base /z51 c6 front calipers. What are the differences between these calipers? Is there a difference in pad size from c5 to c6? I will probably make the swap brackets that bolt to the hub myself, I still need the caliper brackets though and it seems like it's hard to find just the front c5/c6 calipers with brackets. I've seen a few swaps done on c4s but if anyone has pictures please post them that would help a lot thanks!

I'm interested in this project so I'm following!

Thanks Glenno, I want to get yellow calipers, here is what I'm going for:



I really like the look of yellow calipers on sports cars like this LP640, I haven't found any pictures of yellow calipers on a blue c4 so it will be a surprise when done

Glenno

I never heard of an LP640?

You can always spray the calipers yourself!

Hope the link works.

Yea I was thinking the same thing, I seen a couple of places online that sell powdercoated yellow c5/c6 calipers but they only sell sets that include rear and have a core charge it would probably be a better idea to paint them myself, the picture is of a Lamborghini Murcielago LP640

The C5 C6 and C6 Z51 calipers are all interchangeable. They have the same piston size, same bolt locations, but the C6 design is slightly stronger.

These are C6 calipers for reference

I really see no reason to do this upgrade unless you track your car.

72MiuraSV

kubs, thanks for the picture, that looks amazing. What is stronger on the c6 brakes? I thought I read somewhere that the pads are slightly bigger and the caliper itself is also slightly bigger than c5s. I have a- molds so i'm hoping they will clear

They're absolutely a lot more bling than the C4 calipers.

Wilwood makes a nice kit, and you'd have better brakes than even the C6Z

How much $$$$

PLRX

They were recommended by RedLS1GTO, and they brake great. They
don't fade with the heat like the C5 brakes did on spirit driving.

Crepitus

1500 per end

What system is that?

Not even close...maybe for used take-offs. (EDIT: I see some sets are on Fleabay for that price...not too sure how, but they are new).

Try $4,500 for the complete setup from DRM...

Exotic Muscle has a similar kit with Brembo calipers for $2,300 front and $2,700 rear....

But for the money I'd rather go with a C6 StopTech kit for $2,600 from Exotic

http://emracingcorp.com/scripts/prod...?idproduct=928

That's 6 piston fronts and 4 piston rears with rotors...a very good deal new.

are the c5 and c6 rotors the same thickness as c4 rotors? I have aftermarket rotors that are made for a J55 c4 and I'm hoping I can use them.

As mentioned, the C5 rotors are thicker and the height of the rotor "hat" may be different between the two. The caliper abutment brackets that hold the calipers for the C5 may be hard to find (at least they were hard to find last year).

Wasn't 1995 the year when 13" front rotors became standard? If so, I would suggest trying different pads to improve braking performance. CarboTech has some good pads for both street and performance use. If the flexible brake lines are original to the car, replace them with some stainless lines and do a complete brake fluid flush. For street use, a good DOT3 fluid like Castrol LMA or the Ford Motorsports HD fluid works very well.

If you do go with a C5 front upgrade, you will need to use ZR-1 style wheels to clear the front calipers. The OEM "sawblades" won't work.

There was a thread some years ago that had a pic and dimensions of the custom mounting bracket for later C4's to allow the use of C5 front brakes. You might want to do a search for something like "C5 caliper bracket" or similar.

So J55 c4 rotors will not fit/work on c5 calipers?

ThatVguy

No.

The rotors are physically different.
