I put this combo together for a friend and thought you guys would like some more eye candy. This is for you big wheel guys, 18" and larger who want some big stuff behind the wheels. It's a true 14" C6 ZO6 rotor mated to a C5 ZO6 caliper, sounded like a perfect match to me and it goes together quite nicely. I don't know why the rotors are different color but they're the same part number. Nice lower priced option to the 6 piston stuff. Take a look:

whats big difference in performance from using the C5 Z06 caliper and the C6 Z06 rotor over the basic C5 Z06 caliper/rotor setup? isnt the rotor like 1/2 inch smaller?

either way that would be killer behind some 18's+

ebmiller88

Performance wise? Probably not much or nothing between the two. The C6 rotor is 14", C5s are 12.75". C6 brake rotors come in 3 sizes: 12.75" base model, 13.5" Z51, and 14" ZO6.

well 14 from 12.75 is a nice jump..alot more surface to grab so it might grab better. Z51 13.5 tho would probly be ideal....would that fit under a 17inch?
but fantastic job on the conversions!!

How come the 2 piston C6 caliper isnt being used? Save some money?

think they are the same

Could you weigh one whole side with spindle lines and pads?

I am curious how much heavier it would be than a stock setup. (41-42 lbs)

ebmiller88

iTrader: (7)

It can, I just bolted up a ZO6 caliper set that I have on hand. They both cost about the same at $100 per caliper or so new. C5 and C6 dual piston calipers will interchange.

I just weighed the setup and it comes in at 65# per side. The rotor itself is 27#, that's how thick the casting is. I'd compare it to the thickness of a Baer rotor as seen here:

Thank you...the Z51 setup will fit the 4th gen 17" wheels I have in the shop with a spacer but they won't fit 17" Ronal Firehawk wheels.

So if someone like me that had the C5 fronts already, wanted to go with the C6 ZO6 front 14" rotors, all I would need would be the spindle to caliper cage custom bracket, right? I already have 18" ZO6 front rims already too. Do you have any of thoes available? What is the 14" rotor part #? Thanks.


Ive also heard that the C6 ZO6 front 6 piston calipers will basicly "bolt on" to a C5 cailper mount? Is that true?

Squeak

Not to sound disrespectful or anything, I can appreciate the work that went into fitting the setup onto a 3rd gen application.

However, is it really necessary to have that large of rotors on a Firebird or Camaro when especially in involves adding about 25lbs of unsprung weight and rotation mass to the cars ride quality? These cars already have a harsh ride and this would further lower the sprung to unsprung ratio and even give a worse front end ride as it is. Thats a total increase of 50lbs unsprung weight up front- thats major.

14's would be nice on something heavy like a 6000lb SUV, but 13 max is plenty adequate for a 3400lb 3rd gen. Even the 3rd gen road racers are using the factory 1LE brakes fine (11.7" rotos and 2 pot calipers)

Or at least find a much lighter rotor to use. That HD 14" rotor is silly even on a lightweight suspension Vette unless it having to haul down the car repeatitively from 200mph @ LeMans or such. Use that HD vane and thickness of a rotor in a 12" and you'll do great for even road racing a 3rd gen- with about 15Lbs saving on each side.

wow!!!! thats hard to believe. my mom has a C5 and when she had the stock rims there wasn't much room between the rim and caliper.

so will the C5 bracket work for the C6 Z51's? how thick of a spacer is needed? I was gonna go with the C5 brakes, and us the 1.7" spacer from Skulte.

You would need the bracket and also a Z51 carrier (abutment) which is what I used. I used that so I could keep the bracket as thin as possible (IE closer to the hub area. The bracket it 1/2" thick). The Z51 carrier pushes the caliper out farther than C5/C6 base carriers do.The rotor part number is 19121787 and is for both sides. Do I have any of what available? I didn't get that request.

No offense taken, and I agree with you. You can go overboard with a modification, whatever it may be, and this is probably a larger setup than is practical for our cars. But you understand supply and demand and I built the setup for a customer per his specs, and another one for his '75 Vette. Odds are most guys won't run this but it does have one hell of a "cool factor". Find me another 14" setup for a 3rd gen, I'll say I have the only one like this which obviously can be improved with lighter two piece rotors and aluminum hubs which will raise the price of course. Personally, I run 12" 1LEs and 13" C4s on my cars which are plenty of brake, my '70 project will have C5s up front, all are plenty of street brakes.

If I understand you correctly, yes. C5 and C6 Z51 parts are very close to each other.

OH...I almost forgot.. I test fitted this setup today on an aftermarket 18" Iroc wheel (as seen on Ebay and the like) and it fit great. This wheel had zero offset and 4.5" of backspacing, you could probably get away with 5" of BS. I have yet to try the 17" 4th gen wheels I have in the shop but they'll at least need a spacer.

I just want to say the work you do is awesome! Much appreciated by the thridgen community. When the time comes, which may be far away, to upgrade the brakes on my car, I will be buying from you.

vorgath

It really depends, on your rims, certain rims show everything, hide nothing, heck show off them big brakes. I'll be picking up a set on Thursday, although it'll take a few months before I'll mount them.


Can you guys show a pic of that 6 piston assembly ? Never seen one actually mounted, just bare calipers in Summit and JEGs.

ebmiller88, so the Z51 carrier (abutment) allows the use of a 13.5 in Z51 front rotor? So if one was to use the 13.5 rotor all you would need is the Z51 carrier and rotors?

What I was wondering was if you had anymore of thoes custom spindle brackets for the 14" rotor? But now Im thinking I would rather go the Z51 route with the 13.5 rotors to replace my current 12.75 ones.

Also do you have the part #'s for the Z51 rotors and carrier (abutment) Thanks again!!

Is this a go? I don't think this question got answered. Hopefully!

It is a 100% bolt on. Vette guys swap em all the time

ebmiller88, nice work and I like your hub! Did you fab that yourself? I have the C6 ZO6 brake calipers/rotors on my car as well, though the car is still a work in progress. I still have to fab a bracket for the rear calipers, so it's going to get interesting. I'll start with designing a bracket from wood and then go from there, oh and I am using a stange 12-bolt rear diff., so the brackets I currently have are designed for the LT1 camaro calipers not the stock thirdgen ones. I tried to repost some pics but they are already in another thread, so here's the link:

Thank you, that kit was pretty much made from scratch.

As for your rear brakes, what flanges do you have on the rearend? Being a Strange, a stock set of PBR disc backing plates should bolt right up, no fab work needed on your end. LT1 rear discs are the same as those on '89-92 third gens so install should be totally bolt on.

For me to run the C6 ZO6 rear calipers would these backing plates work? I am not what you mean by what flanges I have? I can tell you that the caliper mounting bracket/flange is a one piece design that also holds the axle in (since there are no C-clips)
