Vette Z06 Brakes on our G8

[human29]

Saw somewhere someone had put the Z06 brakes on the G8. Anyone know how this was done, is there a kit?

I fixed your title :)

[roSSco]

That would be an awesome conversion. Much cheaper that other alternatives. Would require different wheels though. ;)

[confused2much]

That would be cool to see at least.

It would not be much less than a Baer kit... the calipers alone are going to be $600+ plus the rotors, an adapter...

If this is the case then I would rather have Baer brakes. While the Z06 would be cool to have I think the Baer would perform better. Brakes are what they do for a living.

Have you ever looked at the stopping distances on a Z06? Hmmmmm......

Be interesting to see how they'd go pulling up 4000 pounds instead of 3160 tho.

Really shouldnt be much difference. If I do/did it, I would get a different brake pad to compensate for the heat from the extra weight.

[clukefl]

The builder "Tjin" is a member of the other G8 forum. He stated when questioned about the brakes:
"They are the C6 Z06 calipers and rotors.

We had to make all new brackets, shims, and redo the brake lines.

The front's weren't to bad, but the rears took about twice as long, especially keeping the e-brake functional.

Here are some pics of the front calipers and rotors installed.

Actually, they are less dependi ng on where you look. I like to buy from GM Parts Direct online. I just priced them:

$228.37 a side for the front calipers.
$228.37 each for the rear calipers.
$98.99 each for the front rotors.
$76.13 each for the rears.

I bet you can get the whole thing done for under a $1500.00 if you try. Hard part is the brackets.

[human29]

I would like to see if someone could make those brackets, I am sure he could sell a few.

[mjduell2009]

I would be very interested. I don't have time or I would do it. This seems to be a very cost effective way of doing a nice brake upgrade.

--Mike

[99-LS1-SS]

Out of shear laziness and not wanting to research right now, how much of an upgrade is it? What are the main differences in the two brake systems?

Get back there and read the thread! LMAO

[mjduell2009]

C6 Z06:
14 inch fronts (cross-drilled)
13.4 inch rears (cross-drilled)
6 piston front calipers
4 piston front calipers

http://www.corvettegarage.com/images/products/full_size/c6-2002.jpg

I beleive the G8's are:

12.64-inch front
12.76-inch rear

Both calipers are 2 piston.

--Mike

[mjduell2009]

Just thinking out loud, but this almost sounds like a GRRRR8 mod :cool: Very few of the rest of us hacks could pull it off.

Listening Charlie?

--Mike

[GRRRR8]

Yes Sir! I am looking into the brackets or who can make them. I dont care that they say Corvette as from day 1 I have called it "my 4dr Vette".

[-Ray-]

If someone can get me a cad file of what the brackets need to look like, I'll get some fabbed up.

[mjduell2009]

Yes Sir! I am looking into the brackets or who can make them. I dont care that they say Corvette as from day 1 I have called it "my 4dr Vette".

Please put me on the list for a set of brackets. Don't care if it takes a year. I would be very interested. Don't care if they say "Corvette" either, kind of gives the brakes a little extra street cred.

--Mike

[99-LS1-SS]

Since the GXP and the Z06 both have 14" front rotors would they be interchangeable?

This mod would be nice for the back brakes but seems like a lot of work for minimal gain on the front brakes for the GXP. What do you guys think?

After looking it seems like the rotors are the exact same diameter and thickness on the Z06 and the GXP. I would buy the Z06 rotors.

[Andy@Livernois]

I say just put the GXP brembos on it and call it a day... While the ZO6 components are nice, I just think the Brembos will do such a good job you will be happy for less money...

[99-LS1-SS]

I agree with Andy. Just add the Z06 rotors and you should be good. Unless you plan on auto-crossing it doesn't seem worth it to me. But, everyone is different.

[mjduell2009]

I agree with Andy. Just add the Z06 rotors and you should be good. Unless you plan on auto-crossing it doesn't seem worth it to me. But, everyone is different.

I guess the question would be, what would the cost of the GXP brakes be? How many piston are the calipers? For me that matters because I open track and Auto-X my car and have built it with that in mind.

--Mike

[Andy@Livernois]

brembo calipers are 4-piston... I don't think anyone knows the cost yet. I think you will be more then happy with the brembo...

[mjduell2009]

Depending on cost versus the Z06 set-up it does seem like an option. Have to wait and see.

[Andy@Livernois]

I am waiting on word back from brembo...

A lot of the Z06 guys that track them are moving from 3 separate pads (per side) to one big pad for the C6 Z06.

[Andy@Livernois]

well, brembo says gm has exclusivity on the system... I guess we will ahve to wait for the GM part numbers...

Dont forget brake pads, lines, brackets...ect... east another $150 per corner. And stock vette rotors will not fit so you have to look for custom or blank rotors and have them drilled.

[99-LS1-SS]

Speaking only about the GXP, the rotors on the Z06 are 355mm in diameter and 32mm thick. The GXP rotors are the exact same dimensions. If the part that slides over the studs is a different depth then I can understand but if it's the same then there should be no reason they shouldn't work. Does anyone have this information? Thanks.

What do you think the guy in the post did? Did he drill out the holes bigger or did he change out the Hubs for Z06 hubs to use the factory rotors?

[GRRRR8]

They have the same bolt pattern, but the G8 studs are bigger, no biggie to drill them out.

[danno111909]

Those pinstripes really piss me off but those three gauges up to made it all better!

[r33pwrd]

just got pricing and part # on the OEM GXP stuff today... :) about 1K for the front but that was from a normal pontiac dealership with big markups. Problem is they say atleast 1 month out.

[GeorgeInNePa]

PM Greg@Pace those part numbers. I'll bet he can give us a nice price.

[r33pwrd]

will do... I just wish I new they would not have clearance issues behing the stock 19's.... but if not looks like I will go bigger grakes.

fyi

calipers 346 each
rotors 161 each
pads where 181 pair (parts guy was not sure if the calipers where loaded)

also would need brake lines but I would want to get SS so oem ones would not be ideal for me.

[r33pwrd]

honestly from my history with brakes this is not always a good option. The rotors (unlike the wheels) uses a center hub to center. This being said if the hub is a different diameter on the vette you would either need to machine them bigger or use a centric ring.

[GeorgeInNePa]

It just hit me, if the part numbers are out for brakes, they should be out for the gears also!

[r33pwrd]

probably but they have to go back to GM for pricing and avalibality. They told me brakes could be as little as 3 weeks and as long as 6 months??

[Greg@PacePerformance]

LOL you guys. I have had the part numbers for the calipers for about 3 months. :) I also have GXP rotor part numbers. You guys just have to ask. The prices could change but this is the standard 20% over cost for forum specials. Packages will lower prices.

We also have the 2010 camaro catalog and I am putting together packages for HID headlight conversions if I can for the guys that want them but don't want the RS package. ;)

how long for you to get them?

[Greg@PacePerformance]

My experiance has been that GM will not release the parts until the cars have hit the streets to make sure they have enough parts for production.
Sorry it might be quite some time until we see them but I keep checking every month.

Many reviews have said there is a ball joint on the knuckle instead of a bushing. I'll bet there is a different control arm too.

[Greg@PacePerformance]

Well now after looking at my part numbers again in the parts catalog it is not listing a different knuckle for the GXP. The number is still a good part number but in not in the system any more. hmmm.
It does list a 2009 1/2 ball joint change for the rear.

[vipz28]

So are the mounting brackets different from the GT to the GXP? (I assume so, but ya never know) or is this going to be a direct bolt on?

If the fron hub is the same price than they should bolt up...

[Greg@PacePerformance]

Everything I have found says they will bolt right up.
You will need new rotors, calipers, and pads. Nothing else seems to have changed.
We will know soon! We have a willing party wanting to be the first conversion.

I have front rotors, calipers, and pads on order, but the calipers are on backorder and the rotors are not available for sale yet. :(

You have 2 parties wanting to be the first. I'll rock paper scissors them for the honor :):)

So that would be around $800 plus shipping, for the front Brembos, not bad.

What about the caliper brackets, are they the same?

If it follows the camaro (I haven't looked at the brakes on my GT yet) then the calipers mount to tabs on the hub. If the hubs are the same from GT to GXP, then they will bolt right up.

vipz28 is correct. The calipers mount directly to the hub. No brackets needed. Rears are the same also that is why I orginally thought you would need new knuckles also but it seems that is not the case.

Let me know when the pads, calipers, and rotors for the front are available, and what your "package price" will be :secret:

[Greg@PacePerformance]

I'll keep you posted Vipz28.

[MtbDoc]

Sign me up as well...and please clarify (alright, I'm too lazy to look it up):

- Do we have the same rear brakes as the GXP?
- Is there going to be any sort of ABS computer glitch?

I am assuming NO to the above as we are discussing the swap...but just want to make sure.


And Brembo isn't a sponsor...so go ahead and ban me!

[MtbDoc]

Wrong board.


Yeah...I realize...I simply forgot the :)

[Greg@PacePerformance]

I am not sure about the rear brakes yet. GM is really slacking in the parts catalog department. They do not list a rear caliper for the GXP so I am guessing it is not the same as the GT. They do list different rear rotors.

I can also get the ZO6 calipers if anyone want to go that route but you would have to make your own brackets. I can only supply the stock parts.

I've still got to burn up the stock brakes (first autoX is next sunday) so I've got time to wait :zing:

[DRCUSTOMPARTS]

The brakes are more than sufficient on our car, I'd rather put the money into some go fast goodies!

[MtbDoc]

My thinking exactly! See what happens over time, and then the braking upgrades will be sorted out.

With my GTO, I started buying parts BEFORE I EVEN HAD THE CAR! Trying to move more slowly this time around...

...but this GXP upgrade seems VERY cost effective.

[sccaGTO]

I suppose I should keep my eyes open in the Camaro section.

[dklau33]

I'll keep you posted Vipz28.

Greg,

Please keep me posted too. If these GXP front brembos are a direct fit for the GT and we can get the entire front package for under $1000 then I'm in. I hate how the stock GT brakes lack some feel and are a bit soft. I've been spoiled by Stoptech's for a while now so I would love to shore up the brakes on my GT.

[BSmith]

For the Z06 upgrade...

Someone with stock wheels might want to download this template.

http://www.kore3.com/downloads/fitment_templates/DOC0019.pdf

The caliper sticks out 1.69" from where the wheel mounts to the rotor. I don't have stock wheels anymore so I'm not sure if our offset would work for that.

I like to go fast. But I like to stop just as fast and nooo fade :) For a grand its a great investment in keeping my frontend happy! :)

So I printed out this template you posted along with the Baer front 6-pot caliper for the G8. On my stock 18" GT wheels that have an offset of +48 the Baer caliper fits just fine as expected. The Z06 caliper however does not even come close. I think one would need some wheels with a very aggresive offset to make this work. From eyeballing it probably somewhere in the low +20's or more.

So don't think we will get enough clearance with the right spacer and still fit under the fenders?

I'm not too sure about that. That would be a trial and error thing.

Why would a low 20mm offset help? That brings the wheel under the fender more, but it doesn't change where the Caliper would hit. We would need both a conservative offest (38-48) but more of "facing" difference between the spoke and mounting pad.

Assuming you're using a wheel that is the same width as stock, 8 inches, then a lower offset would push the wheel further away from the car giving the spokes more clearance from the caliper.

[Ktlplxm]

Assuming you're using a wheel that is the same width as stock, 8 inches, then a lower offset would push the wheel further away from the car giving the spokes more clearance from the caliper.

Not always. Unless the front lip-to-face spacing remains the same the 20mm would only push the wheel face out. When most aftermarket companies move the offest by almost an inch, they move the entire center piece inwards, they don't just add material to the back of the mounting face. Well, at least the good companies do not. Some of the cheaper brands such as Eagle alloys do accomplish it in the way you described, so I can see your point on that

[BSmith]

I didn't think the Z06 caliper would fit under the stock wheel. We had one at the shop a couple days ago, some guy trying to sell them. I did fall in love, but I could tell it just wasn't going to work out. :(

[vipz28]

I'll keep you posted Vipz28.
Any progress in the parts department?

[Greg@PacePerformance]

Still waiting on the calipers. It seems GM is using all available parts. I have a SPAC case open for them and will get them as soon as GM has a spare set. I still can not order the rotors, YET.
-Greg

[dklau33]

Greg,

Would you have any clue if these GXP Front Brembos would fit under the OEM 18"s on the GT? I assume they would.

[Greg@PacePerformance]

Sorry that one I won't know until someone with a GXP test fits a stock 18" wheel.

The dealership had to order a brake sensor for me... 3 times. The first 2 were damaged in shipping... Then they ordered a new door panel for me... Sure it enough it came in beat to hell too...

At this pont I'm glad I don't own a GXP with a siezed caliper problem. I'd be waiting months for my car :spank: BTW I just ordered the royal purple GRRRR8 deal this weekend. Hope to get it some time this week. (thx Greg) I thought there was a mag plug option as well. What happened? :huh:

[bigtreepu]

I think it probably got removed due to the plugs not fitting the new 09's. The fellas think they used a different thread pitchy....just a hunch. I'm sure Greg @ Pace can answer for sure....

One of the front calipers have arrived. I am still waiting for the rotors to be released for sale and waiting for the other caliper to come off back order.

I took the magnitic plug off of the order page for the oil because it seemed more and more people had the different oil pans and this plug was not the correct thread. Sorry
