I tried to open it, I think it needs to be on a computer or some specific type. Scroll thru all the pages if possible n check it out.

Here's a guy that used to make them as well after, idk if he still does or not. But I know there's another person who does too. Idk his exact name and email though.

This is the guy now, his names brian. You can email him at [email protected]

Now idk if they are a direct fit or not for the grand prixs. And I'm not going to tear mine apart and try it, sorry. I don't know if this guy will have an idea if they'd fit or not as well. Good luck!

The fronts do bolt up without modification on the g8 just like the grand prix. If you can somehow compare the knuckles from g8 to grand prix and figure it out. It's just winter here and I don't feel like ripping stuff apart just to see. Not to mention my rear caliper brackets are all stripped on my grand prix too.

 

[turbov6cav]

Whay did you open that file with?

 

[GrandPrix06GT]

Scroll through the thread man, that's all I did. Idk what type or how to open the file.

 

[turbov6cav]

Oh ok thanks man

 

[turbov6cav]

Well if anyone was wondering I looked into it and the G8 bracket won't work.

Inquiring minds want to know....why wont they fit?

 

[turbov6cav]

Because the holes for the caliper bracket on the G8 center to center are 4.698. Ours are 5.643

 

[GrandPrix06GT]

If someone can measure or knows the distance in the rear knuckles of the grand prix, I can measure it with a digital caliper of the brackets.

 

[turbov6cav]

If you look at the picture on the bracket it says how far apart they are and ours are 5.643

 

[GrandPrix06GT]

Here's mm but not centers


Here's how threads go

 

[turbov6cav]

Yeah that's around 4.3" so it won't work

 

[turbov6cav]

But what is the distance between the holes on the caliper. Closest to the middle?

 

[GrandPrix06GT]

It looks like the non threaded is for the cts v calipers. And thread for the knuckles

 

[turbov6cav]

I thought they all looked threaded in that bottom picture

Threaded is the first pic, the 109mm

Oh ok, I may have the machinist I know alter the file and make it work for us. He said he is willing to do a group buy.

In order to alter that dimension. Everything will have to be moved out a inch.
I assume the angle is the same between the GP and G8?
