OK I'm really not sure why you want to upgrade to GT brakes. Its all about stopping distance right? So does anyone have the hard facts as to what the 60-0 stopping distance is for V-6 with standard brakes verses GT brakes on the V-6? Are we talking inches or feet here???? Or is it resistance to fading due to heat buildup that makes the GT brakes worth the extra expense? Or is a macho thing?

I don't know if it makes a real difference or not, that was part of my original question. From my point of view the package (which does include the mounting brackets, thanks for tip GrayPony and bigcat) isn't really all that much more than a set of good pads and having my rotors turned. Since I have the larger wheels already, if it helps, then why not, if it doesn't, then I'm better off putting some decent pads on and waiting until I can afford a full aftermarket upgrade package. Of course, part of “why not” is always will it even work, which I think we got some good answers too. Thanks to everyone that provided input.

ok so read a post just now about gt caipers use an offset bracket for the bigger rotors. i bought gt rotors and didnt even think about the extra inch. so does anyone know where i can get a offset bracket or whatever to make them fit?

First off the front and rear calipers on the GT and V6 are the same. The only difference between the gt and v6 is the front rotor diameter. The GT rotors are 1" larger. Cars equiped with ABS/TC have no prop valve (this includes all gt's which have abs standard so no gt prop valve is available). the use dynamic rear proporting (DRP) which uses the abs to control the the rear brake balance based on the front/rear slip differential. This system is much more effective than any prop valve and can dynamically adjust to lood conditions and deceleration levels.

Non-ABS V6 cars do have a prop valve. The base brake balance is close enough to neutral, and the critical point is at .85g that you don't really need to worry about proportioning with the gt brakes. If you add the larger gt rotorsthe bias will be shifted slightly toward the front so your balance shouldn't be a problem. On the other hand the gt brakes are really not going to make that much of difference to the v6. Replacing the tires will have more of an impact on braking.

If you really want to improve braking, you need really sticky tires, and some aftermarket brakes, with bigger calipers and rotors. Be careful how big you go because you may need bigger wheels to clear the brakes.

So, if I understand that correctly, the ABS controls he brake bias then??

why would i want the extra $200 a month in insurance? If you want to pay it for me, im more than happy to fork over the extra $80 a month for the car payment.

Are you serious? I "own" both. The insurance isn't much different. My girlfriend has about the same driving record as myself and her insurance is only $20 cheaper a month, not even close to $200.

I put the GT takeoff rotors/calipers/brackets on the V6. Seems to me it stops better, and it surely didn't fade as quickly as the standard brakes. For me, very much worth the cost and hassle. Balance was not an issue on the street or autocross track.

Took me a while after I started the process by "winning" an auction from the eBaY newtakeoff/Diversified Industries outfit. They had/have a good reputation with most folks, but they acted like crooks, with me:

v6 to v8 brakes

hey, no there are a few of us who know what a proportioning valve is. but it is the issue here. I converted a v6 car and used 20" wheels on it, direct bolt on! no issues with the brakes or abs. Any v8 will do, just make sure that if your car has ABS, make sure the v8 car does too. if you do not have ABS, then any brake will fit.
no special tools, just bolt the stuff in. You may want to upgrade your rotors and pads like i did. goodluck
