Hog, Will the 5.0 brakes work with the 17" factory wheels? I run them in the winter with winter tires on them, and 18s in the summer.

You know, I'm not sure. I didn't switch until after I upsized to the 19s I currently have. I remember a GT owner switching to 17s for the Winter too. I think I can find the thread to find out for you.

It doesn't look like the17s will work. Check this thread:

So Hog what is the difference like for you with the GT brakes?

So, I have no impirical evidence, but they do feel grippier than stock. I am sure there is a little less fade. Do I think I stop shorter? I would find it hard to believe simply because the stock brakes already had impressive stopping power. What I think these do for you is allow you to run harder longer with less ill effect especially if you go with better brake fluid. Would I pay $600 for them? No, I could have gotten a true BBK from a local dealer. But for $125 installed, I think it's a great upgrade. I probably could see paying under $450 installed if you already had to replace your pads and rotors anyway. But then all you really need is the bracket. You can buy any 13.2" rotor and really grippy pads. Does all that make sense?

There is also the aesthetic part. The larger rotors fill out larger wheels better.

I didn't realize the stock calipers were Aluminum,, I see someone states that in the thread that is linked above..
"The calipers on the V6 and the GT are identical (twin-piston 43-mm floating aluminum calipers). So, they use the same pads. You may not even need to mount the new calipers (Depending on the ,miles on your brakes), just use the bigger bracket with the slightly larger GT rotor." post 33

That's correct, you only need the bracket. I used the rotors and calipers since they were already assembled and it saved me time and labor. I needed new pads anyway so got them with the supplied rotors. I may go with lighter rotors once these are shot.

yah,, in the end it seems like the reason to do the GT brake conversion is that it is a bargain, your going to have to buy rotors one day anyways, you can be them cheap now, as I recall the rotors at AutoZone started around $35 each. So $50 a pair is a smoken deal. then if you turn around and sell off some extra parts you might just be ahead of the game. Of course this all depends on having big enough wheels to to accommodate the larger set up, and in the ended new wheels cost money, and larger wheels, tires, rotors and brackets will weigh more unless you pay up for lightweight stuff.
hmmmmm

Here is some 14" rotors and Brackets, $650 , Ouch, well ouch compared to some Roush take offs, though they prolly weigh a bit less the 12.4" rotors, in another product description for a similar product is claims the weight savings is 3-6 lbs per rotor.

So the Brembo Takes offs from Roush do seem like a bit more of a bargain at $1200 for front and rear, including calipers.. But if the OEM Calipers Really are Aluminum, how much weight are you saving?
I have to say I have not taken my calipers off yet, I havent touched them, but they look like cast steel or cast iron not aluminum?
