05 Mustang 13" rotors fit MM?

[69mach1]

Hi all,

I'm trying to find out if anyone's checked into the optional 13" (or larger?)rotors on the 05 Mustangs if they can be adapted to our MM's. I ran across this ad regarding an 05 Mustang Baer brake upgrade using larger rotors and a bracket to move the caliper without replacing the caliper. I was thinking we could put the larger front 05 rotors with a similar machined bracket.
Food for thought...

Ps. Not trying to sell a Baer product, just showing a style that might work.:cool:

New from Baer this 13" rear upgrade kit fits all 94-04 Gt and V6 and offers superior rear brake stopping power along with great looks!
The rotors are crossdrilled and slotted, aswell as zinc washed, the installation is simple you do not even have to bleed the brakes, in fact you do not even open up the brake lines. Installation is a snap, simply unbolt your stock caliperand bracket, remove stock brake rotor, install the new baer brake bracket, install new 13" rotor, bolt on old caliper and bracket to new Baer braket and thats it !
should take approx 1 hour !

Those look really thin...and not vented? Although what are those, cross dimples? I may be seeing wrong.

I just showed this ad for the brackets. not the rotors. The rotors do look like solid but that's not what I'm after. I want to use the big beefy factory rotors with brackets like these so the upgrade doesn't cost $1600 :rolleyes:

My 2 cents

IMHO, a 4500 pound automobile needs brakes that can stop a 4500 pound automobile. Likewise, it needs suspension that controls a 4500 pound missle in traffic.

Despite my background of eagerness in trying new stuff for the MM, I'm not eager to experiment with this "upgrade".

Baer's got a good brake kit, so does Reinhart, ToddTCE, Wes Chain and other vendors here. Likewise for suspension goodies. Ummm...They work together, eh?

Why toss the dice for the few bucks involved? I'm sure that if you looked at all the options available here, you could find a brake system (and suspension) that meets your needs, financially and safely.

For every dollar you spend for horsepower and torque, spend 25 cents on stopping, and 25 cents on control. When you drive fast, you have to stop faster, and control it all the time.

Shocks, brakes, suspension, I understand wanting to save a few bucks. But, get too cheap about it all, and all you get...Is what you paid for.

Sorry, not with my family in the car.

Haven't you already asked this here:

The answer, which would have been obvious if you'd looked it over a bit, is no.

The only way you can do this would be to take the new rotor to a machine shop and have them cut it down to about 12" for you. You can't simply put a larger rotor on a car. Not bigger in OD, not wider in width.

If you change either of these dimension you'll not be able to bolt up the caliper.

* Can it be "adapted" to the MM? The answer is Yes. It would be the Baer kit. But changing rotors leads to other issues such as piston areas and brackets. Hence the reason it costs more than the $400 for a pair of rotors.

I get it!!! No one has checked into the feasibility of 05 parts fitting the MM. :( The obvious answer to my question is no, and yes I did ask the same question in post #19 but wrongly assumed that it was buried and no one saw. So I thought a fresh thread might yield more folks looking and subsequent new information. Hmmm what could I have been thinking!?!?! I wish to improve the braking capability for my MM using factory Ford parts while keeping it affordable. I'm quite capable and when time allows I will check into it myself.

Regards,

Jon

I see Baer sells the bigger rotors and the brackets to move the calipers to correctly contact the bigger rotors.
Do they make it for the Marauder, if so I assume we can use the stock calipers.

Feel free to yell at me as I really don't care.

Sorry 69. Didn't mean to sound as if I was beating up on you. Too often on forums people ask questions over and over until they get the answer they wanted to hear. In this case it would have been the classic "I think it could be done with some work but I've never done it". Which of course doesn't mean anything at all! It's nice to know you do understand the reason why this won't just bolt on.

For those with a bit less mechanical vision, the issue is the mounting radius of the calipers will not work when fit to a larger diameter rotor. While on the surface a small 'caliper relocation' bracket seems in order this cannot always be done. The problem lies in trying to offset two holes that are only 1/2" apart. There's nothing to bolt too. The alternative it an offset mount to shift the radial line of the caliper. This can be done on some kits as well.

Taking it a step farther; you'll need the same hub bore, same bolt pattern same hat offset, and same rotor width to begin to make it work. Unless you change the calipers as well. At that point you're simply building a BBK someone has probably produced. What you may want to review is the mount center and radial mount height of the Mustang brackets and compare this to the MMs. If you find they are the same you'd next want to review the piston sizes of each caliper as well as pad sizes and locations. These items will havew an impact on your final project and it's bias. Simply adding a larger front rotor will shift this to the front.

The other thing I think you'll find a bit of a problem will be the cost. The one piece rotors are rather pricey from what I understand. I sell Baer/Brembo/PBR/SVT Cobra replacement two piece kits yearly to guys who speak of costly replacements. None the less, please let everyone know what you find on your investigation. And if I can be of some help to you let me know.

Hey Todd

Thanks for the clarification, this is one on a long list of projects, I'll pipe in when I have results one way or the other.
Thanks again for your insight. :beer:
