You can buy the lugs separate, but make sure that Mustang rotor has an integrated hub or you'll be SOL. You will need to convert your front brakes to 11" to use commonly available parts (including Mark VII rotors). This involves new spindles, calipers and front brake hoses. The Mustang rotor (or a Lincoln rotor) will not fit your 10" spindle.

can you explain what is a spindle and the pur pose
the rotoers are of an 95 or 96 mustang what are my chances is there any way for me just to change the rotor and thats it instead of doing all that other shit'

The spindle is the thing that holds your caliper and rotor, and is connected to the strut, ball joint and tie rod end. It is basically the thing that ties your front suspension together.

The 94-95 Mustang rotor will not fit your car unless you get spindles, calipers, and hubs for a 94-95 Mustang. All pre-95 Fox cars (including ours) have a rotor with integrated hub (the wheel bearings go inside it), while 94+ Mustangs use a separate hub and rotor.

Your best bet is to get spindles, hoses and calipers from a 1987-93 5.0 Mustang and use a pair of 84-92 Lincoln Mark VII rotors.

And, not to be an ass, but this is yet another topic that's been covered many times including a full tech article on Coolcats:

Yeah, it's called a Ford Ranger....Gen 1 & 2 IIRC (maybe even Gen 3)

how about will 10'' slotted rotors from a 79 to 86 mustang or 87 to 94 cyl mustang fit a t bird

05-27-2005, 10:07 PM
10" rotors will fit, but the problem is, theyre all 4-lug

If the one you're about to install is from a 79-93 Mustang it will fit, but it will be four lug. You cannot simply add a lug. There are no Mustang-specific, 10" rotors with five lugs. If a Ranger rotor is 10" and five lug, and if it has the same offset and wheel bearing size as a Mustang/T-Bird 10" rotor then and only then will it fit with your stock spindle, caliper and such. You cannot install an 11" rotor without changing the stuff mentioned earlier. It will not fit. And you cannot install any 94-04 Mustang brakes without using the complete system from that particular style (for instance, if you want to use 94-95 style you must use 94-95 style rotors, calipers, spindles, hubs, bearings, and possibly the control arms but I'm not sure at all on that part).

The only Mustangs with five lug rotors were the 84-87 SVO (11" I believe) and the 94+. All other 74-93 Mustangs had four lugs, and those slotted rotors you're looking at would have four lugs as well because they're designed as a stock replacement for Mustang rotors.

Ahem...once again...


10", 5-lug, bolt-on front rotors. Roughly $130 US shipped to your doorsetp.

When I say "Mustang specific" I mean "stock on a Mustang". Those slotted, drilled rotors that I think he was asking about (you see 'em all over eBay) are four-lug

I can't find any part listing on that page, Eric - when you click on "Products" it simply shows you that they sell certain parts (rotors, pads, etc) but not specific parts. Are these 10" five-lug rotors made just for the Mustang, or are they something that could be cross-referenced and probably bought cheaper (as a "stock" part for a certain vehicle rather than an "upgrade" part for a Mustang)? $130 for a pair of 10" rotors seems awfully high...

These are Mustang-specific. Several people I've spoken with have ordered them...they said quality is very good. The owner of this shop found me out of the blue to tell me they had 10", 5-lug, Mustang-spec rotors in stock. I don't think he's ever had them listed on his site, but if you call or e-mail they will provide the info for you.

From my 4-to-5 Lug Conversion page:

Stock Rotors (10")

Recently I was contacted by Brian Portez of Complete Brake Service in Columbus, OH. Brian says that his company has 10" 5-lug rotors for the Fox Cougar/Thunderbird (and Mustang) in stock for about $120 US per pair. This is about the only place that has come forward about these rotors and the only place I've ever heard that carries them. They'll even ship the rotors anywhere. The price ($60/each) is very competitive. You can visit their website here or you can call 1-800-581-2339 (locally 614-221-4888), and ask for Brian.

Jason from FL writes: "Just installed the 5-lug 10 inch rotors. Fit was perfect, quality seemed excellent. Price was good at $129.00 U.S. plus shipping. I got rotors, new inner and outer bearings, seals and dustcaps. Shipped to my door in 3 business days. Thumbs up from me!"

Yeah, it's a little high in price but honestly, where else can you get them?

Thanks Eric....I knew I saw that place somewhere. I thought they had a post on cougarnuts. It musta been on your site though.

Eric, I belive I read in Hot Rod Magazine once that Aerostar front rotors MAY be a direct bolt-on. That would still be the 10" rotor, but have the 5 lugs. Perhaps it is this beast that is being touted as a "custom" brake part, the lowly aerostar rotor?

06-13-2005, 08:08 AM
I dont think it is the same bolt pattern as mustangs, which is what most of us want. http://www.discountedwheelwarehouse.com/Ford_2___Vehicle_Bolt_Pattern_Reference.cfm
they may work. I have heard of mustang guys useing ranger and bronco II rotors with lots of mods. They are both listed under the same catagorey.

06-13-2005, 08:53 AM
The Ranger and Aerostar have deeper spindles, requiring a very different set of bearings. This much I know for sure. I've seen the Ranger/Aerostar rotors listed as 10.25". I've not seen them as plain 10" rotors.

06-13-2005, 09:37 AM
ive been told by stang boys that the ranger rotors work, but whenever i say "could someone send me pics" or "id like some physical proof", they just told me to go to some website, so i can confirm how true it is

even though they are 10.25, you think that there needs to be about 1/8" clearance between the rotor and caliper bracket for them to clear
