sn94-95 a arms on the 87

[Turd Tops]

I'm going 5 lug so i can put my 93 Cobra r wheels on my 87. The car needs ball joints right now so i'm going to R&R those when i do the swap. I have the spindles and all that good stuff. My qustion is can i use the 94 A arms? Plus is anybody useing the Steeda ball joints? The 94 a arms i have allready have the Steeda stuff on them. Any problems running 94 spindles and a arms on the 87's? I don't know if it matters but i will not be running 94 and up cobra R wheels. I'm useing 93 cobra R wheels. Thanks guys

No, they are about an Inch longer, stick with Fox A Arms!

 

[Mustang5L5]

They are wider.

You want to stay with fox a-arms

 

[Turd Tops]

How much wider? wider is fine because the rear axle is wider also. I'm trying to avoid the wide rear and skinny frt. I don't want it to look like a mail truck.

 

[Mustang5L5]

Wider the point you'll have serious camber issues.

The problem is not the wider A-arms, but the fact that the upper strut mount doesn't push out as well with the A-arm. You need an SN95 body for that

 

[Turd Tops]

Ok, that makes sense. Now the qustion is how do i get the frt end to have the same width as the back? I'll be useing an old 93 cobra rear axle. Spacers are out of the qustion also. I won't run them. Are the spindles on 93 cobras diffrent for the rest of the fox bodies? Oh yeah it all has to be 5 lug because i'm useing 93 cobra r wheels. So would just the sn-94/95 spindles work? The rear was out of a 93 cobra but was converted to 5 lug just the 93 cobra r was. any help would be great. I'm not sure what the 93 cobra r's used in the frt for brakes. any info on the 93 cobra r's would awsome.

The 93 R had the 94-98 Cobra brakes in the front, and I'm almost positive that it had the 91-92 Mark VII brake set up in the rear (rotors, calpers, and long lincoln axles). The '93 R had 10.5" vented rear rotors, and the 91-92 Mark VII also had 10.5" vented rotors with Turbocoupe/'93 Cobra rear calipers. I was looking for another way to convert my TC rear to 5-lug, but I somehow ended up engineering the '92 Mark brakes to work with the shorter SN95 axles.

I'm scratching my head now. I was lead to belive the 93 cobra and 87-88 Turbo coupe use the same axle and brakes. I was also told by some local fox body guys the are pretty knowledgable the 93 Cobra R was the same axle as the 93 cobra and 87-88 Turbo Coupe but with 5 lug. I found a guy downtown selling 93 Cobra/87-88 Turbo coupe 5 lug axles and rotors. They are the same length as the 4 lug axles from a turbo coupe but with no ABS ring. The rotors are the same also but 5 lug. All i started out with was a 93 cobra axle housing and gear set installed. No shafts or brakes. Also because of the people i got the axle housing from would lead me to belive it would just be a Turbo coupe axle. The reson i think "and was told" it was a cobra axle was because it comes with 3.08 gears and not the 3.55 or 3.73 the coupes came with. So now i'm just confused on what i have. I know the parts work because i put everything together and it looks fine so far. I have'nt but the axle in the car yet but i don't see why it would'nt work so far. At this point i don't care what i have as long as it works fine and stops the car. Now i just have to worry about the front. If it's as easy as putting on 94-95 brakes that would be cool. I just want the stance to be the same all the way around without useing spacers.

You're right about the TC and '93 Cobra having the same set up (axles, caliper brackets, calipers, 10'' vented rotors).
I'm sure that the '93 R has the 91-92 MK7 set up, if you look a pics of a '93 R the rear wheels really pop out just like a fox with those long Lincoln axles, the R even had a warning label about rear tire rubbing. The R and MK7 both have 10.5'' vented rotors... and I know for sure that the TC/Cobra/ 91-92 MK7 all use the same caliper; most people think that the '93 R has the 11.65'' disk that comes in the Motorsports Cobra brake kit.

I did a lot of parts swapping/mismatching between sn95/MK7/TC stuff, so I hope I know what I'm talking about. It sounds like you might have SN95 axles, I wonder what kind of rotor you have; whats the diameter?

The '93 Cobra R does not have the same brake setup as the 94+ Cobra. The interesting thing is the Ford M2300K's instructions say it's the same, but it's not.

I am 99.9% positive the '93 R runs the 1991-1992 Lincoln Mark 7 rear disk setup. That last 0.01% will be when i see an R in person to confirm myself.

They are 10.5" Vented rotors with a 45mm caliper like the t-bird/standard 93 cobra. I'm fairly certain all Ford Varga style rear disks use a 0.75" increased width each side to clear the ABS ring.

The front brakes are PBR's taken directly from a Corvette. The spindles are unique to the R

Technically, they were never the same.

The rear is slightly narrower on a stock drum-brake equipped mustang. How much i do not know.

The way Ford solved the increased track in the rear of a '93 cobra was to put a 0.75" taller hat on the standard 4-lug rotor. That pushed the front wheels out 0.75" to match the rear.

If you are running 17x8 '93 R wheels (94-95 tri-bars) then you'd want 94-95 spindles up front and any of the 0.75"(each side) offset disk setups out back will work

I don't belive thats true. I belive that the 93 Cobra used the same axle as the 87-88 Turbo coupes, Brakes and all. What i'm not sure of is what brakes where on the rear of thr Cobra r

I meant to say front rotors. Not the rear

Take a 93 GT front rotor and a 93 cobra front rotor and they are the same except the hat is 0.75" taller on the cobra.

The rear is a 87-88 t-bird rear on the standard cobra

I understand that the 93 Cobra used a taller hat on the frt brakes but that does me no go because there 4 lug.
I did a google search and found one pic of a 93 cobra r front brake and it looks to be the same as the 94 cobra.

It pretty much is.


It's only by some small technicalities that I say the '93 R brakes are "different"

They have unique calipers and the spindles are F3 spindles which only appeared on the R (and only 107 sets exist so good luck getting a set). I beleive the redesigned F4 spindles in 1994 featured a provision for ABS and a dust shield....but are the same otherwise. There is an F5 spindle, but unsure what the differences are. I actually have an F4 spindle on one side and an F5 spindle on the other in my car.

But for all intents and purposes they are the same

These are the unique calipers
