I got a caliper bolt off a mustang in the JY the other day and noticed it had the same front calipers as our rangers....was wonderin if the rear disc would mount up the same to do a rear disc conversion?

here's the car couldn't tell ya for sure what yr it is 06-07 i believe.


front brakes.....

 

wrong backing plate bolt pattern on the 8.8 if i remember correctly.

 

eh thats what i wondering,,,thats why i asked lol!!

 

Not sure how the ABS would work out, but why not? Rangers have 8.8s, and Mustang GTs have 8.8s as well. In theory it should all bolt on, and with some running of the lines it should work. I imagine youll need a proportioning valve though and like i said, i dont know how the ABS would work out.

If they make kits to adapt 02+ Crown Victoria rear discs to fit on a 9 inch, this is easy.

 

The new Mustangs (05+) are independent rear suspension, I doubt it will be the same. The rear discs on an 04 or older will fit.

 

Is it a bearing size issue or what? Im sure someone makes brackets thatll make it work. I dont know 8.8s the best, but is it because they went 31 spline? IIRC, pre 99 Stangs had 28 spline axles too.

 

Nope. still SRA. Only the Cobras 99- 04 had IRS.

 

the flange bolt pattern is different. idk about bearing size.

the best swap is the 8.8 from the explorer. assuming you have a 31 spline.

as for the 28 spline, idk there are a ton of options if your not going to want a bolt on.

 

Ok cool. I only know the 9 inch has a different flange bolt pattern between spline counts due to the 31 and 28 spline models having a larger bearing or something. retainer plate studs are different sizes too. I wouldnt be shocked if Ford did the same thing with the 8.8. Hey, i think i have a backing plate off of a CVPI around here somewhere. If i still have it ill do some measurements and see if its the same. Maybe a CV brake setup will bolt on.

/useless info

 

yeah i have a 31 spline. i would just rather do the explorer swap instead of goin through adapters and what not...was just wonderin since that was sittin there.

 

i think it can bolt right on actually from a crown vic but i dont know all the specifics.

 

LOL looks like i asked a good question!! looks like we'll get some good info outta this thread!!

 

You CAN run 04 and older cobra or reg stang disc on the back of the 31spline...but it requires a caliper mounting bracket that runs like $165 from currie(i think?).

You can run 95-04 rear stang brakes(including cobra) on a 28spline 8.8....it's a complete bolt on minus cutting the caliper bracket to slide over the ranger axle on the backside of the axle flange.

check out dangerranger01's project log on mustang brakes on 28spline 8.8's.

 

Its 94-04.

Cobras are 12inch vented. GT/v6 are like a 10.5inch solid rotors. And yes, check out my thread, its an easy swap.

Here are cobras, viewed from the top of the right rear caliper and modified brackets:
