i have a 4cyl mustang to do my swap

the rear end in it is a 7.5 so am looking at a sn95 ( 94-98) rear w/ disc brakes

whats the different between the 87-93 8.8 rear and 94-98 rear cobra or gt besides the drum brakes ????? i could do a disc brake swap on the 87-93 8.8??

and if i do this swap do i have to use the sn95 or fox body rear upper & lower control arms and shock ?????

will the aje ls1 k-member fit on the 4cyl ???

i also have the chance to get the sn95 front spindle and cailper, rotors. does it matter if it a gt or cobra. do i need to use the shock & lower control arm from the sn95 on the mustang and does the lower control arm fit in to the aje k member

forgotten

I believe the sn-95 rear end is 3/4 " wider than the fox body rear end. I am planning on doing this exact same thing so be sure to list your swap and your discoveries. Mustang forums might have more info on this stuff.

The sn95 rear is wider. I think there is a swap kit out there to use the sn95 disc brakes on the 87-93 rear. The upper and lower control arms are the same.

Yes, the AJE LS1 k member will fit the 4 cyl. car. The frame mounting positions are the same on 4,6, & 8 cyl. Mustangs.

Check out www.Corral.net for the disc brake swap.

I have a friend that done the exact disc brake swap. I'll email him and find out what he had to use. Hope this helps.

so i can use the sn95 upper and lower control arms and shocks on the 4cyl mustang???

you should be able to use the same shocks and uppers and lowers and if your putting an sn95 rear in it you'll have 5 lug on the back and 4 lug on the front. if you do that you can use gt 5 lug spindles and gt brakes and lincoln mark 8 rotors and youll have 5 lug all around

All the uppers and lowers are the same and have the same mounting locations. The shocks also have the same mounting positions. Length of the shocks i'm not sure about. They should be the same though.

North Race Cars makes a custom mounting bracker to use the SN-95 Disk brakes on the Stock Fow Length axles.

These are for Cobra brakes

These are for GT Brakes

i was planning on getting these since my wheels are out too far with the 10.5's on the back... do i need to run the ranger axles with this or what?

wheelies247

LES SS your car looks fu*cking sweet with the 10.5 wheels out like that. fits with the fender real nice

what size tires are you running on the front and back? 4cyl springs all the way around???

if you launch the car to hard will it hit the fenders in the rear ??????

would i have to change the master or booster with disc brakes all around or could i just run the 4cyl set up


LES SS
do you stay with the 4cyl set up??

wheelies247

LES SS

on your swap did you use the sn95 rear upper and lower control arms or the 4cyl ???

on the front would i use the sn95 or 4cyl lower control arm ????

Coreyc619

you have to change the master cylinder to a 93 cobra for the discs.. and add a proportioning valve.. usually a good spot is the PS firewall. or thats one of the easier routes to go..

dont think of using the PS rangers axles theyre weak as sh*t. GT brakes would be much easier to fit a 15" skinny drag style wheel up front.. just buy some decent axles.

if your gonna do a drag setup id recommend using c-clip eliminators

wheelies247

weres a good place to start looking for the proportioning valve

regulate front and rear pressure ??

Like I say, check out www.Corral.net. Or try an ebay search. Either should bring up some parts for ya. Good luck on ur swap. Keep us posted.

wheelies247

what does the proportioning valve really do and how would it help with my braking is it an adjustable valve ????

mg98ta

iTrader: (20)

Yes, it's an adjustable valve that adjust the pressure between the front and rear brakes. Too much pressure to the back brakes causes the back brakes to lock up sooner than the fronts. Hope this helps.

You will use the same length axles that you have but just five lug

28 spline is factory

http://www.latemodelrestoration.com/...0%201&comp=LRS

Or you can upgrade to 31 apline

http://www.latemodelrestoration.com/...0%201&comp=LRS

You will have to run a master cylinder designed for disk brake applications

1993 Cobra is the easiest but you can modify others to work as well, as far as proportioning valves go..most people I have seen mount a small willwood adjustable valve on the rear line that runs across the top of the firewall. They just replace the connector with the valve.

at first i was runnin cut 4cyl springs that had been cut before the swap. but the tires would rub bad in the back.. so i put stock 5.0 springs front and back and the front fender gap was like 8 inches from tire to fender. so i cut 1-3/4 coils off the fron and left the rear 5.0 un touched. its rides pretty good with that setup now too. not bouncy or anything of that nature..

i havent changed my booster or master yet.. you dont have to change it asap to drive the car but to get the best out of the brake swap its good to change them..


on the rear i used my stock 4cyl control arms for now, they bolt right up. in the front im using 87-93 aje tubular control arms. but you can use 4cyl ones if you want. its just harder to get the camber settings in spec with 87-93 control arms over the sn95

i already have cobra rear with cobra brakes so the gt ones are outta the question... but my question is what axles do i need to get to get back to stock track with that will work with the cobra brake bracket. i know i can use ranger axles but i want to get some 31 spline axles and tru trac in the future
