First off,

1989 mustang or 1981 mustang....

Second, can some one make me a parts list to do a rear 8.8 axle swap WITH mark VII calipers, ( besides finding a 8.8 from a mark VII...any one got one ?? )

Front brake setup using mark VII calipers, using slotted and drilled rotors, hawk pads, whilist stille retaining the 4-lug

Sway bar kits .... "Eibach Anti-Roll Kit for your 1989 Ford Mustang 4cyl "  they any good ?

Last but not least,

" Eibach Pro-Kit Spring Set for your 1989 Ford Mustang 4cyl "

Dunno about the other stuff, but are you saying you want a 5-lug Mark VII rear with 4-lug front rotors? Why???

If you just meant that you want a rear disc swap, you'll want an 87-88 Turbo Coupe rear. It'll give you the 8.8, traction lock diff, 3.55 or 3.73 gears, and the vented disc brakes.

The front brakes will require an 11" conversion if your '89 isn't already a V8 model. The '81 will definitely require the conversion, as the 11" brakes didn't show up until '86 or '87.

You'll also need a master cylinder capable of moving enough fluid  - either an 84-86 SVO unit, a '93 Cobra unit, or a 94-99 V6 Mustang unit. An adjustable prop valve would be required as well.

I'd do the '81, just 'cuz it won't look like everyone else's Mustang.

Well truth be told, it's an 1981 capri.

Still clean and all,

i am currently ploting using the 89 as a donor car for the dash board, and all the elctronics and such,

the 89 has my 2.3 in it now....but blown up ...so i might pull it, and start working on it when my jeep is done... ( if it's ever done )

the ..rear end question basicly was, i want disc, ..big disc...with out going 4- lug. ...

my massive over all plan for this thing....is a 2 person, daily driver, whilist being a weekend road track killer...

some one happen to know off hand a web site with a simple ..( keyword " simple ") 11" front brake swap ?? for the 81 ?

and where i can find an 8.8 from a T/C with disc allready ?!

and what else ? a master cyl. from a T/C too ..right ??

Truth be told, I like the older Capris better anyway. Everybody has a stang. A sweet Capri will be admired by all, just because it's different.
 
As for the rest...
 
Like I told someone else a little while ago, pick one thing and stick with it 'til it's right. Pick a direction and focus on that. And KEEP your focus on that.
 
Four lug on the front and five on the rear? Hell, I have enough trouble finding wheels I like for either. Finding MATCHING wheels for both is going to be a major pain in the arse. And different wheels front and rear just looks half assed.
 
Going to a Mk diff on a stang (or Capri) is going to set the rear wheels wider. Your clearance issues are going to be compounded because you are going to have to watch your clearance on the lip of the rear wheel wells.I'd look at SN95 rears first for a better fit. That aside, I hace seen 295/50-15s on many mustangs with no clearance issues using stock rims. From there you just heve to work out tire size and rim offset to get them right. This thread will help with tire sizes going to different size wheels:  http://www.foxtbirdcougarforums.com/showthread.php?t=11099
 
If it says Eibach, it's hard to go wrong. Just remember, when you lower it you are going to run into other clearance issues and I don't mean just tires. Be careful how far you lower it and be prepared to change the way you drive for it. It's embarassing dragging your tail pipes off pulling into your SO's driveway.
 
Hope that gives you some insight.

The 11" brake swap IS simple...

All you have to swap is the spindles and everything attached to them. Struts (well, not a must but if you keep the old ones you have to use spacers), rotors, calipers, and make sure you have the rubber brake line that goes from the caliper to the frame as it's different as well.

The hardest part is getting the spindles off the ball joints.

Also if you really want, there are 5-lug rotors available that work with all the other stock brake hardware.

Thanks for all the killer help !!

I wanted a 4-lug rear end with disc brakes, i just meant a caliper swap,

i have a complete set of the " pony " 5 star rims, for 4 lug, so i'd like to maintain the 4-lug, and get an 8.8 rear end with disc and do a bigger disc setup in the front,

i was kind of curioius about some other options on lowering, cause like you mentioned, i can run into some issues,

Any one know any that ar more or less a better spring " " .. but not go to much lower ..

295-50-15 ?! would be the same on a 16 " rim too or no? ??

which axle is going to be a hair wider ? any 8.8 ??

a little wide axle is all i'd need to go with a much wider tire in the rear,

Thanks for all the help guys ...

BTW it's a capri RS .... weith an original I6 ...that died ...ever so softly :D

1" shouldn't really interfere, as that's a pretty small amount to lower a car. But I think you might have a hard time fitting a 295/60, that's a pretty big tire...

Also, Turbo Coupe rear axles are the same width as SN95 axles with rear disc (about 3/4" wider than stock on each side), and '99-05 rear axles are even wider than that.

A 295/45-16 will give you close to the same diameter and width as a 295/50-15.

If you replace the engine with anything other than an I6, you'll need to swap the engine crossmember. The I6 K-member is totally different from any other Fox K-member. Just FYI, I didn't see what your plans are for the engine. Anything special you're building?

i'm not 100% sure about that, i was told that all i'd have to do to swap in a V8 was use the same motor mounts, but on the oppisit sides

either way, a k- meber swap can't be all that hard,

the motor plans are in the engine tech thread.

If you're wanting to keep your stock a-arms, with regular springs I presume, you'll have to find a k-member with bolt-on spring perches.

And, what do you mean by "mount ups" in reference to the 5.0 and 2.3? If you're talking about motor mounts, no. If you're wanting to know if they'll both bolt to a k-member in the same place, yes.
