Actually i have everything stock right now,but i have been gathering everything to do at once. The coilovers,95GT spindles and brakes,Camber caster plates and MM conversion braided lines.Just doing fronts for now ,and i have read where the 86 k-member and arms cause problems?Thanks
86 GT,ALL STOCK
The '86 K-member is 1/2" narrower per side than the '87-'93 V8 K-member. The narrower K-member does make it hard to get an acceptable amount of negative camber on the front suspension using the Fox A-arms.
Since you are using QA1 struts you are obviously NOT building a road race handling machine. With that usage in mind the C-C plates should allow you to get an acceptable camber setting. If you need a little more negative camber than what the C-C plates allow you can slightly open up the upper strut to spindle mounting hole.
The other way to fix the camber issue is to use SN95 A-arms or swap to an '87-'93 V8 K-member.

Well the QA1 s are offered for free but,i am not dead set on using them.Do they suck for handling?Its more street car than anything else.I just hope that if i use them with the cc plates i will be okay,i dont want to do the k member or arms right now only because of cost especially when i am fixing up the house and cost are already going over budget with that.lolThanks again Vince.

IMO from what i have seen and heard QA1 Is not a high quality part (s) and not made to take the abuse of racing or hard street driving. (nor are the granatelli's i bought) but at the cost of FREE, they are worth atleast getting your feet wet with coilovers.
You may not like the handling or stance they give which makes it a cheap investment to figure out if that is what u want for your car or not.
Upgrading to a griggs or MM coilover setup can always be purchased in the future as an upgrade.
I dont plan to keep the Granatelli setup on my car for ever but for what i paid and my budget at the time they are perect till i can upgrade to a better more punishable setup LOL

But Have way too much 4I stuff Collecting Dust.
the mustangman said it well. For the price, use the QA1's. You can always upgrade (spend money) later.
You are welcome for any help that I can give.

Today, I just read in my copy of the Mustang Performance Handbook 2 by William R. Mathis the '87-'88 V8 Thunderbirds have A-rms which are 3/4" longer from control arm bushing center line to ball joint than the '79-'93 Fox control arms.
This may be the ticket for those with the narrower crossmembers.
Another interesting tidbit in the book is the police/taxi Fairmont front and rear control arms have stiffer bushing and thicker metal than the regular Fox offering. Of course those cars are rarer than hen's teeth but I wonder if the police/taxi '84/'85 LTDs use the same parts as the police/taxi Fairmonts...

I remember reading the series of articles done on Mathis' "Slot Car." He wanted to change the geometery of the k-member and add some much need front track width for better front grip. But he wanted his mods to be pretty much undetectible from a visual tech inspection perspective. Hence the effort he put into making the k-member pick-up point and rear lower control arm relocation mods appear unmodded factory original. The use of the t-bird a-arms was for the same reason - appeared to be fox with the correct ball-joints and all. I don't recall why he went public with the article and eventually the Performance Hand Books, but probably someone protested and the inspectors measured the critical dimensions - jig was up.
Just curious but why would the '99 GT/V6 brakes use a 1" MC and the '94-V6/GT use a larger 1-1/16" bore MC? The '94-'98 V6/GT use the single piston calipers up front and the '99-'04 GT/V6 have the dual piston PBR calipers.
Im curious because I also am considering swapping to the 99-04 PBR GT/V6 calipers but want to have a nice pedal feel. I have a complete '94 V6 parts car and it has a MC/Booster/PV on it, as well as all the needed brake parts, but planned to upgrade the stock single piston calipers to the newer dual piston PBRs.
Is the single piston 94-98 caliper larger than the dual-piston 99-04 caliper, thus requiring the 1 1/16" MC versus the 1" MC?
Thanks

'85 Mustang GT with 4.6 conversion and complete drivetrain/brakes/suspension/wiring from a '98 GT
'86 LX Coupe..maybe a 4.6 swap....
The '94-'98 V6/GT cars have 66mm single piston front calipers. The area of these calipers is 3419.46 mm^2 each.
The '99-'04 V6/GT cars have twin 44.5mm piston front calipers. The area of these carlipers is 3108.99 mm^2 each.
The rear calipers were the same from '94-'04 (single piston 38mm).
As you can see, the twin piston calipers actually have less area. That is why they require a smaller MC.

I've read through the posts and have a question I couldn't find the answer for... My son (he's 13) and I are building his car, an '84 GT Turbo. We're going to swap it to 5-lug and since he's paying for it all (well, as much as he can any way, dad is picking up the rest of the tab, but I want him to understand the value of a dollar and building something himself with his own money) we're doing it on a budget, trying to spend the money in right places a little at a time.
Any way my question is this about the 5-lug conversion. I've got 94-95 spindles and front brakes (non-Cobra) and for now we plan on just swapping in ranger 5-lug rear drums. What master cylinder/brake booster have any of you used if doing the same swap. Most of the thread, as far as I can tell, has to deal with a conversion to disks all the way around or using the MKVII/SVO front rotors/brakes. I also have a set of 96-up front spindles/brakes/calipers. I know the spindles won't work but what about the calipers? Any help would be great, thanks.

I went with drums on the rear and licoln rotors in the front. I am using the stock 83 5.0 booster and master cyl and it works perfectly. You only have to change it if you go with discs in the back or get a better proportioning valve.

The '94-'98 GT/V6 front brakes are all the same.
It depends on which front brakes you end up going with. I would recommend at the very least switching to the '99-'04 V6/GT front brakes.
The Fox brakes have 60mm single piston front calipers; the '94-'98 V6/GT brakes have 66mm single piston front calipers; and the '99-'04 V6/GT brakes have twin 44mm caliper pistons. The 44mm twin piston calipers actually have a closer area to the Fox brakes than the large 66mm single piston calipers.
If you go with the '99-'04 V6/GT front brakes then I would try the stock Fox MC and booster first. If the pedal is too soft for your liking at that point then you should switch to a 1" MC. With the '96 brakes I can almost guarantee that the pedal will be too soft so I would recommend starting with the 1" MC.

Vince, I'm fairly sure that the '94-'98 V6/GT cars use a 60mm piston, same as the '78-'93 cars. 2.359" is a little under 60mm.Originally Posted by 85GTVince
If anything the twin 44mm pistons will tally a slightly higher area than the single 60mm. But not much different.*just doing the math off the top of my head*
I am 100% sure that the '94-'98 V6/GT cars used single 66mm pistons in the front calipers. Check it out on RockAuto.com or Autozone.com if you want a 2nd and 3rd opinion.
Just to clarify, the '99-'04 twin 44mm piston calipers have less area than the single 66mm piston calipers. That is why I said that hey would be a better match to the stock MC.

I am just itching to go to 5 bolt on my old 85 but can't decide on the correct version

'94-'98 V6/GTOriginally Posted by RA
The bores are different but they use the same size 60mm piston. Raybestos PN DPS85035. That is what moves anyway, the piston, not the bore. I have '79 V8 and '95 GT calipers kicking around here somewhere, just have to locate them. My crap shot theory with why Ford did this was probably the larger bore allowed for better service life out of the calipers. It simply could be that the smaller bore would seize easier than the larger bore. And with better brake pad materials coming onto the market, albeit pistons were seizing in their tight bores from heat.Originally Posted by RA
It was probably cheaper for Ford to maintain the same steel piston but just up the bore. The caliper was going to be a different design anyway.
