5 lug conversion

[SYMach9184]

Im looking to switch from 4 lug to 5 lug on my 92 notch. What is my best option? I want a 4 wheel disc brake setup, and possibly 13" rotors upfront. I checked out the ford racing setup but it is alot of money for brakes. If that is the easiest option then I will do it but I would like to see what others did first. Also what suspension and wheels are you guys running with your conversion? Thanks Mike

I would say 94-04 A-Arms, GT Calipers and spindles up front is probably your cheapest route if you don't care what you have up front.

Run 94-95 spindles and hubs, reuse your Fox A arms with 94-95 Balljoints and get some 13" rotors and Cobra or GT calipers for the front.

Rear I suggest going with NRC's rear kit.

I would recommend keeping your Fox control arms. The 94+ front lowers widen the car quite a bit and aren't worth it.

Cheapest way is to pick up any 94+ front spindles; 94/5 are preferred.

99+ GT's got PBR 2-piston calipers, think a "baby" version of the typical PBR Cobra caliper.

That is plenty of brake on the street with the proper pad and a fresh set of rotors.

North Cobra rear axle brackets are def. the way to go as they retain the stock rear track width/Fox length axles.

You can source cheap 28spline 5-lug axles from the Ford Ranger. 5.0 Resto also has an economical kit for the rear.

Or there are several rear disc setups.

If I use the stock lower control arms all I need is the spindles and hubs from 94-95? If so do I need any master cyclinder upgrades or brake booster? Will 03-04 cobra wheels work fine with this setup?

 

[SYMach9184]

What about the stock ball joints?

 

[blownfox]

I have 94 GT spindles, 03-04 cobra calipers and rotors, and I'm using the stock master cyclinder/booster. You should only need to up grade the master cylinder if you convert the rear to disc.

I have stock ball joint but I had to shim they up. The only reason I did this is because I will be doing a K-member and will order 94 arms and ball joints.

Right just find some 94/95 spindles and hubs, (96-04 are a wider track) and i'd just buy a set of 94/95 ball joints you can shim them but I've never really liked the idea of that.....just me.

As for the MC i'd run a 93 Cobra MC and yes 03/04 wheels will work.

NRC= North Race Cars

If you are doing front and rear discs and want to go all out and do it all. I have this stock pile sitting in my garage waiting to install.
94/95 Front Spindles
New A Arms, I went with granatelli k member and A arms, bumpsteer etc
10th Cobra front calipers and rotors 13"
93 Cobra master and brake booster
proportioning valve ( not necessary )
MM stainless lines front and rear
North Race car brackets for rear
moser axles
Cobra rear 11.65" discs paint red to match 10th fronts
93 Cobra E brake lines (3 total)
17x9 OEM 10th Anniversary Wheels

I am going a little overboard I just wanted to get it all done at one time.

Would you sell the 93 Cobra MC and booster?

Here's a good article on Stangnet.com about Fox 5-lug conversion:

edit: I would change the master cylinder. I put an SVO one in, but I read above a '93 R would also do.
