Is there any 4 slug powered front disc conversion kits out there for a 6 cylinder mustang? I would like to keep the original rims on it from the factory. The only one I have seen makes us use a bigger wheel and rim size.

Thanks!

What would it cost to convert to a 5 lug?
Thousands, by the time you are done.

Do you need to go part hunting or is there a conversion kit out there? Also why are the ones on Scarebird.com so cheap?
Because you need the brackets they provide ($95), Then you go shopping. IIRC, you need to get Ranger rotors, Cavalier calipers, and Cadillac hoses. If you can find someone who'll turn the hubs, you can do the whole deal for about $200, if you can turn the wrenches yourself. You won't even need a wheel alignment, because the spindles are undisturbed.

5 lug?

Don't know if it's thousands, but remember 1 thing- a 6 cyl mustang uses 1960 Falcon brakes. Didn't stop a Falcon too well so the larger brakes are a major safety upgrade. There are a lot of places where you can get the front end parts fairly reasonably. Check with Chris @ Vamustang.

I change mine all to V8 suspension and brakes. It did not cost thousands maybe 900 to do front and rear. Look at CJ PONY PARTS they have a few four lug disc kits to choose from.

couldn't I just buy a Front Disc Brake conversion Kit. 4 lug to 5 lug Disc? Then just buy a different rear end?

Because I plan on getting different wheels and maybe doing a V8 conversion sometime next year.

yes....I don't know what your budget really is, what your tool situation is, school, work, where you are going to work on the car, whos going to help you, if you need to drive it everyday, etc etc is, but... being young and a novice you may want to just drive and enjoy what you have for a while. There are lots of upgrades you can do with out breaking the bank or going beyond your skill levels, Maybe a dual mastercyl, turn the drums, quality brakes-o/h kits, l.e.d. lights, upgrade the headlamps to halagen and wiring, do the frt shoulder 3 point seat belt swap, a 3rd brake lite, a back panel gas tank shield, a nice stereo, and alarm, go perform all maintenance by a checklist -ujoints, tie rods,springs,exhaust etc etc ???,maybe plan to properly paint and freshen up the engine and the engine bay. Hows the headliner, carpet, interior in general? My point is that you can "work" on your classic and be proud of your accomplishments without going overboard at this stage of the game.That oughta keep you busy and out of trouble for the next year or so. without breaking the bank. Did I miss more pictures of this car? ok, good luck and happy motoring!!!!

parts

I just stopped to visit Stan @ Mustang Collection in Miami. If you need these parts, he has them quite reasonable and is trying to down-size his parts as much as possible for good prices. 305-264-4130

So its better to keep this car and take care of it for a few years then sell it if I want to upgrade to a V-8.

You're onto the right idea... For now, just do what is necessary to make her dependable and safe and enjoy driving a classic Mustang. While I'm really happy with my Chockostang disc brake conversion, the car drove fine with its original drum setup (in my case, I had already converted to an 8" rear, so I wanted to go to 5 lugs all the way around).

On my own six, I've converted pretty much everything but the engine to V8 parts- knowing full well that I'm digging into a hole- but I'm at the stage where I have disposable income to indulge a "hobby." When I owned a '65 in my younger years, I was happy just to get her running well.

Having just returned from the Mecum Auto Auction in Dallas, it is painfully obvious that the "smart" path is to get the car drive-able and enjoy it. I spoke with a kid (well, 26 years old is a kid to me) who had sunk $40k+ into a 2004 Mustang... the car only hit $10k on the block! No doubt about it, the car was built really nicely (and tastefully too)- but...

Best wishes however you decide to proceed!

Are you're wheels stock 13" or 14" four lug wheels I have devised a kit that you pull off the drum hardware easy. Then clean off the spindle and check for excessive wear by the bearing does happen. If fine then what next is my cad designed brackets that bolt to stock four lug spindles. Then slip the new hub on with same year bearings. Then put on rotor and caliper and your almost done. Next is proportioning valve hooked to rear line this help to prevent drag on rear brakes. Then after this is done next I would suggest if you want manual brakes still I would suggest a 67 mustang manual master cylinder. If you want power I would suggest looking into mustangsteve.com he makes a power disc brake conversion kit with booster and revised Pedel pin. You have to change the Pedel pin placement because the power brakes use different amount of force then manual. If you want five lug I also have a kit to convert over to five lugs using original spindles if not going to high horse power v8 which you'd want bigger spindles then. These are some options. If you do however go scarebird route be aware that you will have to change to 14" wheels if yours uses 14" you need the bigger center cap version which are kinda a pain to find.

The 14" 1964-5 wheelcover is reproduced.

The standard wheel in 1966 was 14", even on the T code cars, so he is unlikely to have 13" wheels.

Even so, the 66 wheelcover is reproduced, too.

My first Mustang was a 66 Sprint, so I'm partial to the wire wheelcover-

I'm pretty sure my wheels are 14inch. I was reading on some other websites and what not and I have found that this is one of the best kits for the disc conversion.

What do you guys think?

I just recently upgraded with this kit and am very happy with how things turned out. Big difference in stopping power! A friend of mine and fellow Mustang club member did most of the assembly work, but I was there the whole time to help. It's a straight up bolt on upgrade. The only issue I can remember was that the kit didn't come with a mounting bracket for the proportioning valve and we had to fab one. It's also a tight fit installing the bracket that holds the new MC/power assist unit to the firewall. The instructions even mention this, but everything fits, just a little tedious tightening the bolts. Also, at the suggestion of my friend, we replaced the under dash brake light switch with a stiffer 67-68 unit. I have lots of pics I can share if you decide to go with this kit.

The only problem with that kit it fits 15" wheels not 14". The other kits out there the high dollar and low dollar ie scarebird don't even fit stock 14" wheels this is due to offset issues. Also there are different versions of the 14" wheel. There is the smaller center cap version and the big center cap version. The bigger center cap version and other newer disc wheels are what scarebird and others suggest using other wise the caliper will grind on the wheels.

I'm currently running the SUM-BK 1223 kit on my 65 convertible with period 14" 4-lug wheels and it works just fine. The overview on the Summit page does seem a little confusing as it "recommends" 15" wheels, but there's no such thing as a 15" 65-66 4-lug wheel for the Mustang. Further along it states that this kit is designed for "4 lug models with automatic transmission only." If you have a manual transmission, I would call Summit before ordering to see what the mean by this. The SUM-BK1222 overview states "Designed for 4 lug, 6-cylinder models only." No mention of automatic only for this kit. These kits are definitely not for the earlier 13" wheels, however.

If there are concerns, simply call Summit. Like I said, it works well on my 6.

I agree Steve....14" tires are getting hard to come by today...but are still out there. Cooper, Hankook, and BF Goodrich still carry them...For now, ..Thank God. Of course, There is always Corky Coker at Coker Tire...Nice guy, but his tires are expensive..Like around $200 a tire....!

I actually think that there are more Tire manufacturers making 13" tires than 14" tires...The reason? Lots of imports take and use 13" tires......14" tires are basically for American made cars.

I know I'm late entering this forum but just wanted to thank you guys on the advice given here. Made my choice a little easier. Just bought the Summit Racing bk1223 kit for my 1965 Mustang (6 cylinder, 200ci, c4 tran.) Hopefully the conversion goes smoothly. Best price out there too. I have 14" stock wheels so I hope I don't hit a snag.

To answer the actual Poster's question,

Yes. There are a couple 4-lug Disc brake conversion kits available. NPD has them all. Two of them are apparently made by SSBC (Stainless St Brake Corp.)

Here they are below. Bust out your wallet though, They are not cheap, but are of high quality, and what's the price of safety?... and you can still retain and use your stock 14 inch wheels. It fits '65 Mustangs and Falcons as well.

See the weblink below:

You have overlooked the Scarebird disc conversion, which is very inexpensive, and works with the stock steel 14" wheels. That's the kit I mentioned earlier. With careful shopping, and machining your old hubs rather than buying new ones, you could do the conversion for under $250.

I did the Scarebird conversion also and my total was about $350 to include duel bowl MC conversion and replacing all wheel bearings and seals in the process. Conversion worked with stock 14 inch steel wheels also. Very happy with the results.

6 cylinder disc conversions

Schmitdy, I sent you a PM a little while ago. Check it out. I did what you are thinking of doing. I bought the Scarebird adapter plates and purchased what they recommend and everything worked with little or no problem. The only issue I had was that my original 4 lug rims rubbed the calipers. Evidently the four lug wheels are different depending on where they came from. The vent holes on the back side of the rim protruded just enough that they rubbed the caliper. I ground the calipers down as far as I felt safe doing so and when that was not enough, I took the rims off and flipped them over and took a BFH and pounded the vent holes down a bit and all was well. We have been driving the car for over three years and have had NO problems. I am now converting the 6 cylinder steering and suspension over to the V8 components. So, the old 4 lug components are for sale. if you're interested in obtaining previously installed components, in perfect working order, get back to me. I can send you the original instructions if you would like to see what's involved. The machine work to the existing hubs has already been done. The only thing you would have to buy new is the brake lines as I am keeping them for the new conversion. Thanks
