I have already converted my 65 Sport Fury to front disc, is it worth the extra money/effort to go with four wheel disc brakes?

No, but then I no idea what your goals or needs are.

If you are into performance driving and make frequent hard stops, it might be worth it, but only if you've already upgraded to wider tires and wheels, do that first. For a regular driver, 4 wheel discs isn't necessary.

My Dart still has manual 4 wheel drums and it is daily driven 60 miles round trip, never had any issues getting it stopped from 70 when I needed to.

No, (and I feel that a parking brake is much more important, and many times deleted when going to rear discs) just my .02

I added rear discs from Dr. Diff. I had one hard panic stop on a back road when a harvester suddenly appeared coming the other way taking its half out of the middle. I have no proof, but my gut feeling is that the extra braking power saved me that day. But, 99 plus percent of the time, they wouldn't be necessary. However, I feel mine paid for themselves that day.

I was on my way to a Mopar show,and a friend of mine was following me to the show in his 71 Charger R/T. Some dope pulled right out in front of me and I had to lock up my brakes. I heard my friend lock up his brakes,and looked in my side mirror hoping he wouldn't hit me. Instead of him hitting me,his car was completely sideways in the road. After that incident he installed a rear disc brake kit from SSBC,and the car stopped straight and in a lot shorter distance than it did before.

4 wheel disc brakes are unnecessary for a basic daily driver. Both of the above examples are not the normal brake stops. Decide whether or not it will ever happen to you. The second episode sounds like his buddy was following to close.

If you want to upgrade, get bigger front disc,
They do 75% or more of the braking

I'm fixin to find out. Agreed, may not be needed in most non racing apps (& maybe for most of them) but I have the stuff & want to experiment

I'm sure most of the responses here are from snail paced lounge chair car cruisers who still have 10" manual 4 wheel drum brakes, that's ok, they're fine if all you have is a leaning tower of power (/6) under the hood and only go down to the corner for a gallon of milk occasionally...

But if you have any serious power under the hood, like to street race, drive aggressively, take it to the track, then 4 wheel discs are necessary in IMHO, a well set up 4 wheel disc will pull the car down fast and straight and level, and yes you can still retain a "parking" brake

personally I prefer power assisted 4 wheel discs, decades ago I was in the same camp, "ahhh you don't need 4 wheel discs", once you start building vintage vehicles with them, you'll never want a drum brake vehicle ever again, just like an OD equipped vehicle, once you've gone this route you'll never want a 1:1 final drive ever again...but Mopar guys are always last to the school of upgrades

I have been drag racing for the last 50 years and yes front disc brakes are a great thing but unless you are running a 10 second car or are over driving your car or road tracking you don't need 4 wheel discs. Road track cars do need 4 wheel but they are a whole different critter than the average go faster.

I have a 65 300 Vert. Which kit did you use?

In a really fast car, absolutely needed. The rate of acceleration is such, you need to be able to stop as quick. Agree on the other comments. Most cars are just fine with front discs.

Yep, as long as the drums are set-up and operating properly...
No problem.

Simple test. Can you lock up the rear tires or at least make the tires squeal in good conditions in a panic stop situation? If you can, no performance advantage to rear discs for a daily driver type car IMHO.

This is assuming your disc/drum setup is properly maintained and balanced.

Big C Body with 4 wheel drum brakes, Drove fine stopped fine

But I did upgrade to front disc, because on the highway (NJ Turnpike) bumper bumper traffic it would not stop fast enough.

But if I only stayed in CT with the car I would have never upgraded

Front disc/rear drum on a warm street driver works. I ran that for a while on my Challenger... until I burnt up the rear drums hot lapping on a road course.

Much better with discs all around now. Balanced stopping and I have not burned the brakes up.

On a mostly street driven car, the advantage of 4 wheel discs could be maintenance. Selection of lining materials for drums is getting thin. Quality of hardware is getting thin. Quality of drums themselves seems variable. Expertise is getting thin.

Rear discs based on a later model setup of some type should be a lot easier to service. The 4 wheel disc setup on my Challenger is Cobra based and serviceable with local AP store parts if needed.

I converted to 4-wheel disc last summer and I love the way the car comes to a smooth complete stop from 100 plus with very little pedal effort. I lean on my car pretty hard and it's nice to know it will stop as fast as it will go
I have 11" stock type discs on the front and Wilwood Dynalights on the rear and manual master from Strange.

It makes no sense to drive around with inferior 50 year old drum brakes,when there are affordable kits to convert these cars to four wheel discs. I have bought 4 kits so far and I plan on converting them all to 4 wheel discs.

Good to hear, I will do mine when the time comes. New territory but I will reduce the tapered bearing end play to zero & weld on some homemade brackets (8&3/4), not sure what calipers but likely 73-75 A body (2.60") in the rear and 76 (2.75) in the front (setup stock).
