I got a set from ebay for 100 bucks plus free shipping, and they are for a 78 magnum, and are black zinc coated so no rust issues later.
 
for just a normal cruiser,prob not worth the money.for a car that sees any track time,or is even driven hard,they greatly reduce the braking distance.a good saftey item i like to put on most of my cars.they will improve any brake system they are installed on.

only time they make a real difference is when you get your brakes hot.if you drive aggressive for any period of time,they are worth the money.if you drive easy all the time,dont bother.remember,we love to spend thousands of $$$ on our motors to go fast,but often times forget to spend $100 to $200 more to make our cars stop well.:grin:
 
Baer drilled and slotted rotors.. I would purchase again :headbang:

I don't see much need for them unless you're autcrossin or somethin like that. Regardless of how much you drive, you'll never know the difference unless you're taxing your present brakes to their limit NOW. JMHO.
 
Has anyone noticed them being noisy when getting on them hard? When driving normally they are quite and work great. They have a buzzing noise when I get on them harder.

Well sure. That's the slots displacing air much like a airplane prop.
 
You need to be a dealer of somekind to buy from mbm brakes. Ebay item number
Item number: 150674905866
Item number: 150673326347

Check brake rotors for a 1978 dodge magnum, and these are the 11.75 inch rotors. There is a bunch of rotors listed and I posted just 2 of the many.

I called MBM and they sold to me ???? not sure the 11.75 inch rotor will work with my factory caliper ?
 
11.75" Nice sized rotor... Does that require the 15" wheel for clearance with the caliper?
...Been looking to upgrade the Coronet....

Stu, I have the cross drilled/slotted on the front of my bird, I'd let you know, but as of now the car has the Fred Flintstone braking system
 
Moparstuart, everytime I see them advertise, it says contact your local dealer....so kudo's to you for getting them to sell to ya. With the 11.75 rotor, you need the caliper adapters for that bigger rotor and they came in the pin & slider style, so it depends on what caliper you have...pin or slider. Also, the spindle must be 73 and up if I'm not mistaken.

Propwash, a 15 inch wheel is a must with the 11.75 rotor. I just finished my conversion to the larger rotor, caliper adapter and semi metallic pads and they are awesome. Dont get me wrong, the 10.87 rotors are good, but if ya got the "go" you damn well better have the "whoa"!! This conversion use's all the same brgs., seals, and the dust cap. Just a note that is worth mentioning that I haven't seen, read, or brought up is the fact that you need to use a 2 inch grade 8 bolt for the caliper adapters cuase they are thicker at the mounting hole, also use a lock washer.

So bottom line, find the appropriate adapter for your style caliper and get to swapping.
 
for me i just wanted a bolt on rotor for my current spindle and caliper set up , didnt really wanna go changing good parts out and wanted to use the stock stuff I have which is only 4 years old anyway . Budget minded change over is what i was going for .
 
hemi, What front brake lines are you using? The disc conversion kit I installed on my '67 Coronet went on nicely but the brake line gets tighter than a banjo string when the wheels are turned against the stop. Tech support said I might have luck with a '69 Camero line. The '73 Dart line is what's on the car now.
Thanks :icon_confused:
 
How do you have your calipers mounted, front or rear? If they are front mounted, I could see them being too short. Rear mounted will give ya the slack you need. I dont know what part number for the lines as I got some that are stainless braided which serves 2 purposes, 1 they dont swell like the rubber lines and 2 they offer better abrasian resistence not to mention they look cool.
