11 3/4 " brake rotors ? - 10/20/21 07:14 AM

hi
where can i get replacement rotors that are a little lighter in weight than a stock one as the ones i have are about 25 bs each . 11 3/4"

just looking to up grade the brakes and maybe loose a few lbs. ?

got some new ones 10 1/2/ in and they weighed same as 11 3/4" ones ???? 3750 lb



thank you !

Dr Diff sells them, you might give him a call and ask if he'll weigh one for you. You might have someone with a lathe cut them down a bit too but it would seem a bunch of work for little gain. twocents

if all out race car is not in your future, cutting stock rotors is a waste of time and money in my opinion.
if better stopping power is your goal, it would be better money spent if one perused the different pad material available, then select what suits your driving style best.
just my opinion, your mileage will vary.

Closest your going to find is a set of drilled and slotted ones though not sure the weight savings is much. RockAuto has them. Weight not listed though, 79 Cordoba is the application.

Great info here. Thanks!

Also, Firm Feel sells really good pads for Mopars. I run them on both my Mopars with the 11 3/4" rotors.

A ‘76 Fury has the 11.75 rotors too. Used to be a good swap, maybe other this are better now? The adapters are hard to find. I thought Andy f was making them though.

I have 11 3/4 rotors. Got the brackets from DrDiff. No difference in braking. Waste of time and money. Will go back to the 10 1/2 needed.

yea ;

i have a cuda power brake and a valiant non power disc and i like the pedal feel on both better than the 11 3/4 belvedere so far .

cuda 3650 lb val 3250 lb both stop good .

maybe i need to change mc from 15/16 ? works like power brake just a little more pedal movement than i like .

There has to be more to it. I made the exact same swap on my porker of a car and it made a fairly noticeable improvement.
