I believe they're all the same size. I went with Power Stop on my Brembos and went through two sets because they were horribly out of spec. Just a heads up.

When you say out of spec....did they vibrate at highway speed braking?

I've been searching on here and googling..but I can't find a definitive answer. Do all R/T's and Hemi DD's have 350mm rotors?

no matter the configuration, if your rear rotors are vented you have 350mm rotors.

I second that what Tom says, if the rear are vented the fronts are 350 mm and the rears are 330 mm. Also all the R/T and all the Hemi's have the 350 mm fronts

I have been running the power stop kit and am very pleased with them. If you search my posts I have a detailed write up on them. I have a track car that I run expensive brakes on for the last 8 years, I am no expert but I know what that has worked for me anyways. The power stops have a VERY specific brake bedding cycle as do most performance brakes. Not saying drewby12 results stem from that, but not following the bedding procedures can definitely result in similar issues. I have seen guys warp very expensive rotors at the track from heat soak and improper bedding procedures. After I run through the bedding heat cycle on my car I will roll it forward in neutral after 5 minutes, and continue to do so until I can place my hand on the hat of the rotor without getting burnt. Whatever brakes you choose, if they have a bedding procedure, follow it to the "T" for best results and longevity.

I'm not positive, but I think the rears are all 330mm.. the only question is whether they are vented or not..

edit: on the GCs, only the SRT gets a 350mm rear rotor.. so not likely there is a 350mm rear on a Durango..

I need rotors for my 2013 DD Crew w Hemi as well. Does the sizing hold true for Crew or only the R/T? I do have vented in the rear. Based on the above would I have "fronts are 350 mm and the rears are 330 mm"?
Thanks!

I upgraded my rotors and pads (see sig for details) and am very happy. Also don't forget to upgrade your brake fluid, I put in Motbul 600 so I'd have the highest boiling point possible. (I live in Phoenix and its gets warm here.) :)

Even if you have the best pads/rotors, if your brake fluid boils, none of that matters. :(

Good Point just make sure that you use a compatible fluid for the system

I am confused by this statement, because I have a 2014 R/T and the front and rear rotors are solid (not vented). My was a very early 14 model, was that something the may have changed? I was looking up specs and it states that all RTs should have vented fronts. I was looking to upgrade my brakes and rotors, and it seems odd. Am I misreading these posts? FY14 R/T no tow.

Thanks

You're thinking slotted I believe. The front and rears of all r/t's are vented, as in they have internal veins that are on the perimeter of the rotor not slots that go though them horizontally.

Anyway yours are 350 front 330mm rear vented rotors.. Most guides when purchasing will ask if your rears are vented or solid. Check vented and you're good

Sorry to bring up an older thread but I have been searching for this!

We have a 2011 Crew 3.6 AWD and I can't find anything about having HD brakes or anything that says what size is (350 or 330mm) on the build sheet. Vented front, solid rear. Fronts are feeling warped and since I just put new rubber on it the brakes are next.

Thanks!
