R/T rotors for v6?

Have a v6 rallye, I saw that the r/t's have the bigger 350mm rotors vs 330, pads and I'm assuming calipers? Are the mounting points the same? I'm assuming so since the srt's will fit.

Has anyone swapped them on. The SRT's would be the ultimate goal but have to also grab rims and I'm not ready to shell all that out just yet.

The loaded calipers and a new rotor are pretty cheap comparatively to the srt set and would be a good mid range upgrade.

I'd love to get brembos, but I'm not getting rims till summer and the upgraded brakes would be around the following spring. The braking performance isn't bad now honestly, I don't tow often nor do I drive it super hard so it's more of a peace of mind things, and I can always do them independently fronts or rears first without having to swap out rims

While on the topic though, do the srt gc'/ Durango r/t's have bigger master cylinders than the v6 and non rt models?

You will need wheels with the Brembos, but the 350 mm front and calipers from a R/T will bolt on.

I got a whole set of RT discs, calipers, and pads for sale - off a 2015 RT - I did the Brembo upgrade and with wheels and tires it set me back 4500 .
the brake parts all have about 3200 miles on them, nearly new as we have had the car 4 months, and put the brembos on after the 3rd month, PM Me if interested, they are for sale on ebay, I will give you a good deal.

So after doing some parts checking and rechecking I found that at least the front calipers and pads are the same for the r/t's and v6's. Rock auto, Mopar and Mopar overstock all list the same pads and caliper the only difference is the caliper mounting bracket (spaced differently to fit the larger rotors) and of course the rotors themselves.

Going to check with my parts guy Monday at the dealership. If so I can buy the larger Brackets for 31 each. And just oder a brake kit. I'll verify Monday for both front and rear. If so this cheap (realitively when replacing brakes anyway) just got a lot cheaper.

If anyone Has some differing input let me know... I think the "heavy-duty" part of the equation is just the larger/thicker rotors in the front and venting and larger in the rear to disapate heat better not necessarily stop any better since there's really no more surface contact.

Again I could be wrong but they all list the same pads for all models and same calipers just different mounting brackets and rotors

the bigger (and rear vented) rotors will stop better after the first hard stop or a long braking run - because the linings will be cooler..

with the pads being further from the axis of the rotor they might be able to exert more stopping torque as well, but I'm not a mechanical engineer..

I was thinking the same thing. Per their heavy-duty description they should be more consistent because of heat disapation and resist fading in situations like towing, long down hill runs etc.

Looking at braking tests the r/t's and v6's all stop in the 120ft range from 60. Weights do vary but most are citidale awd v6's, and pretty bare bones r/t's all within a 100lbs of each other

I finally did by call centric. The calipers are similar but the spacing on the mounting bolts is different by just enough that it won't fit..

So you'll need the calipers too for both front and rear. Which are about 40 each (remanufactured) before a core charge. Along with the rotors, pads.

If you're towing a lot or want a mid range up grade it could all be had for about 220 on top of a normal rotor and pad replacement. Mine are about ready for it so I'm still debating if it's worth it.
