Any plans for it? Different pulleys, wide body, ecu flash?

I didn't spend much time looking at them though because the lug pattern is different, plus the OE Hellcat rotors sit too far inboard for a 3S.

Also the calipers wouldn't work because you can't "flip" them, since the crossover is built in.

my cost on the OE gtr rotors is 548. 1012 for the hellkitty parts.

Yeah not sure if the hats are interchangeable or not, but I’d assume they are. My guess is the actual disk itself is the same.

I should clarify, my guess is the hub to disk mounting is the same. GTR rotors are drilled from the factory, Hellcat's are not.

Also, we need some more details

I was right. 12+ GTR and Hellcat rotors are the same dimensions, only the hats are different.

Steve, so is your cost for earlier GTRs (they had 380mm rotors), or 2012+?

i guessed at a year and picked 2013. catalog says 2011-21, 23-24

Yeah as long as they're 390mm, the rotor rings are the same for GTR and Hellcats. Only the aluminum hat is different.

So you're saying i should buy GTR's when then need replacing?

Not a lot planned right now. I mostly want to make it more theft proof. You can defeaf the key fobs pretty easy and also quickly pull it out of gear if you want to tow it instead. The second item would be a quick fix with some parts, but not sure yet on the key fobs. Probably have to hide an air tag in it somewhere as well.

No desire for more HP as it more than I am even used to. Its already a widebody.

Right after the test drive.

From the info I found yes. You'd have to move your hats over to the rings. I think you can get 1 piece rotors too for a Hellcat from what I saw online too, which would likely be cheaper than either option.

Yea, i wouldn't mind recycling the hats if it saved hundreds off the price. I didn't know they had 1 piece rotors as well. I wonder what you sacrifice going that route?

Weight mostly... I saw aftermarket ones, they weren't Mopar ones.

That's awesome. Congrats!

A lot of times the hardware to hold the rotors to the hat is one time use. But it should still save some money.

Well that takes away all the fun.

Thanks for sharing that. I like the price and that its a simple solution, but how well does it stack up compared to OEM Brembo.

Also, i hardly go through regular rotors. What makes you all think ill need to with the Brembos?

i have a pulley and crank pinning kit for that thing....

Dare i ask why?
