Wondering what the weight difference between the two are. Demon rotors are pretty dam light. Wondering if the $16k is worth the reduced weight that carbon offers.

10% of vehicle value?? I vote NO
Buy a Barrett 50 BMG and a bunch of ammo and that will give you more fun factor per dollar than lighter rotors:ROFLMAO::love::cool:

By itself no way would I buy them but ive done like everything I can think off to lose weight for my Trackhawk so im just wonder what the actual weight difference is.Front Cemon Rotors weigh 24 lbs. which is 7 lbs lighter than stock at 31 lbs. I assume its the same or close on the Hellcat.

I got like $250k into my Trackhawk so its more like 3% of the vehicle value lol. Whipple came off. New build under way.

You loose a significant amount of unsprung weight just with the DP rotors (made by Girodisc). The additional amount WTF ever it is will not be worth over $13k!! I use them and they are rock solid and tough. If you have a Porsche WITHOUT the dumb ceramics, you have the very same rotors!

I think my whole life is in that truck bro lol I keep adding shit and have considered going TT but im afraid ill ruin what makes it fun and thats the instant hit u get from a dig at idle and that will be gone unless I lay on a 2-step which im not doing at every light but I sure can smash it at idle lol.

I have spoken with a couple shops and im entertaining my options. Its a grudge car but I do street drive it. Wanna take to drag week or sick week next year as im retired and have no life now ha. Wanna do Texas and Fl 2k as well and be competitive on the street from a dig.

Ripatuned has some really nice new stuff out for the TH and Durango. Fancy interchiller that fits right into the factory bumper and connects to OEM lines. Ripatuned and Satera seem to be the Hellcat shops with the most experience with Turbos. Im sure there are others but they dont post much.

No one offers a bigger TB for the 3.8 yet which is frustrating but guys are making 1400 whp with the 108mm so I guess thats good enough. I might sell the 3.8 Whipple but its nearly impossible to find for sale tho so if I change my mind I doubt ill be able to locate another. Its just mocked up on the Trackhawk right now its still brand new. Need to modify hood.

My current shop only got one but maybe Dustin will get more parts to make more but they call this the Drag Pack and say they are limited so idn what to think or do.

Jeremy at Satera says his Flexfuel tune is like no other and that he has essentially hacked into the stock ECU to allow it to make the proper changes it needs to make when the ethanol sensor reacts. He says everyone else just guesses. IDN how true that is but id really like the option of running ANY fuel I want ANY time I want safely.

Ripatuned apparently does Flexfuel as well but I have not spoken with them about it yet.

From what ive discovered:

Stock Front Rotor: 31 lbs.
Stock Rear Rotor: 24 lbs. 110 lbs. of rotating mass.

Demon Performance Front Rotor: 24 lbs. (7 lb Difference vs. Stock)
Demon performance Rear Rotor: 19 lbs. (5 lb Difference vs. Stock). 86 lbs of rotating mass. 24 lbs of rotating mass reduced over stock.

Carbon Ceramic Front Rotor: 15 lbs. (16 lb Difference vs. Stock and 9 lb Difference over DP)
Carbon Ceramic Rear Rotor: 12 lbs. (14 lb Difference vs. Stock and 9 lb Difference over DP) 54 lbs of rotating mass. 56 lbs of rotating mass removed over stock

So u can clearly see the weight advantage with carbon vs. the DP rotors is greater than the weight difference between the DP rotors and stock.

Thats about 28 lbs of rotating mass..... Thats a lot. I have the DP rotors on my Trackhawk and Redeye ive done everything I can think of for weight reduction so im considering the carbons now. They seem to be woth the extra money at 28 lbs of rotating mass removed.

Thats about 150 lbs of dead weight removed. Of course its not the first thing I would do to remove weight its clearly the LAST thing ppl should do imo but considering stocks weigh TWICE as much its a good mod imo.

I just put them on my Redeye and the car clearly leaves harder from a roll now. Thats fact. Also brakes better and handles bette. Put them on Trackhawk as soon as I bought so I compare the two there. My Turbo Mustang has em as well.

Well good luck. If you get them we are looking forward to what your time slip difference will be. As we know it is exponentially more expensive with each mod, the quicker you want to go.

At that point I would put skinnies on the track hawk up front and lock it in RWD mode. Less money, same impact. I removed 32lbs per side up front switching the front runners
