There is a lot to do when modifying our Hellcats for the "Need for Speed"
I usually recommend that you enjoy your Redeye without any mods. If you go to the Track of course you will need Drag radials and a Diff brace
https://highhorseperformance.com/do...t-challenger-and-2018-demon/safety-equipment/ It's the Best Peace of mind mod you can install on your car for the track.
Running your car stock and getting use to it will also benefit you and your knowledge but also if there are any problems, then you should still have your warranty.
If you are going to Daily drive your RE a lot, I would check out having a Dual Tune and decide on the fuel you would want to use and how it works, meaning the maintenance to use it.
Do you have any idea yet when your RE will be available to you.
Congrats!
Linda
