HELP! Tuning a Hellcat for Cornering

Hi there. I am very new to the world of tuning. So I’m slowly but surely learning how to do so. However, I’ve got a Challenger Hellcat that I would like to tune to be able to corner well/be stable at high speeds. I am not looking for a drag/drift tune. Seems any tune I’m able to find has been for that. The Hellcat isn’t fully upgraded, however. I’m unsure whether it matters, but I do have the LB Works body kit on it. Below is the current list of parts on it.

Vehicle Class: S2 (PI: 917)
Conversions/Swaps
None
Parts List
Engine:
Stock Valves, Sport engine block, stock pistons, Positive displacement supercharger, stock intercooler. Everything else is fully upgraded.
Platform And Handling:
Race front & rear anti-roll bars, stock/no chassis reinforcement. Everything else is fully upgraded.
Drivetrain:
Everything is fully upgraded under this field.
Tires And Rims:
Horizon Race tire compound, front 325/325R20; rear 355/30R20, stock rim size f/r.

The only “conversion” on it is the LB Works wide body kit.

*One thing I have noticed is that the rear end ‘wiggles’ a bit at high speeds. Surely this can be tuned out. Additionally, the tire-happy nature of this car doesn’t bother me a great deal, but with any luck, I would like to eliminate a little bit of it. Apologies if I seem quite ‘picky’ lol.

I think I have an S1 class racing tune for the hellcat. I’ll give it a look over and see if it’s any good.

Edit; I do have an s1 version of the hellcat with the original engine and it is a rally tune, so it’s awd swapped. It’s so heavy that there is little other use for it. I have the tune shared as “2 tons of fun”. I’ll see what I can do about a rwd tarmac version for you… no promises it will be any good tho.

edit 2; I now have a RWD RACE tune up in my storefront now. It did well as a RWD loosing almost 500Lbs while gaining 100+HP, 90torque, 2 more gears and 6MPH top speed. This car might actually do better times as RWD on longer circuits and definitely on goliath.
Differences from your current build; I dropped down to S1 class but increased power by using a stock front wheel width(with wide body kit), stock brakes, no stiffening, no oil, no flywheel, street exhaust and all other engine upgrades maxed, yes even the intercooler. In cases where the car already has an intercooler, upgrading the intercooler is advisable since the negative handling effect is already there and can’t be removed.

Awesome. Thank you. Yes, as I said, the “Hell-yeah” (as I’ve affectionately nicknamed it) doesn’t need too much as far as upgrades go. To further that, my sole purpose for it is purely to cruise with. The torque is such a pain, though haha. Might purchase the Charger Hellcat as well. Not too sure yet. I mainly just want to get rid of the wiggle in the rear end. Thank you very much, though.

Also, I don’t believe you included the name of your tune. What is it called? lol

It’s called RWD RACE.
Sorry for the late reply, I was on vacation.
