Seems like no matter what I try, when I get into higher class cars, the rear end of rwd cars always want to slip out unless I’m babying the throttle. Is there a way to fix this via tuning or do I need to not slam on the gas out of corners?
Use traction control.
Other than that, choice of car is critical, as well as how you build and tune it.
TCS
Good throttle control
It’s rare to be 100% throttle on a loose car out of tight turns
Tuning:
Lower accel diff a bit, but sometime tune for more grip softer suspensions, negative toe on rear helps the rear follow the front input a bit.
But throttle control and TCS should help out quite a bit
Does TCS make you a lot slower?
Non-TCS drivers with good throttle control will have an advantage over you, but it’s not monumental.
Depends on the car, build and driving style but generally: slower up to S/800, sort of even in R/900 and faster after that.
It’s not “essential” unless you’re racing at X/999 however, as the Lotus E23 is significantly faster with TCS on.

I wouldn’t have it on below R (Maybe some S class cars too, that have tons of power) but I run R class including the 70 F1’s with out TCS normally. At P class I can usually handle the car fairly good with out it… the F1, pretty much default to it on.
TCS seems to me in FM6 to be a bit more intrusive. but this could be me getting better with throttle control and using power to rotate the car, so when it kicks in and doesn’t allow me to do what I want to do instinctively, i notice it. In my mind it should be a tool, to be used as conditions warrant. So if throttle control is an issue, I think throttle control should be worked on, TCS for me is consistency - I practice with out it - as my errors in throttle control are extremely evident with no TCS on and possibly would race with it in higher classes depending how consistent I am with it off.
TCS is very helpful for higher powered accelerating cars and the FAST guys clearly see TCS as a benefit there as they are supreme at car control, and use it through out the LBs My run on Leguna with out it I felt the benefits of it off in the first half of the track but second half especially the corkscrew, I wish I had it on in Harmonic’s stock tires tune on the Jag.
There is no clear answer. What ever make you fastest - or depends on what your goal is.
Most lower class cars E through A I would default to 100% off, but there are always exceptions to the rule, in Forza.

Potentially, yes, in some cars.
Spinning out/sliding/drifting on corner exit slows you RIGHT down, though. If TCS helps you avoid these, it’s making you faster.
I use it in MODERN race cars, and some really high-powered road cars (eg Lykan Hypersport).
Most of the time a combination will do. Use tune advice from the post before. Sometimes it is enough. If not you can use TCS. But TCS is not the excuse to slam the trottle. Everytime it comes in, it slows you down. See it as a life saver if you are to eager on the trottle. Just a good tune in combination with trottle control have to do the job. TCS is an aid, not a reason to use the trottle binary, because you will be slower.
I use TCS only on the E23 lotus F1 car. TCS is too intrusive (for my tatse) on all other cars. It is the only car in the game, that I have been unable to “tune out” the tendency of the rear to break loose out of a lot of corners.
If the car is breaking loose out of corners, the first thing I do, is practice better throttle control. I prefer to do my own traction control, manually, with my right index finger. The second thing I do is look at the balance of the car. I usually turn the Diff Accel setting to the right, a little bit, until the back end starts gripping, then back off a click or two. I run my Decel diff setting at about 50% of accel.
Gearing also affects this.
I tend to run gears a bit taller than most folks; gears that are too low, or simply leaving a corner in second when you should have left in third can cause the rear to break loose. First is for starting. You should never really need it on the track. Second gear is the lowest gear you should be using, and then, only in the slowest of corners. (That said, there are one or two corners, that, in certain cars, I do go down to first.) Running gears that are too tall can have the opposite affect, and cause the front end to lose traction and push off into the weeds.
The last thing I do to correct a loosey goosey rear end is to adjust the suspension. I will back the rear ARB (to the left) a bit, until I get the behavior I want. I may also adjust damping/rebound, and spring weight, moving each to the left a bit. ARB’s, and suspension settings affect the blanace of the cars handling. Get too far gone on any of them, and it can have a negative affect on the car’s handling. I do tend to run ARB’s, and suspensions tighter than most folks.
You got me thinking! What’s ARB? I’ve never heard that when it comes to tuning talk.
So many options to tune out that wheel spin.
The first place to start is the differential: reduce the acceleration setting down in small increments until you either tune it out or have reached about 5. I wouldn’t go any lower, and once you make a few different adjustments, you might be able to increase it some to prevent chassis twisting and unusual handling characteristics m.
Next: I would adjust the suspension, ride height, front and rear springs, rebound dampening and bump dampening. These all effective another as well as several more aspects of the cars handling setup. But, I always drop the ride height all the way, unless It gets low enough where it could bottom out. Bottoming out will slow you down quickly, and break things. Most cars are safe and effective at their lowest setting as long as your springs and dampening are not too soft. But, to tune out wheel spin, softening the suspension and dampening can really help.
After that, I would adjust the rear anti roll bar down in small increments and see if I could get it tamed.
The last thing would be more rear aero, but I always prefer that as a very last resort. I have raised the rear of the car an inch or two and got it under control on some cars. On tracks with a lot of elevation changes, I have actually increased the front ride height by an inch or two. It really just depends on the car.
Take it into Test drive. Put all the settings at half way then drive and try to ascertain what the is doing and what you can adjust to fix it. Read the notes and you will quickly get a feel for what happens when you change things. So make small changes and drive it enough to really get a feel, before changing anything.
When you do begin making changes, make them small and only adjust one thing at a time. Pay attention to how the car reacts to your change and then move on when you are comfortable. I usually do a rough tune, and then go back through everything twice more (for tweaks). To fine tune each area (fine tune) = small adjustments.
Though it hasn’t been mentioned yet I’m sure you’ve already done this, but make sure your tires are good.
Use the best compound you can and make them wider with bigger rims (especially the rear). If the tires start to deform too much (as will happen under cornering forces), they will lose grip. Bigger rims make stiffer tires, and obviously the wider the tire, the more contact you have with the road.
Everyone here has just given you band aids instead of addressing the actual problem. It’s your throttle control. Neither peddle is an on/off switch. You should never quickly give full throttle or quickly release the throttle. Both cause weight balancing issues and unsettles the car. Same applies to the brakes.
You can still quickly use both peddles but you need to ease the accelerator to 100% then ease off. Sure usung TCS may help, so would tuning out the “problem”…maybe, but the main issue is your input. Once the car has set at mid corner, ease the throttle to full acceleration during the corner exit.
PS ARB is anti-roll bar.
PPS go to YouTube and watch skip barber’s going faster. The fastest, simplest and proper way to get better is to understand racecraft and WHY you do the things you are suppose to do.
Be less eager on the throttle. TCS slows you down, and is less rewarding in-game.
