These cars are supposed to have some oversteer to hold speed through the turns.  If you get the rear to stick more they quickly switch to an understeer that really slows you down.  But normal setup changes apply;  more rear wing (often only one or two ticks is sufficient), less rear bar, softer springs, or a trackbar adjustment.

Not enough information.

Rear grip...
entering a corner?
through a corner?
exiting (acceleration) a corner?

Every track, or specific tracks?

What makes you say it's rear end grip? Perhaps it's overall balance, steering ratio (sensitivity), gearing.

Gtp cars are throttle sensitive, you can't just mash it. Perhaps you're getting into the corner too fast, getting back to WOT too quick.

Loose is fast. These cars drift, they don't have the grip of a F1 car.

fortine_oo, indeed much too much steering sensitivity, changed it!! How about weight balance? In the middle? would that help?Thank you :hat-tip:

Imo, it is impossible to make a setup that will bring you high grip everywhere and, in fact, it could not be the better idea sometimes.

I think you can get more grip:

1. using more wing. However, if you use too much wing, you will get understeer at some turns and will also be slower at the straights.

2. I use to reduce the rear rebound a bit so when you use the throttle the rearend will be less wild. However, as has been said, you must use the throttle gently with these cars.

3. at high speed turns, it may help to stiff a bit the rear springs so the rearend won´t get lower and you will get more wing effect (downforce) at those kind of turns. However, this will slow you down at the straights.

4. you can also use less ARB at the rear,

5. you can put more weight to the rear. However, this may cause understeer at medium and high speed turns, and also at some slow turns since you will have much less weight to the front at the time to accelerate.

In a way, when making a setup you must assume some compromises and, imo, you will never get the ideal setup. What can be good for fast turns, can kill you at slow turns, and viceversa. You must take your choice, depending on the kind of track, i,e, what may work great at Long Beach, can kill you at Spa or Monza :)

Which mark are you using?
The fastest and easiest to control is the jag.
The sau is the fastest overall but is more prone to oversteer on acceleration exiting a corner. and it has weak brakes, so downshifting is required to help get it slowed down.
The maz is just slow. It requires maximum driving to get the top speed out of it, so over-driving it is a problem.
For me, the toy is just evil. I've tried other's setup with no luck and I don't have a clue what the base setup ranges are.

"How about weight balance? In the middle?"
If you're talking about weight location on the car, i.e. front to rear, then mostly front weighted. For jag, maz, and sau, full foward to 3 clicks toward rear depending on the track. I only drive the toy when I'm developing ai, I tend to have the weight from the middle to full rear.
