Two different cars, same issue...unsure of how to go about it

I have two cars in A class. Maxda Rx8 and the 2013? Mustang (the newer one). Just trying to have some fun with them.

Anyways everything seems fine, they handle great but…one issue. When exiting a turn, I start increasing throttle. The back end doesn’t spin out but the tires seem to lose traction and overheats quite quickly. Usually for a left turn the back right tire overheats and spins a bit and if I make a right turn the back left tire spins and overheats a bit.

Is this a simple tire pressure issue? Camber? or something else entirely.

The inside tire spinning free is a result of multiple issues, and the fact that your car isn’t spinning 'round from it indicates another.

From my experience, the inside tire spinning is due to a differential setting that is too low, a rear rebound setting that is too high (think of accelerating through a right-hand turn, if the outside rear tire loses traction first there is excessive rear bump and if the inside loses traction first there is excessive rear rebound), or an overly stiff rear sway bar.

In your case the outside rear tire is lighting up first, so the rear bump is settling before the front rebound (think of the back right tire versus the front left corner of the car). Remember, springs & ARB’s are steady state cornering adjustments (mostly), and damping, toe, and caster are dynamic corner-entry/exit adjustments. If it’s losing it after the middle of the turn, you need to figure out if it lets go abruptly or slowly. Abrupt is suspension travel, slowly is damping/ARB/toe/caster/spring ratio… you get the idea I hope. Did this help?

Yes I believe it does help. It gives me something to zone in on and try. thank you.
