XRAY - Model racing cars

hi what is the effect of less rear toe in and what would you all recommend using on medium/high grip carpet with the new ride rex 30 tyres ????

Also what front and rear camber would you suggest ???

thanks

Less rear toe = less the rear sticks to the ground. And as far as the T4 car has the great rear traction, with less rear toe-in you have better cornering and less drag on the straight.
For me, in particular on REX 30 tires, it always worked the best with 2.5 degree.

On the tighter track I run on sometimes with 180 corners I found the car to be less consistent with less than 3deg rear toe.

A good starting point is rear toe: 2.5º, font camber: 1,5º and rear camber: 2º.
