XRAY - Model racing cars

Serious oversteer problem on my 08 NT1 when off throttle cornering, the car will spin when before enter the mid of corner.
I tried the whole set up at:

-Downstop: F 1, R 4
-Spring 1.6 ID for F/R
-F Toe-out: 1 degree
-R Toe-In: 2.5 degree
-Track width: Following standard setting, 198mm F, 200mm R
-Roll centre: As low as possible
-differential oil: F 80000, R 60000
-Shock oil: 600
-Front stablizer: 30 degree
-New lower plate

I think this is so common setting, I don't know why the car can't handle, seems the rear has no grip. Any idea?

what tyres?

This can also happen when the rear tires are smaller than the front.

I had the same issue when switching from 37sh to 35sh frt tires. Switched back to 37sh and back to normal. Local experts said too much front traction causing my issue.

Try it:
Front antiroll bar stiffer. (vertical)
Harder front wheels.
Harder springs (red, purple)

hi, I had the same problem, lowered the F/R upstops by 1 and lowered the car 6 F;8 R, 2mm split 24Mid pulley, F springs red, 90degrees anti-roll, Rear Matrix 45, Front Matrix 42

it might not be such a preoblem of the rear but of the front. When you have too much steering the car doesn't handel correctly and it might seem as if the rear is too loose, but acctualy the problem is in front. Try to reduce steering of the car with as much set up changes as you can imagine. As it has been told prevo¡iously, harder roll bar, thicker front diff oil.

I would also try a harder rear roll bar, it might just help and it's something fast and easy to change.
