XRAY - Model racing cars

Hi, can someone please explain what the difference in car characteristics this does and what situations you would use them in. In the uk would we class most carpet tracks as medium grip?

Thanks

Low grip,700/1000 cst is ok,high grip 2000/3000 is better,

The more thick oil make the car easy to drive, because is more stable in braking. The soft oil you can get more steering in the middle of the corner.

With soft oil increase off power steering at turn in but not so stable car and with thiker oil decrease the of power steering and increase on power at the midle and the end of the corner. This changes from track to track and all conditions. Especialy the grip:-)
