How much steering depends on your settings (toe in/out, caster, camber etc...) and your front tire grip. Different cars will have different % also because the front end design is different.
My CRC requires about 90-100% while my 12x only needs 60%.
Not Sat's, as I have 1/2 day work so it will be too dark if I come after.
Also, what do you mean by 'stiff in cornering'?
Steering is usually 'oversteering' or 'understeering'.
Oversteering will leads to car easy to spin, but will give you tighter corners.
Understeering will push the car outwards, but easier to handle/drive.
