Steering Wheel with FFB

I use to drive a F430 FFB Sterring wheel without the Feedback. Of course, when I dont use FFB I must get some steering Help 19% or less. Turning the FFB and Steering Help(F8) off at same time, its impossible to drive.
If I have the FFB on, i dont need steering help. But the feedback seams to be too strong, even with 1% factor.

Iam driving now 1980mod. My question is: Had the cars really so much Feedback? And is there a way to decrease more the FFB?
