If you have more headroom on your wheelbase we could scale the strength in the FFB file higher, but if you are at a volume of ~90 and everything is "okay", I would leave it as is. If you are running at a volume of 100 and it's not clipping and the FFB is weak, we should increase the strength in the FFB file. The main idea is, you want to avoid too much clipping as FF details will be lost and your wheelbase will be overly stressed out for long durations. Some clipping shouldn't be noticeable unless you are ultra-sensitive. If you didn't know this already, when you toggle the HUD screen as you drive one of the screens shows you the FFB settings along with graphed real-time forces. The far-right verticle bar graph signifies clipping.No. Sorry for not answering this the first time, I've set it as a Logitech G29. Finally just won my first race in the GT4's. Previously to getting your setup, I could barely to a lap without loosing the rear.
I've attached a pic I grabbed from another forum. I don't think the force strength they list are correct. I believe they are the strength of the force at your wheel position or the angle of the steering, but the diagram serves the purpose for this topic.
