This setup holds the line so well that it is both an advantage and a disadvantage, meaning if you are on the corect line you will hold it. But if you miss the line you won't be able to get back to it without braking. The last thing I noticed is that with the DFP your setup feels heavy in the steering wheel (literaly, it takes quite an effort to turn the wheel).
Zeratul, I tuned it on r3/r3 hence the "grip grip feel" on r4/r4. Your right about the feel of the car, it's really on the road. The car was like that in gt3, that's why I chose it.
