On a typical Honda that's going to require pretty mad camber on the front to over come the lack of bite that the car would normally get from the radical weight transfer to the nose.
What you didn't mention in your otherwise correct observation was that these same people will have 3.5 degrees negative camber on the front to get the car to turn w/out having the weight transfer.
On my DC2 ITR hybrid track car, I still have the OEM sway bars, but 14K on the nose and 16K on the rear. 2.5 degrees negative camber.
14K on the nose will help keep the nose up when going into threshold braking from about 140 miles per hour, but the higher springs on the rear will still allow for decent rotation in the corners.
A lot of our cars are getting very old, now, and much of what is perceived as handling anomalies is the result of the rubber suspension bushings simply having too much wear.
