Since the IC location is determined in the same manner for both 3link and 4link suspensions, the distinctions made regarding the roll understeer/antisquat problem are unwarranted.
Also, it should be pointed out that roll steer characteristics involve only steering input and are not related to the dynamic considerations related with under/oversteer caused by weight distribution, etc. In other words, an increase in roll oversteer will never result in a critical speed. So, in many forms of motorsports...particularly dragracing..., roll oversteer is only a minor consideration, dependant only upon the tolerance level of the driver.
