im not into racing much, only once every couple of weeks when i drive the 103 miles to denver. im just talking about general bash handeling. no the shocks arn't bottoming, but when the front end can absorb the bump very quickly (thin oil) and the back absorbs it slower (thick oil) this will cause the back end to lift therefor kicking it side ways. equal shoch oil weights with soft springs in front and firm springs in back would do the same thing. its a big ballancing act to find what combonation work best for the type of surface your're running on. the great thing about the shocks is that they ary easy to get to, and oil is cheap. so pick up a few different weights end experiment.
