the closer your shocks are to a 45 degree angle the more bodyroll you will get. but it also depends on what shocks you plan on running. Some of the more quality shocks, will lessen the problem even at a 45 angle. the way I look at it is, you cant have it all. If you want good flex from springs and less shock angle resistance, you are going to have alittle bit more bodyroll. No bodyroll means probably a stiffer ride and possibly less travel. just my 2 cents
