Very true. When using splined bars, like the ones from Speedway Engineering, There is a lot more tuning available. Length is important, as a shorter bar is stiffer that a longer bar. Speedway Engineering has rate charts on their web site that are very helpfull. When using this type of swaybars on trucks, I try to keep the rear bar rate at appx 80% of the fron bar rate. This is also dependant on driving style. Arm length of the bar is also a factor, and can be used as a tuning tool.
