Or maybe nobody has any experience with adding upgraded struts to stock springs?
Not a common upgrade. It would work though.
Also, is there a how-to on the 24mm Sway Bar?
Sure, but I think they're in the performance forum. The suspension forum wasn't around when people were installing them.
Here is a good post on the bar from the mailing list archives.
What compenent springs are you talking about on BAT's page? The sport spring sets? Or the "coil springs"? The former would work, the later are for their coilover conversion kit.
