According to BAT and SP motorsports, the plain BAT kit is a better choice, with the euro struts...they are valved more specifically for the springs and are over all a better fit. They did mention though, that the difference is minimal, but since the bilsteins cost an extra $100, they say it isn't worth it. I on the other hand, might go with the bilsteins anyway in hopes that they will last longer, and keep the car a little higher, even if its only an 1/8 of an inch. Did you think about the spax adjustables at all?
