Now that the X has gotten a new head, its time for suspension! Rear coils are broken, so deciding between shocks and struts. The B4 and Konis I can get at basically the same price, so looking for experiences with either. Id normally go with the B4, but the Konis are on sale bringing the price down by 150. Im also considering the B4s from the sport package X3 for a little more, but want to confirm the springs are correct. Thanks
