Hey Groovedaddy, I just purchased a 2001 ody and here is what i have found so far.
suspension: Eibach and H&R both have lowering springs for the ody
Wings West makes a wicked body kit, not gaudy but will improve the appearance considerably.
Max tire size that will fit on this van is a 255/40 R 19 on 8" wide wheels with a 42mm offset.
Comptech makes a Header and cat back exhaust system for it.
I'm just waiting for Compteck to make a supercharger for this baby. With the header/cat back combo and blower one could expect to wring out in excess of 300hp with moderate boost.
