To best way to lower the VX would be to get some custom springs made for the rear from Valley Spring Works and then lower the front by simply adjusting the torsion bars. The last time I checked, Valley Spring works would make a custom set (two rear springs) for around $200 possibly a little cheaper if you get a few people together to buy the same springs at the same time. Anyway, after you lower the front by loosening the torsion bars, you will want to get the front end aligned very soon... it knocks the alignment WAY outta wack. I of course went the other direction... 2-3 inches in the rear via OME lifting springs and then cranked the torsion bars up front. Anyway... good luck and post pictures if you do it.
Later!
