RabidPony--- Your new 16x8 wheels and Yoko AT-S (31.4" O.D.) tires should fit perfectly fine on your OEM stock VX without any kind of lift (no rear spring spacers) and no front torsion bar cranks.

At worst, you may only require a tad bit of cladding trim on the very front to possibly clear the front tire "swing arc" when turning (very common). The only other point of possible rubbing might be the famous inner-fenderwell "bolt" located at the extreme bottom-rear of the driver's side front wheelwell. Should the inner-fenderwell "bolt" rub, then it can simply be removed to provide additional clearance.

Never, never "pre-lift" your VX before mounting wheels/tires. Any kind of "lifting" (TB cranks/rear springs) should only be done AFTER wheels/tires are mounted and actually test-fitted on the VX, and only then if it is determined that "lifting" is the only solution (as opposed to additional trimming and/or BFH). TB cranks and rear spring modifications should only be a last resort (unless of course you actually want a "lifted" VX purely due to the "look").

The stock VX has gobs of extra space in the rear wheelwells for a 31.4" O.D. tire. Heck, I currently run 32" O.D. tires on my 100% stock "non-lifted" VX (no TB cranks/no RS mod's). Try not to touch your front torsion bar factory settings, as this will minimize any CV issues later on. Always try to keep your OEM factory suspension set at OEM spec, unless you actually desire a "lifted" VX because of the sheer "look" of a lifted VX. Only "lift" out of necessity; not because of the "look", your CV's will thank you later.

Please post some pictures after you have your new wheels/tires installed, as we'd like to see the finished product.
