What are you using for your diff centre?
Don't worry about lock mods until you're actually limited by the stock geometry. The two biggest issues you're gonna face with a VS is actually finding decent suspension and the crappy hand brake. There are a few companies that make coilovers but I can't say any of the seem all that great (they all seem to do a one size fits all approach, no choice of spring rates etc...), plus the strut top mount that the VR/VS uses is kind of awkward so it's more difficult to swap another off the shelf coilover in. That and the power steering may have a tendency to overheat (just keep an eye on it and worry about it if it's a problem).
XYZ coilover kits might be a good starting point (I've never used them). Also choosing wheels with a decent width/offset with slightly more track at the front will help.
