Linking the front is not going to cost you that much more. Personally I think using leaf springs in the front on a Vx is going to look like *****. To do a link suspension you don't need coilovers. You can use coils and shocks. Some things to think about before you jump into this is to keep your ABS and TOD you will have to remount all of your speed sensors onto the new front axle. If you don't do this you will need to put a non TOD case in.
