Main thing is to make sure you get front shocks capable for the extra weight of the vr6 lump. I think some people may even use mk3 shocks. Id get adjustable coilovers sold with springs as damper rates will be matched to the spring rates. If you want your car set up properly also have the alignment done and get it corner weighted. Think there is a mk2 vr6 track car on clubgti so you can probabaly find what shocks he is using.
