Since your car is already 99 spec, then things could be easier. The only thing that make the Vi-RS unique than the normal EK3 spec is cosmetic changes which loaded with CTR front end, more like our local Wira SE.
The Vi-RS was souped up with nice interior with blue seats, unique climate control with "Vi-RS" printed, unique gauge cluster with "RS" printed, unique body decals, "RS" badge and a CTR front end.

Basically, the front end is exactly like the Type R so people will know better if you tell them you are looking 99~00 spec Type R headlights, grille and front lip.
Vi-RS stuff were hard to get and almost nobody selling it couple years back. Now you can get the RS badge, body decals and Type R headlight brand new from Exceptional Auto Parts (03-56332861) in Subang Jaya.
The seat, gauge cluster and climate control are very hard to come by though. You might wanna find Low Ju in the insdustrial park around the Giants in Subang Jaya, sorry I lost his phone no. and forgot his shop name.
