I'd change the question to "how hard is it". Anything is possible. My wheels came from a '92 primera touring car that had been fitted with R32 hubs to make it five stud. Therefore, yours could be done by I don't know how difficult it is. Ring a tuner for advice. The two I talk to are Rod Bell at RBE on 01704 822848 or Mark at Abbey Motorsport on 01883 732331. Rod may have done the primera conversion and I am sure I heard Mark telling someone about the GTS conversion. Good luck
