yeah they are hired to check the vin and engine number. i went though the pits 3 times and didnt have an issue. although the last one was the pulser and it had the dodgyist paint job and the guy look at it funny but let it go as that isnt a rwc issue..but it took me a while to get the rwc. had to change everything back to stock. turbo, exhaust, remove cooler, make it low mount and a heap of shit
