yep i have a vi spoiler on my 4 though it was already fitted when i bought it so could'nt tell you about the fitting's. would it be easier getting a secondhand boot with spoiler fitted. as i'm pretty sure that would bolt straight on. just a thought.(providing its the same colour)
yep a VI boot would be easier but probaly not cheap with a decent spoiler attached. I think it does fit but I will have holes. Im sure someone out there has already done this . Probaly hundreds as its a good mod
