Those with KW V3 - front spacers needed?

[NZ_M3]

I know there's a few of you running the variant 3 - the official installation spec notes that front spacers may be needed - I remember seeing a post by a member on here where the stock wheels rubbed the front spring perch (or was very very close) - can any owners confirm if spacers are needed for the front wheels, or is it only if you drop the front end real low? (if so what ride height before spacers are needed?)

Thanks.
