I'm running 215/45/17 also

I had tab problem even before i lowered it 30mm then it got worse , i didnt know the reason for the noise it created untill after i lowered it.
Cut away the tab as above then no probs

I think i had problems before it was lowered because of the offset of my alloys.
My ride is still on the harsh side but i think it may be due to having cheap tyres

Cheers
