Sorry in advance for the long tread.
I have a set of snowflakes on above mentioned astra.
Fitted 5 stud hubs ,308's and a clet engine.
I have a Eibach 30mm suspension kit fitted for a 1.6sxi.
My front tyres,size 215/40/17 are rubbing the inside wall of the tyre on the bottom of the spring seat on the strut.
The rear tyres are catching on the 2 screws retaining the plastic guard
inside the wheel arch. But size on the rear is 225/45/17.I know they are too big but that is how I bought them a mk4 zlet.Must say they are geat in tight corners! The front size is more worrying as that is supposed to be oe spec?
Hope this querry makes sence.
