I've been offered a set of 17" alloys (17"x7") for humble money which will fit the mk4 Astra that I have. The only snag is the offset is 38 or 39. I know that the Astra offset is 49 what sort of difference will this mean? Does this mean that the alloy will sit further in from the arch? Would there be a chance of catching the shocks? Would fitting spacers and longer bolts bring them out to help fill the arch or is that a stupid idea?
The suspension is standard at the moment but am planning on lowering it 35 - 40 mm after christmas.
Any help would be great.
