Personal thought..Maybe a little Dad(ish) but...
Why not go for 16" and lower the car instead ??
1. Easy to fit
2. Will handled better
3. Will not scrub
4. Will not destroy ball joints
Alternatively sell it and get a 172 ( prices are very good at the moment and if you can't afford to insure it then found out how much declaring your 17" wheel modification to your insurer will cost you before you have accident )
