You will need 12mm hubcentric spacers and you can get them from Alfisti.net. You will need longer wheelbolts as well but Alfisti sell them with spacers.
Any spacer less than 10mm will mean the wheels sit too far in the arches and will affect the ride and handling.
Non hubcentric spacers are dangerous and should not be used.
10mm spacers are not strong enough due to the hub size but these are closest to OEM offset.
12mm spacers will only widen the track by 4mm and are a safe size to use.
Don't even think about using spacers with 147/156 wheel bolts!
