Can I put this alloy wheels from Alfa romeo 145 (15/195/50). I found Alfa specifications for wheels and I hope soo that fitted to my car Stilo 1.9 JTD 5d.
You can (though I'm not 100% about the centre bore on a Stilo), but I reckon they may look a little odd. I'd test fit them first perhaps or photoshop it to see how they'd look - apart from the design, 15" alloys don't look very big on a Stilo so they may look out of place.
Have to say, I was considering something similar myself but mainly looking at GTA alloys from a 156/147 - different fitment though
