I don't know...I kinda like like the stock wheels on my 355. Why change? BTW, can't imagine having that additional front black spoiler on that pictured 355. I have trouble clearing driveway aprons now! Looks nice tho.
19" wheels work very well on 355's, try to match the weight of the rim as much as possible, go for the lightest rim you can fin in a style you like, to my surprise mine are only grams heavier than stock. It's only 20 bolts and your back to stock.
there is a pic floating around with similar wheels on a red 355...i think they were champions....no longer available...
