ok, got bored again and played around with the aperta wheels on my spider, and it turned out to be a perfect fit.
Basically the aperta wheels, or all the FF wheels will fit much better than the stock 458 or any other 599/612 wheel.
The Aperta rims are the same size front and back as the stock 458 wheels, but with a better 1+cm more aggressive offset in the rear which make it stick out awesome and perfectly flush looking. The GTO spec PSS 315/35/20s were mounted on the aperta so it look fat and donut-like on the spider. If i were to go with these rims, i would put stock 295s or even 305s and it wont rub. Inner wheel well clearance is plentisome, just with 315s, the outer rim might rub over bumps.
a better question is that we can fit lighter 458 rims on the aperta, because stock aperta rims are heavy, i think its the same or even heavier than the stock 458 rims, and definitely weigh more than my HGTE ones.
I wanted GTO rims on my spider but it will force me to use bigger tires like 255s in front which my tire shop doesnt recommend saying it will understeer greatly.
I didnt weigh the Aperta wheels because i dont see my spider with them rims.
but i can definitely see myself in an Aperta!!
i never been in a GTO at full song, but in a aperta it was a religious experience, it feels like a scuderized 599 with a rawness and sound i have never heard anywhere. I never use the F1 cliche, but i think i can forget the F12 and not return the keys on an aperta =)
ok, i just wanna play with all the stock rims, so dont ask me why, pics:
