92 Mondial wheel possibilities?

peter haefner · 01-13-2003, 12:50 PM

I have a 92 Mondial t cabrio.....

Factory stock wheels/tires are; front: 16x7 205/55, rear: 16x8 225/55

When I bought the car it had and still has Kinesis K20 wheels; front: 17x8.5 245/40, rear: 17x9.5 P275/40 and they both fit perfectly to the contour of the fender

I would like to change these wheels to a factory Ferrari wheel, either the:
355 style; front 18x7.5 225/40, rear; 18x10 265/40 or the
Maranello style; front 18x8.5 255/40, rear; 18x10.5 295/35

CAN IT BE DONE? With or without adapters? I want to keep the tire/wheel/fender contour..... HELP!!!!!

Bolt circle diameters should be the same, but watch out for the center hole diameter (the hole where the plastic prancing horse logo goes) and measure the offset of the 355/550 wheels just to be sure it'll match your old rims.

Take a trip down to your Ferrari dealer to see if they have rims off of the cars in for service and ask to take measurements.

Don't quote me on this, but as far as I know, they should bolt-up without any spacers/modifications...

I should add to my first response, to make myself more clear: In reference to the center hole, measure the diameter from the BACKSIDE (the face that meets up to the brake disc)...
