HELP---has anyone upsized their wheel/tire package on a late model DINO 246GTS? I've done a search and can't find complete info.... Need help w. your sizes: 1. Wheel sizes front and rear w. offsets? 2. Tire sizes front and rear? Also, if anyone has switched factory wheels from other Ferrari's to this one, please provide info above, and if any spacers, modifications were required--tire sizes too. Thanks in advance for any help...and our customer too!
