19" wheels for 1996 carrera 4

Model: 993 carrera 4, Year:1996, Mileage:79000, Type of use:Street use only
Can you put the 19" carrera S "crab claw" style wheels (from 2005 carrera S model ) on a 1996 Carrera 4 (narrow body), or are 18" wheels the maximum dimension possible without modifying the fenders/etc? If the 19" wheels can be placed, what suspension/spacers-setup is needed? Did porsche make an 18" crab claw" style wheel? What suspension modifications are needed/spacer setup for 18" wheels on 993 narrow body? I just think the 18" wheels look much better than the 16-17", and I would like to make a change from the standard 17" cup wheels i have. I use the car for street use only. Thank you for your help!
