Will these wheels fit my 96 C4S?
I am considering buying a used set of Fikses with the following sizing
Front = 8.5x18 ET 50 (stock is 8x18 ET 52) mounted with 225/40s
Rear = 11x18 ET44 (stock is 10x18 ET 40) mounted with 285/30s
Supposedly they were made for a 993TT, so they should fit my car, but just doing due diligence.
Thanks in advance

Hi Mike,
I spoke with Fikse at a local tech session and he recommended 8 & 10X18 for the street and 9 & 11X18 for racing for my C4S. I run 305/30ZR18 on my 11X18 ET43 without any problems on the back. I have also run the 285/30ZR18 on this wheel. I run 245/35ZR18 on my front 9X18ET55 without any problems. The centerline of your wheel sits outboard by about 0.20" (55-50) but the wheel is 0 .25" ((9.0-8.5)/2) narrower to the outside. So the 8.5X18ET50 you are looking at with 225/40ZR18 tires should not have any problems on the front.
