Ronal Turbo wheels questions
 

Hey guys i am new to this forum and was wondering if you guys could give me your input on some wheels i have laying around my house. I have been trying to figure out what they are off of and have been trying to seel them on VWvortex but have had no luck nd after doing some google searches etc i am starting to think they may be a mid to late 80s porsche wheel. They are Ronal Turbos but unlike the common 4 bolt style (which is all i have ever seen) these are 5 lug ronal turbos (5x4.75) i measured backspacing and i believe it is an ET of 6...may have done something wrong but i believe that is accurate. If anyone knows about these wheels and what they may be worthfeedback would be appreciated
