Hello to all ant thank you for your time, I found this car, its a 1979 Turbo but it has been all it's life with the wheels and aero parts. Any ideas on whom might be the tunner of this car, just trying to find out more about it.I don't know if there are other changes.

Do you know what the VIN is?

The 1979 930 was delivered with 16 inch wheels. The 15 inch BBS's shown on this car were aftermarket additions. I have seen them mentioned as dealer installed options, although never confirmed.

The rear vents were trendy add-ons to many '70's 930's (in various degrees of workmanship). These, along with "sloped fenders" and "boxed rockers", were so popular that they became Porsche factory options.

Thank you, the ones at the rear bumper are the ones that i haven't seen on any other. Vin shows it as a US 930

 

I can confirm a lot of USA dealers stocked those mesh BBSs in their accessories boutiques. Some cars may have even been delivered with them, but would have obviously been dealer add-ons and not part of the original factory build. You'd have to have a paper trail to an original bill of sale to probably prove that now, otherwise they could have just as easily been added years later.

I dont think the fender vents were official factory X/Z code options until the 1986-1989 cars returned, but Porsche may have Sonderwunsched them on the 70s cars. I cant tell from pics if its factory or aftermarket. Since its a USA car, perhaps the newfangled Porsche PPS (formerly COA) can shed light.

 

rear door gaps seem horrible wide. so i think this vents were later added. may be theychanged out the whole thing.

 

I have found a similar "strange one"
see my post here:

some user think that it is not original, but from the comment made below by Porsche 930 it looks that air inlets and BBS wer Porsche options at that time...

every day more confused...
