Greetings from all the way over here in Norway folks, I'm a spot of trouble that I'm fairly certain someone here can help me with.
Long story short, I work at a tire dealership and I have a client looking for a set of wheels for his Pantera with Group 4 fenders, the car is not an original 4, though. (I'm not sure if that makes a difference) I have 2x 345/35R15 Pirellis, will those clear the back? And we're not sure of the ET, backspacing and all of that stuff, as we've never touched a car like this before. Any guidence you might have would be greatly apreciated, thanks in advance - Daniel / TireKid
Daniel- one of your countrymen in Taasaavelen has a set of front & rear wheels for a real GR-4 for sale in the POCA Newsletter that he recently had restored. This is a good idea since cast magnesium age-hardens and gets brittle even if sitting on a shelf, so needs annealing every decade or so to reduce stress build-up. Racing wheels look identical to the street versions. PM me for details.
Note that real GR-4 wheels were made of a different 'Elektron' mag alloy than the street versions, and real-race wheels were 10 X 15" front & 14" x 15" rear. Street rear versions were 13" x 15". Both are horribly expensive so I advise first attempting repairs on whatever you have now; contrary to what you may hear, cast-magnesium wheels CAN be TIG-welded with the proper alloy weld sticks. It doesn't always work- depends on the welder's skill and using the correct rod, but you never know unless you try.
