Do Dymags break?
Just wondering if anyone has seen a Gen 1 Dymag break due to stress cracks? I'm in the process of refinishing a set, and was wondering if it is necessary to have them x-rayed or dye-tested, an fairly expensive operation. The car will see track duty. Any help would be appreciated.

if they're painted then the paint would have to be removed to dye penetrant, x-ray(the most expensive) just need to be super clean. We also eddy current them(the cheapest process) just need to be clean and no loss or pealing paint.

When I first got my set of Gen I's and had them stripped, one of the wheels had a very small stress crack going radially outwards on one of the lips, it was very small, maybe 1/2" long. I showed it to a friend of mine who was an absolute welding master and he told me it was probably due to the material "setting" much like a typical casting. Anyway, he welded it up, lightly filed it, and soft wheeled it and then I had it refinished along with the other 3. You couldn't see the crack through the OEM paint so I suspect he was right and it had been there all along. I would just have yours stripped and look them over very carefully and if you don't see anything go forward and have them refinished. If you're still wanting to have them X-Ray checked it certainly wouldn't hurt anything except your wallet.

I would say it depends on whether or not the magnesium has had the opportunity to oxidize b/c of finish chipping off. That can weaken the metal.
I sent my Dymags to Ye Ol Wheel shop, they went over the wheels then refinished them. I know they were tested to 175mph
