So my girlfriend and I are branching out from auto-x and I'm starting to prepare for some track days this season. I'm rounding up a couple of sets of 15" wheels to make use of used/cast off Toyos. My question is how do you check for cracks and such on older alloys beyond a thorough visual inspection?
I've got a set of 3 (used to be 4 before a catastrophic brake failure at an auto-x back in '03) used aftermarket 15X7s I picked up at Import Carlisle. There is no manuf, name anywhere on them, I'd guess they were made late 80's, early 90's? They look to be decent quality, but I'd rather not find out at speed on a road course. Any advice? I won't be looking to use these particular wheels until next season as they are currently wrapped in rock hard RT-215s holding up the front of my old 89 hatch in the back of a storage unit.
