I ran some Sport Editions on my AutoX car last year, they actually looked and felt really well made. I wasn't expecting them to be that nice given the price point. They also balanced up easily with zero problem, even after heavy use.
Both with Sparco and OZ wheels I have run into minor issues with them being slightly out of round and being a real pain in the butt to balance up.
Actually, I did a little bit of digging. Sport Edition is made by the Japanese company Kosei, made in China, with modern low pressure casting process. They are designed to meet German TUV standards, so they should be just as durable as the OEM wheels.
Poorly designed center caps can definitely fly out under high heat load. Lost one of mine off my Rotas on a mountain run with heavy downhill braking. After that I secured them with non permanent adhesive.
No complaints about my Rotas otherwise.
As far as wheels melting, lulz. Bending or warping might be the word he was looking for, I wouldn't worry too much for our applications. Personally I would lean toward budget wheels for recreation track use.
haha, on my Audi one of my OZ wheels kept losing a cap... I replaced it twice, and it wasn't cheap! I finally used some plumbers adhesive to stick it in there. The other 3 have been fine otherwise.
Nothing wrong with Rota's, they were my go-to cheap wheel before. Again, lightweight and cheap. I wouldn't run them on something like an M4, but for cars like ours they are perfect.
