I would certainly hope that TSportline, as a company that sells very high-end forged wheels, would also ensure the appropriate level of manufacturing quality and testing went into this cast offering. They have already indicated they use a low-pressure cast, which is a cut above cheap replica wheels, which are typically gravity-cast. Sure, I wish I could buy an OEM Tesla wheel in a Grey 19" Turbine style...but I have been begging them for this since 2012, and it isn't available. They make a grey 19" Cyclone wheel, but I can't buy those either, as they were almost exclusively European. I have begged Ownership to make those available in the States as well, as yet to no avail. So in the meantime, I will try the TSportline TSTs, which sound like they should be stronger than the Rial Luganos I run for Winter wheels, though I haven't had any bent rims on the Rials, and I think they look fantastic.
