i mean, i've always wondered, when buying certain parts, such as zimmerzhong rotors for instance, where they are really from, how do we know that factory is legit, etc. i think we can all put some serious coin on most of the 'ECS' and 'CTS' parts they sell as being the exact parts you can get from alibieblala and ironing their stickers on them.
It seems to me, Cicada did his research pretty thoroughly here, possibly indeed cutting out a middle man like a porsche dealer or a site like ECS tuning. At this point it seems a little more likely this is the case than him buying some serious QC issued riddled factory trying to roughly mimic braking parts that may or may not catastrophically fail.
As he pointed out, this factory has been in business for, what was it, 17 years or something? That is sometimes the ONLY indicator that perhaps they are legitimate.
I say full send it on an empty road with plenty of room to stop - just remember, your electronic e-brake does not work while in motion. the car only makes ~260whp anyway
