One, never heard of this brand. What kind of credibility does the company have? Do they participate in motorsport where the product is put to a real-world test?
That's a very good question. Seems kind of odd that a relative no-name brand in aftermarket brakes would all of a sudden be jumping out there with an entirely off-the-shelf large 6/8piston caliper and floating rotor kit. I'd figure a newcomer to the business would start off selling aftermarket rotors or rebuilt OEM calipers or large rotor retrofit kits with OEM-ish calipers.
I honestly have to wonder if this company either is a con or / is selling other company's parts rebadged as their own or / is a real company but in an obscure market that we're not familiar with (say, Russia or China)
Two, all their BBK have the same picture. Are all their product just one generic kit with different mounting bracket? Would master cylinder be able to support it? How about brake balance?
Technically speaking, even the Stoptech BBK's are all the same. They only have three different caliper sets (ST-40, ST-45, ST-60), they just have different piston sizes to accomodate different vehicle requirements.
As for the master cylinder, good question. But, that's also a function of piston sizing.
And as for brake balance, your guess is as good as mine.
However, one thing nobody has touched on yet is ABS - How do these brakes function with the Toyota ABS system. I see steel braided lines which help, but hopefully the piston seals are up to the task.
