Think about what the FRORF kit gives you before you compare apples to oranges. It not only solves inadequate braking, it solves inadequate axles. And it does so in a bulletproof manner. Want e-brake? Use the Supra calipers and have the kit made for them.

None of the other kits you mentioned are made to the same level of precision nor engineering. Certainly not Sky.
