In fact, IMO the stoptech design is even easier than the brembo F40/F50 design, removing and installing those pins is more difficult than removing the bridge.
The speed of changing pads on the 6pot kit is kind of a moot point anyways for the E9X. The only available brembo kit is based on a 380mm rotor and is not very club-racer friendly. I wouldn't run an 18" wheel with that size rotor, and there are very few r-comp tires available in 19" sizes.
Stoptech is launching a 355mm kit that will probably be much more popular with club racers and HPDEers. Assuming the stock system does not hold up with racing pads and fluid, this is likely the way I would go - strictly for practicality and usability though.
Great info! Thanks for sharing
