I use Tarett Porsche caliper studs instead of bolts. This allows me to just remove a nut on top. This is how the caliper was designed. Brembo cheaper out on their street kits, IMO.
I’m low on engaged threads but at least past the minimum. Tarrett doesn’t have quite the ideal length on the top, unfortunately. Longer studs increase both the bottom and top lengths, and I would run the risk of hitting the wheel. Been running this setup all year without problems.
