Brembo Brakes
They are showing the P30 with dual rear wheels with both the I-Beam and the independent front. They are also showing the P30 with single rear wheels and not identifying, I-Beam or independent front. I don't think the single wheel rotor will fit the dual spindle.
I am afraid that unless proof of a I-beam, single rear is found, this may unfortunately be a dead end.
One source said the P30 dual is 10,000GVW and the single wheel 7,000GVW.
