I hear ~4mm at the least for clearance. Is yours closer than mine? 380mm 6 piston rotora fronts pictured with 18" TE37SL, Titan 7 T-S5, and APEX EC-7. Done about 14 track days with the BBK on, no problems with clearance so far. Are the NT03 wheels design to clear BBKs? That's an important factor. I know Brembo calipers are larger than most, so if your AP Racing ones are large.. maybe that's the issue too
