I've looked extensively into the 6-piston 355mm Brembos. They're not going to fit 17" rims. The dimension from the center of the wheel to the outer edge of the caliper is 210mm (8.26"). They won't clear my 18" Advan RS wheels (there is no spacer needed, the barrel dimension is what won't clear). The 4-piston 355mm system is 200mm (7.87").
Check with Stoptech. Their 6-piston 355mm brake system runs 199.5mm (7.85").
Measure your wheels and you'll know what fits.
