What size brakes are on the IS350?

I went to the Lexus website to build an IS350 but I can't add the ML as an option.

IS350 uses big brakes from GS430 so look that up. I dont think site is completly functional yet - you can check pricing thread at tthe top of the forums for the ML pricing and you should be able to customer order it this way.
