yes i am sorry, the Z rotor is 10.9 inch. i misread a article wrong. if you want some more info about brake upgrades, there is an article on sport compact car's website. http://www.sportcompactcarweb.com/te...cc_projsilvia/

if this helps at all, here is a part of the article that might help

2: Use cheaper brakes.
If you aren't planning on making 300 hp, or plan on using it only on the drag strip, Brembos or even 300ZX brakes are overkill. 10.9-in. '90-'96 Infiniti Q45 brakes use 10.9-in. rotors with large, two-piston sliding calipers, and bolt on if you re-drill them for a four-lug. The 11.6-in. brakes from the '97-'01 Q45 should fit as well, be we haven't tried that. -Sport Compact Car
