JustinOlson Posted November 23, 2015 Share Posted November 23, 2015 (edited) Found out today Wilwood offers a rotor hat for our car that has a rotor bolt pattern of 12X8.75. This opens up a lot of options for rotor sizes. http://www.wilwood.com/Hats/HatProd.aspx?itemno=170-9294 I was thinking of going with the following combo on my 240z: Superlite Calipers with 1.875/1.75 pistons. 13.06" X 1.25" Directional Vane Rotors 12 X 8.75" Rotor Hats Are the caliper pistons too big at 1.875/1.75 for pedal effort with a 0.875" master cylinder? I'm still sorting out what I'm doing in the rear to match this. Edited November 23, 2015 by JustinOlson Quote Link to comment Share on other sites More sharing options...
johnc Posted November 23, 2015 Share Posted November 23, 2015 Most likely. I ran 1.750 four piston front and 1.375 four piston rear with a .875 MC. Quote Link to comment Share on other sites More sharing options...
74_5.0L_Z Posted November 23, 2015 Share Posted November 23, 2015 What size wheels do you need to be able to run those? Quote Link to comment Share on other sites More sharing options...
JustinOlson Posted November 23, 2015 Author Share Posted November 23, 2015 (edited) I imagine you could get away with 16" wheels since some of the 12.2" rotor guys are running 15's with the same caliper. This guy is running the 13" setup + wilwood hats with Rota Rb-R 17's: https://www.instagram.com/datsun570z/ Edited November 23, 2015 by JustinOlson Quote Link to comment Share on other sites More sharing options...
fluidmotion Posted November 24, 2015 Share Posted November 24, 2015 Great find!!! Thanks for the heads up. This gives us a great alternative to the brake options out there. Quote Link to comment Share on other sites More sharing options...
JustinOlson Posted November 26, 2015 Author Share Posted November 26, 2015 Here is caliper clearance based on rotor diameter FYI. This might help sorting out wheel clearance. Quote Link to comment Share on other sites More sharing options...
clarkspeed Posted November 28, 2015 Share Posted November 28, 2015 That is pretty cool. But those rotor choices are enormous, heavy, and expensive. I am taking my setup from 12.19x1.25 down to 11.75dia on a 8 x 7 BC. Common as dirt circle track size, cheap, lighter, and more than adquate for my application. Still pretty cool they released those.
