Tyler Posted July 14, 2010 Share Posted July 14, 2010 Since I have some toyota 4x4 4-piston calipers and 300xz vented rotors with spacers in my possession, I was a bit curious as to what other rotors would work. I have sitting in my garage stock size front vented rotors from my 2002 Sentra SE-R SpecV. They are 4x114.3, same hub thickness as the 300zx with spacer, butare a bit larger in diameter. The 300zx rotors are 10 3/4" across and the sentra rotors are 11". Has anyone tried using these before? Any other measurements that need to be taken to ensure proper fitting. I may try to fit them when I do my swap to see if anything can come of this, but I'll end up using the 300zx rotors since they are new and cross drilled and slotted.

softopz Posted July 14, 2010 Share Posted July 14, 2010 Other important measurement is the offset from hub to rotor or backspacing. If its only the diameter that is different than you can still install it but you will have 1/4 inch of unused rotor. You can fix that by turning the rotor to 10 3/4. goodluck Quote Link to comment Share on other sites More sharing options...

I'm wondering this because people use the very large 300zx non-turbo rotor with 240sx calipers for the rears (the rotor is huge in comparison).

NZeder Posted July 14, 2010 Share Posted July 14, 2010 (edited) one quick thing to point out is the 240z/260z/280z/280zx and the 4 stud Z31 300zx rotors are not mounted using a 4x114.3 PCD but a 4x103 PCD to the back of the hubs.

Ah, thank you! I didn't know that. I guess scrap this idea. Quote Link to comment Share on other sites More sharing options...
NZeder Posted August 1, 2010 Share Posted August 1, 2010 Ah, thank you! I didn't know that. I guess scrap this idea. well if you have to machine the centre bore from 68mm to 81mm you can also redrill for the correct mounting pattern at the same time.
