Meph Posted May 10, 2013 Share Posted May 10, 2013 Hello, I've been searching google for the past hour trying to find my answer. I'm trying to find which rotor I need to order to replace the ones on my current rear disk conversion. I'm not sure exactly which kit I have, but it looks like 240sx calipers with the CNC'd hangers. 4 bolt. All website just refer to the rotors as 11.4" slotted drilled. Probably to make it difficult for others to piece the kits together themselves. Would the standard rear disk of choice be a 300zx? 1985? NA or T? Anyone with info, I'd really appreciate it.

beermanpete Posted May 10, 2013 Share Posted May 10, 2013 Why not take your current rotor to an auto parts store and match it up? Quote Link to comment Share on other sites More sharing options...
richracing Posted May 10, 2013 Share Posted May 10, 2013 Try 85 maxima. Your kit sounds like mine. Quote Link to comment Share on other sites More sharing options...
Meph Posted May 10, 2013 Author Share Posted May 10, 2013 The odds of a part store in Canada having 1980's brake parts in stock to compare to is something they'd laugh at me for. The 85 maxima rotor looks like it has studs pressed in? Mine is the basic slip on style they held tight by the rim. Quote Link to comment Share on other sites More sharing options...
str8pipez Posted May 10, 2013 Share Posted May 10, 2013 280ZX maybe? Quote Link to comment Share on other sites More sharing options...
richracing Posted May 10, 2013 Share Posted May 10, 2013 That's right, my bad lol. The kit I have uses 82 zx rotors, and 85 maxima calipers. Quote Link to comment Share on other sites More sharing options...
richracing Posted May 10, 2013 Share Posted May 10, 2013 I bought mine from a company on Ebay if that helps. You can check out my build thread to compare and see if that looks like what you have. Or I can post pics of mine on here later when I get off work. Quote Link to comment Share on other sites More sharing options...
seattlejester Posted May 10, 2013 Share Posted May 10, 2013 I think it may not be listed because a stock off the shelf replacement may not exist. My kit requires turned down Z31 300zx rear rotors. Quick google seach says specs are 11.417 inches with the 4 bolt pattern. Quote Link to comment Share on other sites More sharing options...
Nigel Posted May 11, 2013 Share Posted May 11, 2013 These are the dimensions for a 1984 300ZX NA rear rotor for comparison. Pretty sure this is what you need. This information can be found on-line for just about every rotor available for sale. Nigel Quote Link to comment Share on other sites More sharing options...
Meph Posted May 11, 2013 Author Share Posted May 11, 2013 (edited) 1982 280zx rear rotors are the winner! I check mine out, same as the 300zx but 258mm diam. ( I rough measured 254mm so im pretty sure its the one, hub measurement was right on. Thanks a lot for the help.
