Z31 rear rotor for 240SX bracket conversion - which year?

[Guest Anonymous]

I'm collecting parts for the 240sx rear brake conversion on my 76Z. I'm not doing the 5 lug conversion and so I need the year for the rear Z31 rotors with 4lugs. I think I've narrowed it down to the 85 turbo if it had 4 lugs. I'm aware of the na cars that had 4lugs, but are they the correct diameter. I can get Brembo locally for 49us. I have read that it should be the 11.4 or 290 mm rotor. Thanks.

My notes indicate the 1986-88 300zx had the 5 bolt lugs including some 1984 up early turbos. Check Ross c's site and you may find the years with the 4 bolt web page The site in the past had the info on the 240 sx swap

All turbos are 5 lug. Only 84-85 non turbos had 4 lug which are 4x4.5(4x114.3), same as s30's.

Also, there are two different rear rotors I believe. You want the larger 11 3/8 one. Do Ross a favor and buy the rotors from him!
