So I recently purchased RX7 calipers along with the necessary brackets/hardware but I bought the rotors separately. So my question is... what do I have to get machined on the rotor? E30tech has been down for a while so I can't really look at the write-ups there :/. Thanks in advance

You actually need to bore the center of the Corrado rotor from 65mm to 66mm.
The wheel hub bore is 57.1, but where the rotor sits is larger.P.O.S 1989 325is - aka Project Sh*tbox

PM me if you have any other questions. I have this setup on my car and can get you pics or measurements if needed. Definitely worth the work.P.O.S 1989 325is - aka Project Sh*tbox

I hear you there. I have to run 10mm spacers up front to clear my 15" wheels. I have some 16" Volk te37 knockoffs that will go on in the future which require 20mm spacers but I needed them anyway since those wheels are et40 (found a deal I couldn't pass up).
I'm actually looking into developing/building myself a 310mm big brake kit to take up more of that space but use the Rx7 caliper if possible. Plan on doing autocross but she's my daily right now.Last edited by badwella; 12-21-2016, 03:26 PM.P.O.S 1989 325is - aka Project Sh*tbox

EDIT: So to prevent poke, would it be smarter to get a higher offset wheel and then add a spacer? So opt for the et30?Last edited by E30_Narek; 01-08-2017, 11:26 PM.

Yeah, the RX7 calipers are super wide. You can't grind that little nub off the side completely as it's got a fluid passage in it.
Those wheels are et40. I'm actually thinking about selling them though. Probably to some Honda guy. lol.P.O.S 1989 325is - aka Project Sh*tbox
