I need the assistance of some Mazda RX7 guru's as I explore the options of a diff upgrade in the MX5.
It is well know that the S4 NA Diff centre fits inside of an mx5 1.8 housing and that the S4/5 TII housing wings are the same distance (different bolt sizes thought) but I am now at the point on looking at the FD Diff. I am also looking at using the 8.8" Cobra rear end but the housings are different to Falcoonas and may proove more painfull in the long run.
I wanted to see if anybody can tell me or point me to a tech site where I can get the technical information like Shaft Lengths, Splines and hub sizes as I am seriously considering using the FD diff (beefier axles - no 1/2 shafts).
