my friend has done it, but using S13 struts. he just need to change to coilover, and make slight modification to castor rods. S13 castor rod can be used, just weld a new bracket one the same position. the result is, damn nice for drifting and braking.
another one i m thinking of is using R32 strut, as my another friend change his S13 to R32 5 lugs. 320mm disc
seems like several nissan and datsun strut are interchangable, just try it!
i will change it in few weeks, buy the time i tell you if possible. cheers
