Yeah, rockauto has the GR2 and Monroe sensa-trac(Both come out to $135 per set). I'll check if tokico even makes struts for the X83... MX83 was 89-92 model btw.
If it helps any with options, I can pick up front MK2 supra strut/coil spring assembly, and rear MK3 supra ones.... they bolt-in. Would that be a worth-while upgrade?
edit, 935 motorsports sells some tokico HP series(or illumina for $100 more).
I think its $245 for a set, but its unclear.
offtopic, I was thinking of picking up some Z32 wheels for it at the junk yard. They are 16x8.5, unkown offset, 5x114.3... Should work?
