first, you need to find out what the t/c rod is(because you already have them), because you keep misusing it in your questioning...so you obviosuly dont know what I was talking about.
TEIN makes nicer quality stuff in my opinion.
For starters, read the shock/damper and suspension FAQ links to articles to help you understand what all is involved with what you are under-taking. THen goto courtesy nissans web site , and see THIS diagram:

the number 2 bushing is inside the T/C rod. now you know what it is. some people call it a strut rod. That diagram listsl all bushings in the front and rear suspension peices replaceable by NISMO peices. it also will help you understand what and where things are. AS for A-arms, you have a lower A-arm in the rear of the multi-link suspension, although some people call the upper contrall arm an upper A-arm...-chet
