You google lowering springs for 370z and swift is probably gonna be right there in the front page a few times.
Whiteline on the other hand isn't really advertised, so it makes me feel like they are a kind of hidden gem that people don't give a chance or just can't find haha. Either way the springs should be better than stock.
