Have a 2007 G35 Sedan
I'm looking to drop it to handle better and look a little bit better as well.
My question is what to use to maintain a good ride, smooth and not bouncy and give me good adjustability and performance

Someone recommended Tein luxury coilovers.
Was thinking about something like that, was wondering if anyone has any experience with those coilovers or something that's comparable

Anyone's input or advice would be greatly appreciated

Most seem to lean towards Eibach springs if you want an easy drop. For adjustments then you would need coilovers.

Seems like a lot of people are happy with their Eibach's. Check out Tanabe as well. Their systems offer a decent drop and a comfortable ride.

For just Springs I would go with Eibach or Tanabe!!

I just put Swift springs on my wifes car and it gave it the drop I wanted, but there was definitely a loss in luxury that I'm not happy with and I can tell she isn't as well. So I have put an order in for BC Coilovers with custom swift spring rates and rubber top mounts. Once they are installed in a couple weeks I will post up a detailed review. My thought process is if I'm going to offer these products for sale, I should have the most knowledge about it and real world experience.
