sorry for getting off-topic, I just want to inform everyone
Tien already makes lots of products for the Z, including two coilover setups, one including an electronic control module that you can use to modulate the damper settings from inside the car
They also offer two lines of springs: sport and luxury
They don't offer any braces or strut bars as of yet.
Sorry again for going OT

This is a good buy folks, I recommend if you are looking at getting coilovers.
