I just recently installed a set of 350Z Tein S Tech springs along with front and rear SPC camber kits. The install was not too difficult, but definitely took me the whole day. The drop is pretty good on the springs, and the ride is very similar to stock. I notice it is a little more harsh over small bumps, but I am very happy with the ride.

The SPC kits successfully got me back into factory alignment specs. I did not have to use the spacers that come with the front kit, or the toe bolts that come with the rear kit. So far I'm happy with the kits.

I can post some pictures of the final product later if people are interested.

I just thought I would post this since there seem to be so many questions about springs and camber kits. Let me know if you have any questions.

 

how do you know when to use the spacers for the SPC?

 

The lower you go, the more likely that you will need to add the spacers. They offer more positive camber. I would say if you're just dropping with springs you probably won't need them, but if you are really going to slam it with coilovers there is a good chance you will need them.
