Wanting to lower an 06 Grand Touring and not have to replace stock struts or purchase camber kits. Is this possible? I am putting on a body kit and feel the car needs some lowering to make it look right but i don't want to scarifice handling. Daily driver with some occaisional spirited driving. I have been directed toward these springs. Does anyone have experience with this type of setup?

The amount of owners that drop .8" or less that are able to stay within oem alignment specs without aftermarket correction is far higher then those that drop 1". Though that is not to say you won't need rear camber arms and elongated toe cam bolts at the very least. Tire and wheel choice can effect the outcome. Keeping the oem shocks with the spring choices you mention is a total non issue, wear wise and control wise. IMO, since your have a 06, I would go with the RSR springs because of the rates vs the Swift springs.

Your stock spring rates are,..
314/427

RSR 350Z linear springs .6”/.6” (Ti spec is the same)
Spring rates in LBS 345/417

Swift 350Z linear springs .8”/.6” drop
Spring rates in LBS 336/364

Another choice to consider

Cobb Tuning 350Z Linear springs .75"/.9" drop
Spring rates F345/R438

I like the numbers for the Cobb springs better but have read a bit about potential fitment issues. Some of the post I have found are fairly old so I'm not sure if these potential problems still exist. I have also considered the Nismo S tune coilovers. But have not read about many folks having these, so not a lot of feedback available.
