Nismo vs S-Tune Suspension
 

Probably going to pick up OEM upgraded suspension for my Sport Package. Sticking with OEM for N/V/H reasons. Didn't know how different the 370Z Nismo and S-Tune springs/struts were if they are different. My car is my DD and also gets track time. That said, I don't want anything to harsh that's going to rattle the interior apart.

Maybe I should just spend the $ on more tires.

Decisions
 

I am not sure you would notice much difference in the S-Tune. If you are planning to track the 370Z, I would first get tires for track use,drive it in the stock class, then look elsewhere for suspension changes.

Off-topic: Is the Morgan with the infamous wood pieces?

Parts of the frame are made of ash. Strong, light, durable I'd say more "famous" than "infamous" haha.

And yeah, I should just get out on the track more before worrying about upgrading stuff. SS lines should come beforehand anyways.

Tires will do way more than suspension.

^ I know this having a decent amount of track time, working on a good square setup now.

If it's my money and I'm paying retail for new parts, I'm buying a set of Koni's before I buy S-tune or OEM Nismo. If it's a cheap set of takeoffs, go for it.

I went from the sport/touring springs/struts, to the S-tuned springs/struts. I also added Hotchkis sway bars F/R. I haven't made it back to the track, but on the twisty roads around here, it is running better than before I changed anything. Was it the sways? Was it the stiffer springs/struts? Probably combo of the two, but I like it. It is nice and firm, but not harsh. It can cause your girlfriend to get a little jiggly if the freeway is concrete, and a little bumpy. I won't make it back to the track till April unfortunately.
