is megan really 1.5 drop?

i thought the lowest was ark gt s? could someone clarify thanks..

on a side note i was thinking of lowering my 2013 z on stock rays wheels on ark gt s (if that is the lowest drop) was wondering if i would need any other parts to make my alignment perfect. also after reading these comments would like to get spacers..

Ark GT-S

I recently switched from Swift to Ark GT-S springs. I loved the Swift springs, they just didn't lower the car enough for me. The Ark GT-S springs, on the other hand, just gives the Z a more menacing stance. With that said, my car's too low that I managed to destroy the front aero diffuser, left and right air guides, as well as bend both of my FI canisters in 48 hours. My car can literally scrape on a burrito. I'm switching to coilovers.

This doesn't make sense to me...

Swift = 1.2" F - 1.0" R
Ark GT-S = 1.4" F - 1.2" R

That's less than a 1/4" difference front and rear going from Swift to Ark. That's like the thickness of an iPhone. How can only dropping that much more all of a sudden cause you to scrape everywhere and damage mufflers?

When I had my '91 Miata, I had it lowered on coilovers, 1.75" front and 1.5" rear. That car sat a lot lower than a Z on Ark springs and I didn't bottom out and scrape on stuff with it at all. The only issue I had was a little scrubbing on full lock in the front.

Not arguing, just trying to understand that post.

I get my gt-f springs put on this friday. I'll try to get a before and after pic of my base 370z since no one else did on here.

Hey guys, a have a couple questions for those that have installed lowering springs on their Nismo. I have an 09 Nismo and I love the way it rides and handles, but I want to close the tire to fender gap by about an inch, front and back without changing the ride / handling too much. So with that in mind, and based on the spring specs in “Trips” post, it seems the Eibach Pro or Tien springs would be the way to go (?) – due to the similar spring rates.
I understand that the Nismo stock ride height is about half an inch lower than base or sport models. Should I then assume that a 1” drop spring will result in a half inch drop for the Nismo due to its “pre-lowered” state(?)

Any positive or negative feedback from other Nismo owners with spring kits, ride / handling, general drivability etc would be greatly appreciated.

Just dropped my Nismo on swifts at the recommendation of trusted forum members. The drop is perfect. Zero regrets and amazing drives like stock. I also added rear camber kit and spacers all around. Now onto HFC's, intake and tune!!!

Ha!!! My pic taking completely sucks so this Sunday I have a guy coming to hook it up

FLUJOKE · 04-14-2016, 05:13 PM

I don't have a Nismo but what I do know is check and make sure they removed allllll the buffer shocks around your springs from shipping. Get under there and feel around. Just might get some free lowering. Lol also swift are the best hands down. You will scrape no matter how careful you are. Always remember that

I've had Swifts and Ark on the 370Z. Swifts are great, but certainly not the best. The best is what gives the perfect drop for the owner, considering 90% of drop spring customers don't worry about track use. If they did, they'd be getting coilovers. With that said, Swifts just don't drop the car enough. Ark GT-S on the other hand, drops it too much--for me at least. Aside from making the car scrape everywhere, Ark GT-S springs are less squeaky. Let's face it, it's easy to say a set of springs are great and comfortable when the drop is barely noticeable.

I'm just saying they're better bc u don't have to worry about scrapping on a burrito if you're on swifts.

I must admit, you're right. I wish Eibach made Sportlines for our cars though.
