Hey DE what shocks/springs do you have? What diff did you notice when you added this setup?

You're getting a real rear spring, 100% toe control and no chance of toe slip with a lock out kit.

:iagree:

And I have nothing installed at the moment, lol. But 9k rear Swifts with the midlinks ready to be installed.

My Front and rear springs are swift spec-r, do I need to replace the fronts, I don't know what spring rate those are set at, they look black like the ones in the pic?

If I know my ride setup won't get screwed up but improved I'll get these :)

Swifts r are 10k/10.5k. I liked my setup a lot. It handled well but not enough for track duty. With koni adjustables I bet it'd of been even better.

no offense, but didnt you have issues with this setup and the used 6" spring you purchased?

as it was said in the thread, you're supposed to use a 7" spring. did you buy a new 7" spring or no? if not, then shouldn't you tell people about that before they go and buy this? not trying to thread crap, because im honestly interested in buying this setup. but only if it comes with the CORRECT setup on a 7" spring.

No issues and no, spring length didn't matter. 1. I don't rally race and 2. To achieve a certain ride height you had to adjust the perch to get there. Adding a taller spring would just mean you would have to lower the perch more to again achieve the same ride height. With a 6" spring the car was perfect where the adjuster needed to be (right in the middle). After having it installed and aligned for the months i had it, everything tightened up and was good to go. Even with the suspension fully unloaded where I had it, (about a inch lower than stock) everything was tight and perfect.

On my car the setup would NOT of been perfect with a 7" spring because the adjuster would not be sitting right in the middle where is should of been. The adjuster would of been much lower to the ground. You can clearly see its perfect in my pics with the 6" spring with a ride height of about 1" lower than stock and equal to a swift spec R.

Everything you need...

So with 7" spring I'd have to have my adjuster (wherever it is) set 1" lower?

correct. if you want about an inch lower than stock or = to swift R's you dont need to touch anything with the 6" spring and where i have it set. if you installed a 7" spring you'd have to lower the perch down an inch to get back down to where the spec R's are or where i have it set for the 6" spring.

the ONLY reason to buy and install a 7" spring is if you are bottoming out the spring. but A. that isnt going to happen on a 10k spring! with the 370Z having a light rear end and B. that isnt going to happen because a Z isnt a rally car hitting 100ft jumps.

Tnx for these dood; I hope they do the job.

I wonder if I revalve my koni yellows to allow for both compression and dampening adjustements I won't have to change the suspension too much...

Sold...

next up SPL front upper control arms and rear camber arms (as suggested by DEpointfive0 aka Andrew aka (A-hole apparently!))

Got em, thanks man. Repped :)
