Transfer my Koni/Swift setup to Nismo?

UNKNOWN_370 · 06-28-2017, 04:56 PM

I lowered my Z sport with the above when I first got it along with the rear camber. As I'm planning out my Nismo project. I was wondering if I should replace the Nismo shock with my koni shock? Will their still be an improvement with the Koni's over the nismo? Or should I part out my Koni's and only use the swift spec R springs?

Thanks in advance for your input?

The Koni's have a shorter shaft than OEM correct? Aren't they designed to work with lowering springs? The Swifts might keep the OEM shocks out of their optimal range and they'll wear out more quickly.

Lastly, how many miles on the Konis? If they're high mileage, might be good to get them rebuilt first.

What is the mileage on your Koni's? If you got some mileage on them. Either rebuild or replace. The new Nismo's have softer valving and springs I believe. I would drive the Nismo for awhile to see how you like the ride before pulling the trigger to quick on changing stuff out.

I have about 25,000 miles on the Koni. I thought the Nismo shocks were half an inch shorter so I wasn't sure?

I gotta lower the car a little for sure. My Koni swift combo definitely improved handling and made the car a little smoother on road. I'm just wondering what nismo owners think about where my brain is going with using the same suspension setup in my sport.

The Koni/Swift combo is a good set-up. I wouldn't worry about it.

If i remember correctly don't Koni Yellows have life time warranty? IE you can send them in for rebuilds whenever you want?

Both shocks for the Nismo and base have the same design and internals. The springs and bumpstops are what differentiates the two.

Not sure changing your Koni's with that amount of mileage is necessary, but sense you are taking them off/took them off your previous car, if you could get Koni to exchange them for free, sounds like a good deal. Putting them on the new car sounds like a logical upgrade.

Thought Nissan changed the valving and spring rate starting in 2015?

It's possible. The versions i measured with JIC was the 2013 base and the 2011 Nismo.

Both internals are the same. I haven't measured post 2015 versions. In either case i highly doubt the valving has been changed. I've driven both the 2016 and 2014 Nismo models and the suspension feel is indiscernible to me at normal road speeds. Apart from the seats being the noticeable difference.

How did you measure the shocks? With a shock dyno?

Yes, among several other measurements. I may put in another effort to find a set 15-17 Nismo and base variants to test. I wouldn't be surprised if those aren't that different either though, the weight of the vehicle is well within 100Ibs of the 09-14 models.

You will probably like it better than the stock Nismo setup. Stock leaves something to be desired on bumpy roads. Aka, missing a kidney.

Fixed it!

If you have a heavy chested woman in a tube top in the passenger seat. You don't know what you are missing.

bump and rebound technically could be measured in displacements of tits/mm or /in depending how large your cup volume is.
