It's about time, gutting the Nismo suspension.

I have 2 weather knee's. I am all too familiar with that. They have changed my pain meds. I have to take it every 8hrs or I am done. So, 3 times a day, 2 times a day doesn't work too good.

Well crapola, I got the wrong length springs for the front. I got 8" 65mm and they are supposed to be 10" 65mm. I will get with Charles tomorrow and see what he thinks. I was laying out all of my stuff and attempting to change the front springs when I noticed it.

You like that, eh. Well, no as much as me. I love do-overs.

Rusty

I feel for you. LOL I'm working on the motorhome. Trying to get it ready to go on the 9th for vacation. Everything I do. Seems like I have to do it twice or go get parts and pieces every time I turn around.

The stock Rana springs are pretty darn good. If you're able can you take side by side photos or take coil measurements?

I'm running Aragosta Type S on my car and after two weeks, the fronts settled to a little less than .2" and the rears settled about .5" from my original settings. With proper height and preload, I can't imagine there's any spring bind. Still, curious to see what you come up with as well as your impressions.

Spooler

I did get in touch with Charles today. It is a learning process for both of us. Should be getting stuff ready to go tomorrow.

Do some searches on Swift springs. Lots of info on them. Here are some key highlights.

The 4 Factors that separate Swift from the rest of the spring industry:

1. Consistent spring rate throughout the stroke = more consistent performance

2. The largest amount of stroke to maximize suspension motion.

3. The highest durability against loss of spring height = excellent material memory prevents springs sag over.

4. Extremely light weight to reduce sprung weight increasing over all agility

Ape Factory

I've read all the marketing hyperbole and that's of course Swift saying that about their own product. Again, if you're able take photos of them side by side when you get the new swifts in. Would like to hear your impressions once you get them installed (compared to the Aragosta springs).

Spooler

I can tell you this. The rana springs have changed. They were 10in. at rest. They are about 2 to 4-16th's shorter now.

OptionZero

I'd be shocked if you could actually notice a difference between the Swifts and the springs that Aragosta comes with . . .

Spooler

I think that the difference would be noted over the long term. Hard to see it just by looking at it. I guess we will have to wait and see.

For sure what I feel the most important advantage from company like Swift and Hyperco. Since damper controls the spring's motion, I would like assurance of spring acting consistently through its range. Even if my bottom isn't good enough to feel the difference

Yeah mine definitely settled as well. I "think" it was almost a half inch in back but I found I hadn't rotated the bottom spring isolator all the way around so that may have caused my issue. On the front, they settled about 1/16th max. I'll double check in a week since they've only been on the car for three weeks. All springs are going to settle under weight, including the Swifts.

Besides the linearity of the spring throughout their compression and decompression stroke, one also has to look at force rate per mm of travel or how quickly they achieve their stated rate. I know Rana's using chromium steel which is cold forged and brag about their linearity as well. I'm just curious if the actual coil diameter on the swifts is any different or if there's any weight benefit.

I haven't looked into it in depth but I heard they don't make a 10kg spring for the OEM rear spring location. Is that why you went with 11k?

Spooler

Charles at Powertrix had a custom spring made by Swift for the rear. It won't fit the spring perch of the Aragosta's though. The Powertrix Swift springs are about 5mm more diameter than the Rana springs.
