I'm on the fence about putting back on my gc's and buying konis but shops in my area want nothing to do with taking apart the stock housing and inserting etc... So I was wondering about getting D2's. After much looking around I found them to have better reviews than ksports in terms of the shocks not blowing.

I found a link to D2 in Australia that has a shock dyno and was wondering if they use the same shocks and materials in the USA models.

Heres the link to the D2's

Anyone else have any info on the konis or ksports? I'm not an expert on reading that dyno but is it good? lol!!! Post up more dynos if you guys have them!!!

 

It looks like D2 does manufactures their coilovers differently from country to country. Take a look...



Here's the full page of all they types of coilover they offer.

From what I've read D2 is in the same vein as K-sport, Nex, etc. as far as the quality of their coilovers...

Best bet... Koni+GCs... I don't wanna hack up my shocks and all that stuff though... so other than that, Teins are probably the best way to go.

 

1. That's not a shock dyno. A shock dyno measures damping force. The test you're looking at is for durability, and the graphs are just visual representations of different aspects of the test.

That said, D2 seems to be the only budget coilover company bragging about their performance in such a test, so it probably says something about their confidence in their product.

You don't need to see anything like this on Koni dampers. Trust me. They will most likely outlast anything else you can buy for the Maxima.


2. The third link you provided doesn't list different coilover kits. D2 only offer one kit. That page shows the different damper designs they can use in their coilover kits.


3. Koni/GC is your best bet as far as durability. If that's not your primary concern, there are a few other options that are at least on par.

 

I've been wary of both D2 and Ksport but really like that link about the remote resevoir models; that's pretty high end stuff. Suggest you find another shop willing to work with the Koni's. They're great products and the inserts are really common in the strut world. Shock dyno usually refers to the damping rate graphs and not the testing you found. Here's the Cattman/Progress Gen3 for the Maxima for instance.


And the most comprehensive strut comparison I've ever seen on the internet including both D2 and Konis

Oh God, I would pay to see these graphs for K-sports, seriously.

 

Are you talking about shock dyno graphs? If so, you'll have to buy a kit and dyno it because that's about the only way you'd find out. They won't release any shock dynos because "they're different for every application and wouldn't do much besides confuse people anyway" (paraphrased version of what I heard from them).

I think they just don't want a firm basis on which their valving can be shown to be nothing special, but that's just me.

 

YES!!! Thank you guys very much for the info! I'm gonna keep my GC kit and find a shop that can do the Konis! After reading many other forums Honda, Mazda, Nissan 240 and Sentra, Mitsubishi. They have all rated the koni GC combo to be just as good if not better that the budget coilover systems. Durability is a major concern for me so this combo sounds perfect!

 

Hell from what that article said, most of those BCTaiwan brand coilovers don't even revert back to the same settings if you go through the full range of adjustments. And from what I've learned it's good to have a square root type damping curve... basically a right facing parabola.... so you get good low speed control, but good high speed compliance as well. That describes how the Konis on my Accords felt to a tee... I had relatively soft springs (275/175 Neuspeed Sports) with Koni Yellows and I never, ever, ever bottomed out, but the ride was never harsh.

 

Entirely possible.

Digressive valving. Yes, that is best in most cases.
