Best Riding Performance Suspension
 

I'd like to get inputs on the best riding performance suspension, as the title implies. I want a suspension system that can handle the likes of US.129 but then be as comfortable, or close to, the stock suspension. I have no preference of air ride versus coil over and lets stay under the realm of $4-5k. I don't have deep pockets but I'm not hurting either and I'm just researching my options for now.

Probably not "the best", but I'm very happy with my Powertrix street coilovers with Swift spring upgrade. Better than stock in performance and comfort. And 1/3 of the budget you listed.

After talking with Charles the other day these are one that is highly in my list. I'm still a bit worried about the high spring rate but he assures me they ride smoother than oem sport suspension. You say it's more comfortable than the oem but I see you have a nismo so that's one harsh suspension to compare to.

Which ones are high on your list? The ones mentioned above I'm assuming?

Yea the powertrix is on the list of options and talking to Charles has almost swayed me over. I think I've narrowed down to these, rsr, hks and maybe kw also maybe fortune but I don't think they go high enough.

I'm a fan of MCA. Ride is very comfortable for coilovers yet valved well enough to do some very spirited driving and hang with other high end suspension setups. I would suggest at least the X-Series or Reds, but if you're up for it, golds are to put it simply, absolutely breathtaking.

I've seen the mca and they sound great too but I'm unfortunately not brace enough for a true type coilover in the rear.

So I don't want to hijack the ops thread. One thing you left off op is if ride height is critical to you and what height you wish to keep. Myself I do not want to got any more than roughly .6-.8 so that limits a lot of options. If I remember right I looked at fortune before but just like BC their max height is still about 1.5 inch drop. Currently I am double checking that because if they can do oem then that's another to seriously consider as they have custom spring rates, custom damper rates and assembles right here in USA, otherwise I think I've. Arrived down to powertrix or rsr depending on how I feel about the spring rates.

I love my Fortune Auto's and they are set 1/2" below stock hieght.

Oh really? Well then that sounds promising. I thought I saw somewhere they were shorter length like some of the others, but if your at .5 then that sounds great. What spring rates did you go with and how is ride comfort?

The standard rates are fine for street. I initially went with Swift springs 11k front 8k rear. I recently switched them out for 13k front and 10k rear because I started tracking the car.

Cool 8k is same as OEM so that should be fine. Your new rates are close to powertrix rates at 12/11 how are your new rates on the street? I think ill give fortune a call tomorrow and see what they have to say. How were the default rates in terms of car balance? OEM is 7.5/8.1 so 11/8 would have more understeer wouldn't they

^ the track guys state to use a big front sway bar. A big bar basically increase the spring rate. So based on that, I think in our cars, the higher spring rate would be helping.

Just installed Flex Z suspension, so far the car ride quality is good. little stiffer than OEM but feels good to me.

You know the forum is dead when 15 guys didn't say KW V3s.

But yeah. KW V3s

Lol. No one is speaking up.

Ax you still like the powertrix? I read your review a while ago and sounds really nice. I think I'm down to fortune or powertrix just need to decide if I want linear or digressive damping. I've read in some cases linear can feel smoother because if the less low speed damping so for some of my freeways that have a lot of ripple bumps that may not have enough force to open the digressive circuit it may feel smoother.

My set up is on the stiff side of things as I have a Hotchkiss front bar, SPL everything and a 4 point roll bar lol! I like a stiffer set than most as I don't consider the stock Nismo suspension as to stiff. The damping is the big deal along with the spring rates. I think the 11/8 setup is perfectly fine for highway and spirited driving but really like my current set up over the standard spring rates.

Do you still have some bnew KW v3 lying around your garage for sale?

Well talked to fortune and they still believe their setup is at least a 1 inch drop minimum. I like the sound of everything else about their product just wish they had more range.

I'm running KW V1 and they're adequate entry-level coils. Nothing to write home about though.

Lol, I can respect that as every vehicle is a little different and from a business stand point I would also error on the side of caution.

You has link? Meesa gonna reads its...

edit: NVM, founds its.

If I had to do it again I would go with Powertrix. Just sayin.

Take a look at the Aragosta Type E or Type S (Type S is firmer). Both can do stock (or even a bit above) ride height as well as going way low. I have the Type S and they're firm but not harsh. They seem to take the sharp edges off of bumps but on the really rough stuff they'll throw you around on medium settings. For back road stuff, they're just brilliant. I've zero need for sway bars with the higher spring rates.

You are able to order them directly from Japan and the import duty varies by state. I paid a measly $60 import duty on mine and two weeks to my door. Just PM me if you want more details on where to acquire them. You can get them from a certain performance shop here in the states but they'll be a full grand more dear going that route.

I've had my set going on three years now and really like it. It has been reliable and really like how the car drives. My set up is for street and not for tracking. I'm sure I'd want it stiffer if I were to track her. PT had a set for that. I've also come across with Charles numerous times since the install and he has been a pleasure to speak with. One of the reasons I decided to go with PT. If I have questions, he would respond right away.

Cool, well I only occasional track so street is more important. So I broke down and took advantage of the powertrix Halloween sale. Really hoping this is nice on the street.

I looked at the aragosta before and they did sound nice but pretty pricey and without being tuned for US roads it's a bit risky. I think a lot of the JDM stuff had complaints of being harsh until they started making US offices (tien I think is one of them)

A good choice, I have heard a lot of good things about them. I went with Auto Fortune because of their reviews and a Black Friday special or I would have gone with Powertrix...because my brother Axmea? said do!

Lol well if fortune were more certain of their ride height I was very tempted with them because of the digressive valving and 11/8 sounds less scary than 12/11 for street. I figure worst case if I put it on and find it too firm I'll just try to sell it, but Charles was pretty certain that it is a smoother ride than oem so x my fingers.

That's why I recommended the E-spec dampers. Honestly, the S-specs are just fine on the road. We have some pretty gnarly roads here and I've not really found worse except in Michigan, LOL. My daily commute has a few rough patches and it's my own little Nurburgring with a bit of everything, from billboard smooth to seriously rough. On the moderately patchy and smooth roads they're brilliant, really good. I'd imagine the Type E's damping would be far better suited for the road. The Type S is listed as being for the track.

I'd really like to compare them to say the Powertrix or similar just for sh*ts and giggles. This is my second set of Aragostas, used them on another car. If you've ridden on say an Ohlins-equipped car, they feel the same. Just something about the way they dampen the rough edges. I tried to get mine on a shock dyno but he didn't have the right fixtures to mount it to the Roehrig. Would have cost me $300 to have him make a set.

This is why I bought my Aragostas, hope your are right.

Hi guys not hijacking this thread but I have one question about coilovers.
Is it normal to hear some squicking rubber sound or metal clunking sound when you running in a slow speed in an angular way going up the ramp or clearing speed bumps one wheel at a time to avoid scrapping your front chin or skirts. Lol

Mostly on a ramp going up in an angular way, dont know if I said it right. Thanks

Small noises usually come from improper torque specs on the bolts or going too low and binding swaybar end links. Can also be improper preload on the springs and they're moving around wen fully uncompressed. Also make sure there are either rubber or plastic isolatorsnbetween all metal parts. What brand of coilover? Solid pillow uppers or rubber mount?

Which set did you end up getting and from where?

They are new/used... LOL

Rubber mounts. I figure my preload is not quite accurate. I'll check on them.
I use ISC coils.
When running fast even on curves the suspesion holds well no noise heard.
Thanks for the info.

Well already ordered my powertrix and with the overwhelming positive reviews I think I'll be ok, just have to hope I can take the spring rates.

Question for those that have done the install, are the rear springs fully relaxed once if the ground or do you need to slowly lower the arm with a jack or pole jack? If needing to slowly lower the arm can it be done with just usual jack height of car (meaning there is enough swing room of the arm to get the spring out before hitting the concrete).

You did good. If I had to do it all over again I would get the Powertrix.

My current stance after rasing her up 1.5 inches!http://uploads.tapatalk-cdn.com/2016...96abbd0da0.jpg
