I am looking for affordable coilovers (for my sedan), can anyone offer their opinion, pros/cons on the Tein Basic Coilovers? Thanks in advance...

 

My bro in law got the basic on his sedan.Ride is good, IMO its softer than the sport suspension and less bumpier than my softest setting of my Flex..

 

How low did he drop it? f/r? What are the limitations of the basic?

 

Softer then the oem sedan, huh? It uses springs that are 50% stiffer then oem, of course the Flex setup is yet again 60% stiffer then that. Limitation's on the basic are how low they drop the sedan as a minimum and they do not have adjustable dampning.

Tein Basic (twin tube construction, non adjustable dampners )
Spring rates in LBS 504/504
Stiffer then oem by F+61% R+43%
Transfers +18% roll stiffness to front

Tein Flex (twin tube construction, adjustable dampners
Full-length adjustment and height adjustment for separate setting of the height and spring preload
Spring rates in LBS 672/672
Stiffer then oem by F+114% R+98


Transfers +16% roll stiffness to front

About that ride height issue, you cannot align the sedan back to spec even if you adjust them as high as they will go, they still lower the sedan more then a inch. We have a member here that installed them on his sedan and in spite of raising them as high as he could, had to invest in front camber arms and rear camber arms and toe bolts. Even if you shop smart and buy the cheapest alignment parts you can, your looking at a extra $600. $750+$600=$1350 That puts you into other coilover systems that are better and might not need alignment parts, just a thought. HKS RS for $1410 comes to mind, though I have not confirmed min/max drop amounts for a sedan yet.

 

so, your suggestion is don't get the Tein basic?
or?
and you are saying the Flex is better than the Tein Basic?

thanks for help.

 

I just wanted to get the info out. We have seen a few good review's on the basic, but some of them cause me concern reading between the lines concerning dampning performance. The Flex has alway's struck me as unnecessarily over the top spring stiffness wise in it's current form (original version wasn't as stiff) and seeing several owners report harsh ride quality only goes with that flow. Though one can order the JDM Flex, which uses the current upper mounts and the original 560lbs spring rates, waiting 6 to 8 weeks for the boat to come from Japan is the biggest problem. I really don't find myself standing in line for either system honestly.

 

TEIN CS vs TEIN Flex vs HKS RS... which will have the least alignment issues?

@Gsedan35: check your PM box

 

gsedan35- talk to www.japanparts.com they can get your special sus kit arranged.
Ive had much success buying parts from them even for parts that are not listed at
their site. Their airshipments are very economical.

roro- that really depends on how you set the ride height. If you set it at stock
height, you'll have zero issues.

 

if we set up the stock height on Tein Basic..
how low is the DROp compare to the stock suspesnion?

thanks

 

ts- On the sedans it sounds like it's already -1" + lower on the Basics
according what gsedan35 said, so you might be better of with something like
the Flex if you want to retain stock or close to stock height.

 

whats the drop on the TEIN CS and HKS RS?

 

roro- search

 

I searched and found nothing on the HKS RS other than what Gsedan35 has posted.

 

If, and this is a big "IF", the HKS RS is the same as the JDM 350Z LS+ coilover, it will lower a sedan a minimum of 7/16" front and 1/2" rear. Max drop would be 2 1/4" front and 2 3/16".
http://www.hks-power.co.jp/products/...ssan_list.html HKS's Japan site does not list the RS coilover in any fitment, but it does list a 350Z LS+ that is NOT on the U.S. site, spring rate specs are the same as the RS specs. Remember, I could be wrong however.

The all-new Hipermax Racing Sport (RS) coilover suspension kits are the first Hipermax line to be engineered as a truly global suspension system. HKS suspension engineers’ spent over a year developing the Hipermax RS, testing on various race tracks throughout the world, auto cross events and street testing in both Japan and the United States.

The result of all this testing and development is a coilover suspension system that has been precisely valved to dramatically improve handling at a competitive track level, yet still be comfortable even on the harsh road conditions in the United States. HKS was able to achieve this versatility by using an F1 inspired single tube structure coupled with an oversized piston and dual oil and gas chambers. A shortened cylinder body allows suspension travel to be maintained when the car is lowered. The Hipermax RS also features HKS’ trademark 30-way dampening and rebound adjustability that is adjusted simultaneously for easy tuning. The included anodized aluminum upper pillowball mounts improve steering response, traction and offer a more direct feel to the driving surface.

 

Well, I never thought about them to reduce transit times, mainly because they are not in the ball game price wise. Even with the softer JDM Flex setup in the cards, I'd rather have other choices if in that price range. Could be a different story if Tein offered their Type RA coilover fitment and then with realistic spring rates.

I want Monotube, adjustable dampners, less then 504lbs spring rates and to not drop the sedan more then 1" lower then oem. Jic is out because of reliability concern's, weak rear spring rates rules out Cusco Zeal, D2, and T1R, Tein CS and HKS LS is out because of comfort bias in the dampners, Kw is out because of progressive springs. Buddy club and Kg/MM are out because of really high spring rates. This leaves me with the HKS RS and the Bilstein PSS9 (with Eibach ESS rear springs). I don't offically know how much the RS coilovers would drop a sedan, but I have confirmed that the Bilstein's will drop the sedan 1" as a min, but they are redesigning their rear spring adjustment system right now and aren't out yet.

Bilstein PSS9 coilover (Monotube construction, adjustable dampners)
Special Note: Mild spring rates, but Bilstein says the dampners are performance valved
Spring rates 370/425 (Eibach ESS linear spring purchased seperately)
Stiffer then oem by F +18% R +24% (at peak rear spring rate)
Transfers +6% roll stiffness to rear
