Im interested in purchasing either or of these systems in the future. However, Im not sure what other suspension mods I might need with these setups. I have heard you need sways for the Tein CS. My cousin installed the HKS LS+ on this 350Z and he said the ride is awesome and way better than stock. Im looking to keep most of the stock comfort but for the car to feel more planted to the road, better handling, agressive look and what not. Ive heard a lot of good things about the HKS coilovers so Im leaning more towards that. What do you guys think? Any help or suggestions would be greatly appreciated. Im pretty much a daily driver too.

 

Anyone?

 

You don't NEED sways with any of them. Both coilovers were designed to be used with stock components but also incorperate aftermarket parts aswell. Its your choice to change the sways or not.

I've heard many, many good things about the HKS coilovers. Though I have never driven/riden on them myself. Tein CS is a very comfortable coilover. All the comforts of stock, but better road feel. The thing I really like about Tein, is having the EDFC.

As an installer, I've installed dozens of Tein coilovers, but never any others. The rear coilovers are enclosed inside a strut housing in the trunk. The tops are not exposed. The EDFC allows you to put a motor on top of the coilover and run a wire out. Then you adjust the daming force using the EDFC. If the HKS coilovers adjustment **** is on top, I don't see how you adjust the damping force without taking the strut out. So you have to set it once during install, and thats it.

 

hmmm...very good to know. thats so much for that advice. yah i like the HKS LS but the fact that the Tein CS does have the EDFC is more enticing. Ive always wondering if it was hard to adjust the dampening if you dont have EDFC. My old car was easy just pop the hood and tune and the rear same thing but the G35, nothing is exposed so makes it harder and I dont wanna tare stuff apart. So Tein CS might be the better choice for me. Thanks Greddystego

 

so will you be getting the CS?...cuz I'm also debating on getting CS or not....look forward to your review....

 

Besides sways with either of these setups, are camber kits of some sort needed for the rears and/or fronts?

 

id imagine a camber kit is needed for front and toes for the rear but all depends on the drop. anyone know the range of the drop for the tein cs?

 

Tein CS and FLEX both come with pillow ball mounts. I believe they offer camber adjustments for the front. So you may be able to get away with just a rear camber arm. But it all depends on your drop. You might not need any at all.

The drop range for Tein CS is +0.4 ~ -2.1, front; and +0.4 ~ -1.0, rear.

 

sweet! how about the HKS LS? Im prob going to tein cs anyways but just want to know about the HKS.

 

I just installed HKS LS+ about three weeks ago. I had stock sports suspension. I lowered only about .75 inch more than stock. I don't know much about the Teins, but i can tell you from first hand experience that the LS+ made a huge difference over stock sports sus. Spring rates are a little stiffer than stock, but my car feels like it rides on rails now. Def feels planted to the ground, and much more confidence on the highways, including mountain roads.

I installed stillen sway bars as well. IMHO you need swaybars no matter what.

 

Here is the thread i posted a bunch of pics. I do have a few pics of the sways n LS+......

HKS LS+ coilovers vs Tein CS are not really that close in terms of how they will feel once installed. It's not so much that the spring rate specs are different, but that the LS+ are valved to much higher specs in terms of overall stiffness. Whereas the CS setup very much toes the line of being setup for comfort. So for the person that say's I want oem softness, the CS is the way to go. For the person that say's I want a more sporting feel where I can dial in even more stiffness, the LS+ would be a better choice. Where I'm comming from is based on actually looking at valving specs posted on HKS's Japaneese web site.

HKS's coilover product that is in in line with Tein's CS is the LS coilover. At which point I'll point out that the CS has adjustable dampning.

 

Maybe a better comparison would be FLEX? Or Super Drift which has yet to be released.

 

I'm inclined to say that the Flex actually goes beyond the LS+ courtesy of it's much higher spring rates. I've never ever seen owner comment's about ride quality like we've seen from some Flex owners. Super Drift is a unknown (though I've seen then on Tein's spec pages for some time now).
