Hello, after using the search feature and reading a bunch of posts i have come to the conclusion that the Tein CS coilover system is for me. Basically i am looking for comfort #1 with some performance after. However, some of the posts from the search feature were really old, dated back to 03'. Is the CS line still the best comfort/performance system i can get?

 

probably, but a little high on the spring rates for me.

 

hmm thats a pretty nice drop you have there Kenchan, basically all i want is to lower my car, maybe i should just get the S-techs? how are the ride on those? or will i need to buy the shocks also anyways, so i should just get the cs?

 

alright. so i know that the spring rates on the CS are high. but how are they compared to stock? what are the stock spring rates and what exactly is the difference between stock and the CS?

will the CS coilover system perform better than just getting aftermarket springs and shocks? or are the spring rates too high?

 

Wait a minute, were gong to toss a great system into the dust bin because we're labeling it as having spring rates that are too stiff. Look I know that I can be known for bringing up how the Flex setup and the Z33 Jic setup's are known for being harsh via spring rates and owner review's, but the CS isn't remotely in the same camp it is exactly what your looking for. And quite frankly their is a simply pickup the phone and call Tein fix if you still are worried that it's spring rates are too stiff (I'll explain below). Even so, we are talking about a setup that blends dampner settings with spring rates to offer a comfort biased ride quality. Unlike the flex setup, where it's spring rates does have a profound influence over ride quality even at the softest dampning settings a CS setup set full stiff will be hard pressed to offend, won't even offer me the what I'm looking for that matter, valving is too soft.

Tein CS (Monotube constructionad, adjustable dampners ) A comfort ride system compare to HKS LS.They are valved and sprung to fulfill their intended mission of offering up improved ride comfort. More specifically their valving will impact the performance they can deliver. And to add, revalving them is extremely expensive if you find they are too soft for you. If you want performance, pick a different Tein offering or pick a different brand.
Spring rates 392/392
Stiffer then oem by F+25% R15%
Stiffer or softer then coupes with oem 19's by F+25% R-8%

To change the above spring rates simply call TeinTein 1-562-861-9161 ask for John and tell him you need the part numbers for 336lbs springs for G35 CS coilovers, cost will be around $260 IIRC. All authorized Tein dealers can get the springs, getting them is a non-issue. The CS does have a specific dampning range that it can deal with +or- 56lbs in rate.



On non coilover option's, so many G35 spring choices are quite lame, either they curse the car with lower then oem rear spring rates, use progressive spring rates to numb the car and create at the limit behavior issues or they give you a drop amount that requires you to purchase aftermarket alignment fixes. Don't get me wrong, you can improve the car with just springs, or shocks and springs, but your not going to get close to the improvement coilovers will offer unless you artfully pick and choose carefully. You can have a very good shock and spring setup with Tokico D-specs and a good spring choice, not all springs sold for these car's make a good choice however.

 

ok Gsedan35, that post is too long, you have too much time on your hands, and yes, you are a wrenchhead. nice post but i don't completely agree.

i hate rear s-tech springs though

 

thanks. yeh, you'll want to get some D-Specs for sure. as above,
i dont like the s-tech's rear spring rates at all. i think you'll like the
Hotchikis springs. I'd do that instead..although you wont get quite the
drop I have.

my car's setup for dressup and comfort.

 

so i would still need the shocks also? i can't just buy some S-techs? Who would of thought lowering your car would be so difficult =/ all i wanna do is lower it, i dont go to the track at all =/ if i still need to buy shocks then i guess buying the CS kit would be better.

 

if you're wanting to just lower it, try the hotchikis. the s-techs alone
will make your car perform MUCH worse than stock. stay away from those.

 

cool ill look into the hotchikis spring. I've seen alot of people having the eibach prokits also, wondering if thier a comfortable ride.

 

Eibachs are great for what they are. but they lower the car quite a bit more than the s-techs and hotchikis...you'll need to get camber rods if you do the Prokits.

with the Hotchikis, you probably won't need them, springs rates are linear and very close to stock. just get an alignment and tell the tech to set the camber as positive as they can go on the rear, then set the toe within 0.10 to 0.15 degrees each side. you should be very close to stock specs.

If you want to lower the rear a tad more, you can cut the top spring mounts
(bumpstops) on the rear like how Gsedan35 did and lower the car to your preference.

 

Sorry to open this old thread again, but I have some of the same concerns as the original poster. I have a sedan that I'd like to lower slightly in order to close some of the fender gap as well as lower the center of gravity. I'd also like to maintain the OE suspension travel (I have the OE sport suspension on my 03 sedan). Therefore, I really don't want to go with just lowering springs. I also want to the ride to stay similar to it's current state, or maybe slightly stiffer. I'm assuming that this makes coilovers the only option for me. Can anyone confirm this? Also, I'd like to know how the Tein CS or other options might work with the conditions I've just mentioned. Thanks.
