i've read a lot of thread today, and seen you type that the tein CS, HSK RS, and others aren't fully height adjustable. whats that mean and which coilovers are? thanks

 

fully height adjustable is when you can adjust the height without losing spring compression. there will be 3 perches total on the coilover. 2 below the spring, and 1 on the shock body controlling the height at which the shock will move only.

off the top of my head, the fully height adjustable coilovers are:

Buddyclub
Top Secret
Tein Flex (get the new monotube version if you choose Flex's)
Zeal (not sure)

search for gsedanman or something like that. he has a MEAN write up.

 

Any coilover with JUST a spring collar is height adjustable. But you'll sacrafice shock travel as you go lower, not so much spring compression. your springs will always be compressed/loaded by the weight of the car - (static load).

The ones listed by jensen have adjustable shock length by adjusting the bottome bracket to the desired length. the spring adjustment should be used for preload (upwards) and not be used for height adjustments - like I said..you will sacrafice travel anywhere past the free length of the spring when, at static rest. preload is adjusted to get the desired spring firmness.

 

ok thanks, but some of that flew over my head. so "if" you were to have it on the lowest height, then buddy club would be better then, lets say HKS RS? because... the springs on the RS will be compressed and have less travel before bottoming out? am i on the right track at all?

how can you adjust height w/out losing spring compression? also what are the perches? i don't see any "perches" when i looking at pics.

chris- what do you mean JUST spring collar? what else would it have?

thanks

 

your kinda getting the right idea. but the on coilovers like the RS, the spring wont be compressed other than static compression from the weight of the car. you will continue to get the same amount of static spring compression when you lower the spring collar. again, you will lose shock/shaft/bump travel from compression the body as the car gets lowered. without enough damping, you can bottom out. you're either going to bottom out the shock or bottom out the chassis. with too much damping, you'll get a pretty hard ride. (but your car would handle great in the turns ) I'd rather hit the bump stops on the shock shaft before hitting bottom. with coilovers like herbs and mines, you can (and should) adjust the height independently from thhe spring. IMO, lowering the car even further using the preload adjustment is just for show, and likely bottom out either on the bumpstops or the chassis...whichever comes 1st. If people are going to do that just for show, they should order their coilovers with higher spring rates and matches valving to reduce the chances of bottoming out.

perches would probaby the same as the collars. you wont lose spring compression, just bump travel.

regard first quote.

 

wait, i'm starting to understand. but it your making it sound like the RS and herbs and your coilover are the same.

I"m not sure i even understand how to adjust coilovers. maybe a pic will help, these are herbs buddy clubs



so cann adjust the height with either 1 or 2? and the HKS RS is different?

 

I think section 1 is adjustment for shock/preload and your section 2 is for height adjustments. :\

 

CHEHU!

 

with the RS, you can only adjust preload (upwards to the pillow mount). I think this is what Jensen meant by the RS not being height adjustble. Looks like there isnt much room for lowering. The RS is geared more towards "Racing Sports". Guys who're more into road racing and auto-x...the HKS Hipermax II would be a one-up on these.


Here's some impressions
https://g35driver.com/forums/wheels-tires/67716-hks-rs-installed-impression.html

You could look into the Stance coilovers. They're from Japan too, if you're concerned about the JDM thing. Though, not much is known about them, they're fairly new. A lot of people one the 350Z board is raving about them about their performance on the street and on the track. And they're pretty inexpensive.

 

just look at the pic you posted. the buddyclub has 3 perches, and the hks rs doesnt.

 

ok, so when adjusting the RS to the lowest height the ride will be stiffer?
on the buddy club when adjusting the height (section 2) section 1 or the spring doesn't move with the "middle" perch? the height and shock adjustment are independent and for the RS there dependent?

 

i know one more coilover setup that has fullyy height adj..... s..... haha ha...

 

When adjusting the RS, you can probably lower the collar (perch) an inch or so (by looking at the pictures) before running out of treads. I'm not too sure on the design if it's just a performance replacement, or has a shorter overall length; much like the D-Spec for 350Z vs the D-Spec for G35 as mentioned by Gsedan35.

The 3 perches I think Jensen is calling out are in here


the Preload, Brakeline Bracket, Lower Bracket (Height Adj. bracket)

On each perch there is a locking collar, in the case of the brakline bracket, there's two (front assembly).

On your pic of the rear shock, there is only two. the Preload and the height adj. bracket. on all the shocks, you'll have to loosen up the most lowsest collar to spin the lower adj. bracket to adjust your height.

 

ok, so ONLY the lower bracket adjust the height? and the preload and the brakeline perches do what exactly? they also adjust height and the damper adjustment is on the top of the strut, right? heh.

the RS's are known to go very low, and people, well Jude, said hes never bottomed out.

i narrowed it down to the RS or Buddy Club, a lot of people say the RS are great, but i guess when you break it down to its components its not great??? can the Buddy Club go as low as the RS's?? like 2.5-3", in the back??

 

Herb, Jensen, Chris? or have i annoyed everyone to the point where everyone ignores me? heh
