Topic: Shock absorber

[Fusion]

Just wondering whether you guys change rear shock absorber after putting all ICE equipments behind the boot? 

[GRexer]

Hm... it's most probably the need to change to a stiffer rate spring for the rear absorbers instead. You'll probably need to find those "heavy duty" springs. The reason behind this is due to the increase in weight in the back hence you'll need springs with a higher spring rate so that it'll take more weight to reduce the spring's length(as compared to 3kg/mm and 5kg/mm, it means the first spring takes 3kg to reduce length by 1mm and the second spring takes 5kg to reduce length by 1mm, of course, stock rates ain't that high, that's for an example only)

If you are driving a Wira, the Waja's stock rear springs are good to be used to increase the height of the rear of the car.

But by doing so, there's also the possibility that the rear absorbers won't last as long as it initially would, like the saying goes, you'll always need to have a matching spring and shock combo. ;D

  change spring only nia? I know nuts about car absorber and spring. My wife's relative saw my car sagged, concerned the load I carried behind my boot and back seat on my way back to KL from Penang.

[GRexer]

Well... it's actually springs that hold the weight, absorbers are to "destabilize" the springs from the upward and downwards motion(hence it's name, absorbers), so... it's actually springs that should be change if you are looking to increase the rear height, definitely with the means of a taller spring, or a spring with a stiffer rate.

I'm pretty sure llsaw can give a good comment on this issue.

as for my setup previously, due to my heavy MDF board, amps, batteries, power conditioners, cables, sound proof, etc ...

had to change to adjustable springs (hi-lo kit) and also adjustable sports absorbers from koni ...

it has been almost 2 years plus since this absorb + spring setup is in place until today...

for me, springs actually denotes the height of the car when it is stationary whilst the absorbers determines the ride's (hard/soft) rebound rate... cheers..

The cheapers solution 1 .. hee hee..  put on top & bottom absorber bush.. cost maybe around RM25-35

[fooyc]

1. Remove the same amount of weight to whatever you put into the car. 

2. If you load your rear/trunk, try to take out the spare wheel, they can weigh quite a fair bit.

3. If you are hardcore enough, corner weigh the car before you can decide on damping rate/spring rate

4. Otherwise, slap on a stiffer spring & firmer damping damper. Most stock dampers can't last well with additional load.

& all the luck you need.

what happen when the bush koyak?

imo, like grexer said... replace spring
would be best.

[Newton]

My vote would be replacing the springs to harder one's, OEM springs is more on the comfort side so it tend to be on the soft side. If possible replace your existing bush also since you're changing springs. One time "Kao Tim"...If bush koyak then u will hear sounds like "Kruk Kruk...Tuk Tuk or Tong Tong" which it really irritates me...

[Fusion]

  thanks guys for sharing your views. Very informative. Any brand of spring I can shop for  ?

[Newton]

What car are you driving bro?

[Fusion]

Duh...sorry I didn't mentioned b4. It's wira 1.5GL

[Newton]

Wira always got that problem one le...:( Go look for Eibach springs or Tein springs...

[GRexer]

Newton, think it's not so recommended to get those springs you mentioned, later lagi lowered la the car ;D I think what built meant by the bush koyak thing is what OSB recommended, you won't exactly hear sound from that, the spring would have actually came out from the assembly especially if the top mount's bush is too thick!

Anyway... i'm not too sure what brands to recommend, but most people have good experience with increasing the rear height of Wira by using the rear springs from Waja.

Waja one also can? Cool...Tried using Eibach for my Wira Aeroback last time. It solve the problem that Fusion had and of course. The car also looks sportier but the backside not saggy already.

Hmmm...the sound i type is just my expression...:P I can be wrong la, because when it happen to my ride i went to the mechanic and he check then he show me the condition of my busy...Ishhhh...Koyak liao. I'm no one to say anything le, better go to the workshop let them check...:)

Grexer, how's the Blade amp going? When can audit...;)

[GRexer]

The bushings problem you mentioned is probably those lower arm, steering bushing type i guess, this bushing that OSB mentioned is the upper spring "rubber"

Yeah.. Waja's springs can be used if wanna retain more or less stock height(after loading)

The Blade's i've tried, but so far haven't got time to go Mike's place to try, either he's busy, or i am. ;D

[Fusion]

Ooo.. so waja one can use lar... noted noted 

[netken]

The cheapers solution 1 .. hee hee..  put on top & bottom absorber bush.. cost maybe around RM25-35

agreed ... this would push up the height and also make the ride less bumpy .... but it will not solve any problem permanently esp. when driving and masuk big pot hole ...

rubber bush most commonly used are Mercedes Benz rubber .... can be used in avanza also... for example .... but certain mods must be done accordingly ... not too sure on wira yah ....

eibach will prolly lower ur car, its termed as progressive spring ... many ppl make the wrong move by having eibach springs i.e. lowering ur car ... but with stock or normal abs, hence nice to look at, but the ride is damn hard and sure to hit the firewall ... lowered sports spring must pair with sport stroke abs ... or less the stock / normal abs will koyak overtime also with the eibach / lowered springs ...

[GRexer]

Actually, i think that most European coils are still pretty good to be paired with the stock shocks, as that's what they are meant to be used with, except some exceptions like certain H&R and Eibach Sportlines.

The Eibach ProKit is still ok enough to pair with stock shockers.

[Bert]

To resolve any issues... get a set of coilovers.. adjust the height to what you need and you are done... stock looking car

[GRexer]

But well... that's actually a good idea, but the problem with getting coilovers, is that 1) it's usually expensive 2) if it's of the cheaper type, it's usually locally made 3) coilovers usually are stiffer than stock unless you can get custom valved units, but then again, it'll be costly.

[netken]

not too sure about local or japanese cars, perhaps their stock shocks are way stronger, as in conti cars that i have come across, the lowered sport springs are only nice to see .... terrible in rides. to have a balance setup, it is always advisable to match it appropriately with a sport abs...

i wouldn't dare say that all sports or lowered springs are made to work with stock abs, it all depends on the models of the manufacturers ... and also setup / specs provided ...

eiback prokit, i.e. the red packaging one comes with springs, and also springs + abs package, can compare the stock abs with the abs that comes packaged with it and definitely there will be a difference, just that sometimes i wonder how come they sell the springs separately, perhaps a different model .... 

either way its a mix and match, sometimes trial and error process unless the setup has been experimented by some other ppl .... 

[GRexer]

Yea.. that's true, but so far i find that the Eibach/Apex + Koni setup has the best balance for road usage on most of the car models they provide :)


*Yippie! My 200th post!*

i agree with that combi too .... Koni is actually not bad.... bundled with Eibach .... 

[Bert]

Umm... what is wrong with local coilovers? And it isnt that expensive as well.

For the price of Eibach springs (RM800) and lets say uprated absorbers (all 4, Waja, 1000+) You can get the rear coilovers and change the front shocks

[Oldskolboyz]

The bush wont koyak easily 1, even local made coz the rubber very thick around 2cm.. this just 1 of option to make your car higher.. there have afew option & depend on your pocket also, how much your are willing to spend..

1) as I said earlier
2) use Waja coil spring, U need to sacrifice comfort
3) use eibach spring & Sach absorber, coz Sach absorber c/w short strut
3) use DA6 absorber + spring, sangat cantik.. if can get Tokico lagiiiiiii cantik
4) use DA7 absorber + spring, to high & Rally look like
5) use SV4 absorber + spring, to hard but best when layan corner
6) Koni/Tein absorber set (non adjustable)
7) Adjustable absorber, dont use High/Low 1 coz usualy this type for street race.. the best use Hi/Low/Soft/hard type

To avoid kruk krek kruk krek sound came from spring, use water hose on top & bottom spring 

 

[17Ters]

I have only one thing to say. Stiffer springs + amps =! 

Why? The allen keys bolts on my amps are coming out... Iam using 60 series tyres and Eibach... Sakit.. Have to tighten them every week... 

Iam thinking of adding some shock absorbent material so the amp seems to be floating...

...but the backside not saggy already...

backside not saggy only look nice ma...
