Matching sports spring with stock absorbers ...appreciate feedback

[SlipStream]

Was wondering if anyone tried fitting sports spring to their car's stock absorbers? Did a low level/budget upgrade by fitting in a APM performax sports spring to the stock APM absorber of my wira. Despite the drastic increase in bumpiness (think it's called road-feel here :_: ), I was pretty satisfied with the performance of the upgrade. The problem crops up after a few weeks when i started hearing weird pinging sounds from the rear and back portion of the suspension..both at the right side. The sounds are audible in normally driving... dun even hafta go through bumpy roads to reproduce. Simple actions like accelerating or braking are suffiicient for me to reproduce the sounds. I have sent the car for inspection but to date, the cause of the problem remains unsolved.

Anyone, has encountered similiar problem before? I was told by a friend that the problem could be caused by a mismatch between the spirng and the absorber, i.e. the spring needs to be longer than the absorber for the suspension to work properly?

Feedback appreciated :cry_smile:

pinging sound??.... how geh??... can explain more detail??..

try bounce ur car and check if the absorber is damaged already or not...

my car also got lots of sound after installing sport springs.... mostly due to screeching sound "eiiik eiik" at the suspension joints...

The sounds goes like "tok tok" ...i think it can be more accurately categorized as knocking than pinging. I get those from the front right suspension. Some of those "eiik eiik" kinda sounds as well...from the back suspension. These sounds could not be reproduced by bouncing the car up and down... been doing that the whole afternoon at the workshop. The mechanics are at a loss too. The absorbers are quite new..confirmed not damaged, so are the arms and suspension mounting. Headache.. headache :cry_smile:

is the wheel scratching against ur suspension links??... other than that, i also not sure la...

did your mech insert the springs correctly?

are all the nut screwed properly?

ur abs, long or short stroke?

I don't think so since the mechs replaced the shock absorbers and inserted tubings around the springs... the sounds still came back.. I guess the next best thing is to leave the car at the workshop for a few days for the mechs to troubleshoot the problem. Then again, it's always better if i have a rough idea on where the problem lies..at least would not end up kena 'pancung' :confused_smile:

The absorber was taken out and reinserted again a few times during the inspection at the workshop. So i think can assume the nuts are fastened properly. The car uses the stock OEM APM absorbers that comes with all Wiras...so i assume it's a long stroke? The absorbers are new though..replaced it 2 months ago...so don't think so they would be the cause of the sounds. I didn't know absorbers can be categorized into long and short.

what car you driving??

I got it from a workshop here in Penang. Think it's quite common to see it lying around tyre service centres around here. If i'm not mistaken, it costs around RM300+.

what car you driving??

Not sure if you are directing the question to me.. it's a wira
