Dear all,

Referring to the attached document, please advise what will be the most viable move given that the car is having a mileage of 80k km:
  1. replace the absorbers only
  2. replace the whole assembly and the absorbers
  3. opt out and source for sport absorbers
  4. opt out and source for coilovers disregarding all the stock assembly.
SC has been recommending to change the whole assembly and absorbers at a total cost of RM 1k which I felt that it is not worthwhile. This is because the stock suspension doesn't quite live up to its "lotus ride and handling"

It depends on what you want, but in your closing statement you already cancel out 1. and 2.
3. your spring rate may not match the sports absorbers, therefore leaving choice No:4....... :smokin:

okay. However, is it customary to change parts like top cover, bump stopper and etc when I swap in new sport absorbers?
What turns me off is that proton requires a deposit and a downtime of 3 days to replace the stock absorbers, which is absurd. Hence, I felt that it is not worthwhile in this process.

Usually those absorber cover and bump stop should have deteriorated after 80k km, better to changed them. Top mount better check, if not good condition change also...

Front top mount got a bearing in them. when its removed, u can inspect the condition of the bearing. This parts should outlast the absorber but it depends on how the vehicle is used. I have seen a broken top mount bearing which was neglected and causef warped disc brakes.

Bump stopper just needs to be inspected when removing the absorber too. If its broken then replace it. Whatever you do, i strongly suggest u replaced it in pairs.

Personal opinion :

This is an Iriz. It's not made for performance use so personally - I wouldn't bother with coilovers as it'll potentially introduce new issues from all the rattling the stiffer coilovers will cause.

What I'd do is look for a good set of sportier absorbers. For Myvis for example - the original is the stock black KYBs and they are magic carpet ride-ish and wishy washy. I changed to the RS Ultra from KYB and these are about 30-40% stiffer than stock and very noticeably stiffer but without too much comfort loss. In my old ex-Wira I went to 12k - 10k springs on my coilovers which rattled the crap out of everything but let me corner like it was on rails. A lot of things started to wear so fast after that - a lot.... but anyway the other thing I'd ask you to consider is swapping to PU bushings. Not solid PU - some compliant PU like those from Superpro. That'll tighten everything up too.

Also since everything will be out - might as well change the top mounts, bump stops, ARB links, replace them all. Otherwise you'll end up paying another amount to replace it later when it needs replacement.

Why are you changing it with Proton anyway?

U cant expect that much for Lotus Ride & Handling la. But comparing the same type of cars from comp, Proton drives so much more better.
Yea why are u changing it at Proton? U can try KYB Ultra RS, supposedly sportier damping.
550 thereabouts for a whole set. Im getting it installed soon. If u want sportier handling, 1k is too little.

My Persona at 175k, just changed all bushings, just not tie rods.

Top mount, bump stopper, and dust cover replace based on checking. If still ok then no need to change IMHO. Based on my experience usually these can last for at least 2 absorbers lifetime for stock suspension. For lowered stiffer suspension then the bump stopper often spoiled much faster.

I agree about the KYB RS Ultra, if available for your car then go for that, good value for money to upgrade your absorbers.

all the solutions that you guys suggested are good. BUT owner need to get ready to pay. All these suggestions will be more than what Proton is quoting @DNGFashion.

Lotus ride and handling does not mean track and whack the corners like LOTUS sport cars. It is still an Iris which is suppose to be a comfort family car point A to B.

If replace absorbers only with KYB RS Ultra then might be able to keep it below rm1k. (If not mistaken front & rear set is around rm700-800). But if after checking need to replace other things like top mount etc. then can reach over 1k.

I was comparing all available options which then includes Proton SC. While I agree with Izso that I am not too keen to lavish on coilovers with the same reason , there are only Excel G and IMP absorbers as aftermarket absorbers for Iriz. Have you come across KYB RS Ultra for Iriz? Besides that, I pay more attention on the mounting brackets and the bearings during this process.

I don't have the metal balls to whack corners with Iriz since it is a rather tall car. :eek:

You'll need to ask some sellers to see if they have the RS Ultra for Iriz. They have for Exora so it should be available

When there is enough cars of that model in the market, most probably they will make for it. I was surprised my Hyundai Sonata III which is based on Mitsu engine, share the same suspension as my VR.....:driver:

If no RS Ultra look for other options la. I'm sure there's something better than stock that isn't a coilover
Wonder if those manufacturer still do rebuilt on OEM absorbers? Mine was done previously but they have made them serviceable so they still honor rebuilt on mine......

My front absorbers are on their 3rd rebuilt. First round they clamp back, second round they ask to do serviceable if going to keep the car, which I did, so now in third rebuilt in 20 years. In between for a few years was using the D2 coil overs....

3 rebuilds but how often do you use the car, mileage wise in between each rebuild?

That means roughly 6-7 years per rebuild. Durability isnt bad
Yah, the front OEM set, first round rebild should be around 6 to 7 years, then 12 years, because first rebuild was when VR engine transplant, 6 to 7 years rebuild, then another 6 to 7 years later transfer to my hyundai until 2019, 3rd rebuild back to VR.
The rear original Top perfect hi lo set was used for 19 years until leak then rebuild ..... :driver:

A lot of the older ones dont have, my old saga dont have this, I not familiar with newer cars so cant comment.
Should have. Yours probably disintegrated. My VR have, My ex wira have, even my 1996 Hyundai have. Is a dust cover for the shaft....

The covers are not bellow type, and they dont cover the whole shaft, some dirt can get under it, and scratch the shaft and damage the seals, thats why absorbers fail quite frequently over here.

How many of you cover the shock absorber shaft with rubber boots like the americans. Supposedly shocks will last longer.
I did. The boots prevent dirt directly splashes on the shaft. If the dirt manage to get into the seals and damage it or scratch the shaft too badly, your shocks will leak

The cover should cover the whole shaft when its on the ground. Cannot see it when its lifted, its not enclosed as well.
My stock KYB shocks arent even leaking when I changed it few days back. Thats 8 years old, but the shaft doesn't have any force anymore. Even retreating up takes ages.

Yup, covers just slightly more than the exposed shaft. But after long time use, the cover will tear too.....
