Nice ride Tom, loving the care you've put into your beemer. What engine is it running on? m50?
thanks ak.101ss, it's a life long hobby thing, just adding stuff to it from time to time and basic upkeeping, not an M50 but an ancient M70.

any for vw golf gti mk6?
any for suvs'?
Hi there, how much would it cost for silvia s15? Thanks
hi just wonder if there's support for toyota seg and how much would it cost..?
guys, if Nanda don't answer you quick enough here, it would be best if you could send your questions directly to RCS. they'd be able to give you a detailed answer

Oh my god, a 5.0 v12 in a e34? That's what I call THE Ultimate Driving Machine. How'd you get it in? Bet it takes off like a rocket. :adore: :adore:

a very good question there, and the answer is no, not all are velocity sensitive sir

In theory damper is suppose to be velocity sensitive, but in real world, a lot of factor comes into play. Like used for what application, the design of the main piston, costing, etc...

Hi again, I'm sorry for not responding earlier. Like I said earlier, please drop me a line to discuss what you would like for your car.

Cheers again

I'm sorry, but aren't ALL suspensions sensitive to velocity???

Good question Midship, and yes, all dampers are 'velocity sensitive' ie damping force is proportionate to velocity ie piston rod speed.

With conventional dampers, the damping force is directly proportional to the velocity, ie the higher the velocity, the higher the damping force & if you plot a Force-Velocity graph, it is linear.

different applications saw this curve being manipulated to produce digressive or progressive curves.

'Velocity sensitive' is a label generically used to distinguish a certain type of commercially available damping force curve.( just like linear, progressive or digressive)

Another way to simplify this curve is to say that it has progressive, digressive and linear sections in the same curve.

What it is, is a mechanical system tuned to give you comfort and traction but firms up when you turn into a corner, allows the wheel to move up fast when you hit a bump or drop down when you hit a pot hole, take jumps at high speed, etc etc etc.

So by being able to tailor the force curve or isolate the various points in the curve, it becomes 'velocity sensitive' instead of having a fixed type of curve that is either linear, progressive or digressive.

Cheers

Nanda

red_cloud/Mr. Nanda,

With all the technology, knowledge and theory,
Are there any possibilities with your expertise to refurbish other brand of suspension?
Thinking to use your product in future if refurbish my existing are wasting time.

Thanks in advance.

Hola!
Nice review Tom.

Nanda,
I wish u can put Honda FRV/Edix into your consideration too.
This rare Honda's mini mpv do seriously need attention -

err...i know a lot of edix/frv owners out there still searching for an aftermarket
suspension set up for their rides.

As for me, I will start saving bro...iskk!!

p/s:- one good review, i really appreciate to know that Nanda and his team exist in Malaysia...yeayy!!

We do re-build certain dampers which we have the parts for. But these are mostly servicable dampers like, proflex, ohlins DFVs, some bilsteins, drummonds etc.

and we haven't done any Edix's yet, but customizing a set shouldn't be a problem

so let me see if i understand this. i am not a suspension expert but i know what i feel when i drive the car and i'm sensitive to that.

with this system, i have the best of both words - comfort + improved traction without having to suffer from bone jarring rides of firm suspension setups. is that correct?

only issue now is comfort and stiff means different things to different people..

droll: you can specify the sort of feel you want, say a known car model you've recently tested to help them help you

g4i8y0t: yes they must

Firstly congrats to yet another homegrown full on talent backed with r & d. Up to this point i was giving up hope thinking such breed of ppl exsist no more in bolehland. Perhaps its also a wake up call for everyone else to start having more research backed into the products they sell. Its all well and fine to judge a product based on price alone but living in malaysia, we know that the price often does not rack up to the quality.

Interesting too to see aragostas and the exquisite rana springs ditched for RCS. The point to note here is that everything bought from japan does not work well on malaysian roads. In the case of absorber valving, i have only found 1 which can stand up to the harsh brutal malaysian roads. And pls stop kidding ourselves with national pride saying our roads are good. They are quite simply not. With potholes and gaps and uneven surfaces. A shock absorber has to be built and valved properly for what its about to encounter. Springs also matter, with most of the jap manufacturers offering 'out-of-the-box' rates in excess of 5kg-mm...its never going to work for a road car. Hopefully ppl can be realistic about what they are putting their tyres on. Give local TALENT a fair chance. They deserve it.

Hi to all driver of Proton Persona,

My purpose to open this topic of discussion is to get the feedback or an opinion or solution from the new Proton Persona Elegance that had been launched recently in Mac 2010. The reason is I just bought my own Persona Elegance for a month period but there have been several problem occured or more precisely, after one problem solved there will be another mess occured. Not my intention to downgrade Proton but in term of payment... I have to commit for 9...
