i don't understand what you guys wrote..

like TS, I running on 8k 4k rear..
eibach oversize anti roll bar..
wide tyre with japan rim..
softest setting
spent unnecessary money on driveshaft and lower arms until I don't even bother to look at them.


conclusion:
I give up..
less than 80km, its still comfortable.. at least, self deceive..
more than 140km, come dance with me in the car.
hence, not many want to sit in my car..
I will wait for the day for the coilover to be 'kong' before I go back to stock...
old man's bones can't take much of the rocking nowadays..

*p.s: if anyone want to donate a 5k spring, I will love you to bits

Bro kurt, yup that 140km feels. Very agree.
I use hwl st1 for one year. 8k/4k. After collect comments from friends, few pomen.
Never cross my mind to replace 8k to 6k spring. Which i sold whole set for 700.
Luckily can sell it.
Do my homework finally decide ftuned 6k/4k.

I din say HWL not good. Not suitable for my wira setup. Other wira, maybe OK kut.
Just cant get it right no matter how patient i am. The nearest Fr 8 clicks, rear 10 clicks from soft. Drivable but handling still bad at speed or cornering on bumpy/wavy road. The uncertain feeling scare me yet teach me how to control car.
The feel of car jumping, and duno where the steering response. For wira, 8k front spring is too hard.
Check steering rack, joint...etc. All OK.
Flat road very nice. :driver: since Balik pulau newly tarred, syok lah.

Is up to TS car and butt. Maybe 8k spring good for persona.?

My persona mostly I alone drive so for me so far 8k/4k setup wasn't that bad yet. Plus using it for college only mostly and 80-90% highway use only. At first read few forums and got scared chassis will crack with hard springs then decided to throw in front and rear strut bars to reduce the tension at each tower (or to transfer sikit the load to other side). Still trying few different combination of damper settings. Lets see how. Hahahaha. If no swap 6/4 or all around 5k

Maybe because persona is slightly heavier by few puluh kg i think so a bit better. But still can feel the throw at highspeed :biggrin::biggrin:

But what I am surprise is most of the myvis using 6/4 on their coilovers and the car weighs less then 1000kg

If your car is low, you won't feel the throw that much. Lower center of gravity. Braking also improves some what. Downside is difficulty in getting out of car & the glare of other vehicle's headlights.

Then again, to get really lowered, you will require stiff springs. High speed travel may be a bit jumpy.

To simplify, if you dont need it that lowered, you dont need springs that stiff

Actually with stiffer springs, if you carry more weight (passengers) the ride is better. This happens to my VR. If alone very bumpy, but with 4 to 5 passengers the ride pretty good.....lol:rofl:

My car is kinda low. For previous persona with 195/55/15 front has around less then 1 finger gap and rear has 1 finger. So even with this spring rate maximum I can bring 1 passenger including driver. Or else tyre rub at the back. Hehehe

I got experience with hwl st-1, spring rate front 8k. Just too hard for normal street drive. Since my wira is light.
Been gone through damper tuning myself, one click by one click....
Yet, cant drive over 130kph. Very bouncy. My bone, butt can handle but safety is at risk. Bridge joint, toll bumps...etc just bone breaking for my mom but my son enjoy it.
6k front /4k rear is just nice. Reminder, don hope stock comfort on coilovers. We want is control, drivability.

Like izso mention, handling got many parts inter-related.
Coilovers, macam macam bar , rims, tyre, car weight...etc

Even before i jump to ftuned, dealer ask me msg Farouk.
Explanation from farouk about same as izso.
wakakakak I feel you bro when I was on my adjustable with spring rate 5KG front and 4KG back and 26 clicks front and 11 clicks on the back. The front passenger is still manage to accept the response from the road but for the rear passenger, they will complain after 10min ride. This make me phobia of ferry friends or colleagues out. They will start complain like my car pass over those bump (road repair) or yellow line (especially those toll with thich yellow line).

actually quite embarrassing with such setup while people sitting in your car, commenting why the whole setup is horrible.

and somehow, you got to educate them.. telling the beauty of this setup..

but, hack them. you only live once, live it to the max :proud:

Damper setting is tricky loh.:banghead:
Set full hard is feel of jumping everywhere = like no suspension. Too hard, too soft also depend on driver butt.
Passenger butts is secondary. Agree to bro kurt_629.
Important is apply the setting at wavy, bumpy, here potholes there potholes road. Then will know how good the car handle straight at speed and corner.
Safety 1st. :driver:

If it's low already, then changing to lower spring rates may cause more scrub. Another factor for your consideration.

I think his is full adjustable, so should have body shift. Softer springs, body shift higher loh.....

What do you drive? Perhaps you need thicker tyre profile to offset for comfort.

Your chassis is not made of tofu. So no need to worry about cracking your chassis especially since you're only daily driving it around the city. Not track use.


Actually with stiffer springs, if you carry more weight (passengers) the ride is better. This happens to my VR. If alone very bumpy, but with 4 to 5 passengers the ride pretty good.....lol:rofl:
yeah, I have the same case :biggrin: but i like single driving cuz with people it's more comfortable but heavier by a lot

He drives a Perdana Evo3.....:driver:

Yup, I prefer drive alone also. Full load get comfort but drain power......lol:biggrin:
