mana ada le.. airport lo..

me lo. but mine 19mm.. 

finally ventures into bawah pokok service.

Stiffness calculation for the spring rate of solid anti roll bar as below:

                            Pi x G x D^4
                            --------------
                              16 x B^2 X L

where G= the modulus of elasticity
D= diameter
B= length of lever arm
L= length of bar

So, 19mm solid bar is around 2x of strength compare to 16mm.

Below are the list of stock vehicle I've put my hands on:
Hongda Civig FD - 12mm
Hongda Civig FB - 12mm
Hongda Agord - 12mm
Fork Lynx (2001) - 12mm
BoBo 244GLi(1988) - 12mm
Toyol Altis - NIL
Dugong - NIL
P42 - NIL
Wigra - NIL
Shawie - NIL
GaGa - NIL

Now, your car doesn't have an ARB in stock form. Whatever 16mm added to it, it's extra to your car, usually ARB are NOT supposed to exceed 10% of total spring rate(which after added it will be far beyond the limit). I can't brain what 19mm would do to stock springs. From what I can tell in my previous experience

1) too stiff spring that causes too much of bounce(air time, tayar tarak sentuh lantai mau macamana grip?) as a result lose control at corner.
2) Over stiffen ARB, resulting in inflexibility for both rear wheels. As a result vehicle will behave cigaoxin. Sometimes grip, when grip finish the car just spin out without warning.

So, no say good or no good geh. Sometimes I understand the being Asian mentality - bigger the better, including their d*** also wanna compare whose is bigger. For me, I did my own home work with UNKNOWN FLX rear spring rate, knowing the definite of exceed limit. I know I will not be able to break the ARB regardless how crazy I whack the car, probably break the torsion beam 1st if I were to. I don't know how about 19mm cause I didn't try. So yea, please go ahead if you think it's good. In the end no 1 else came up with the comparison of spring rate whether they're suffice/over limit.

haha u didnt c mine.. ken lew mangamuk... so many white smoke...
