Lexus IS200 chassis

Hi to all Gurus here,

I have a problem with my car. Everytime i drive the car, i will hear small 'click click' sound at the rear part of my roof. Then when i drive my car on roads where the degree is different for eg; climbing up multi-storey carpark or so, i will hear some 'kluk klak' sound coming from my roof..Does anyone ever experienced this problem before?..i think my chassis need to be strengthen or anything.. Please advise..tq in advance.

yes i have this problem before, it only happens sometime and not always to a certain degree, it is due to the car chassis twist n flex, however i got mine done up with "autofoam", and there is no more sound coming from the chassis / roof. Autofoam, it's a foam pump in to ur car's chassis to fill up the hollow frames, pillars & sills. There is a couple of package available based on your budget, but my recommendation is to get the ultimate package which cost me around 2k+...last year. I get mine done at klauto...please see the link below for location and details on autofoam...

TQ cash1212 for the reply..I've heard bout this product too..Even, i asked for quotation for my car anf they quoted at rm2480 for the ultimate package..So, by doing this, my clunking sound from the roof/chassis will dissappear?...hmmm..think i need to put up this item to my to-do list..now i got bushings and shocks to be replaced, plus the autofoam..sigh :( .... but, if this product can make all my headache go away, then i'll go for it i guess...

Another thing, what about UltraRacing bars?...do they help to demolish the chassis flex n twist too?..

welcome. I did mine for 2.1k actually after bargain la...wa u have quite a lot on ur to do list as well huh...slowly la bro..1 thing at a time...if not can die...i just change my coilovers and bushings as well. I change both front and rear about 2 months back...feels like new car after change...:)

When you say ultraracing bars do you mean Anti roll bars?? my guess is ARB's that ur talking about, i would not say that it totally eliminates or demolish the chassis flex n twist, after installing mine, i only notice that it increases the suspension's roll stiffness, its resistance to roll in turns...feels a lot stiffer...when i go over a bump too..

hahaha...i envy u..u got AutoFoam, n some more new bushings n coilovers..Your car will definitely feel like new..

What i meant by UltraRacing bars was the front strut bar, rear strut bar n several more bars designed by UltraRacing to improve our car handling n response. see here --> http://www.ultraracing.com.my/

These are most likely similar to other 'chassis tuning' bars sold by other manufacturers i guess. But, just wondering which one is better, or applying both the AutoFoam n UltraRacing bars is better..hahaha..i sound like a very 'tamak' person..

Anyway bro, how much do you spent on your new coilovers n bushings?..n what are those?...do u mind sharing as i want to replace them too...tq

 

[cash1212]

no need to envy me la bro...i also slowly slowly done up 1 by 1...by the way i am only using very humble tein superstreet coilovers and TRD & PRO RS bushings for the front and full TRD bushings for the rear...for the coilovers and bushings, i spent a total of 6.8k all together...but worth every penny....

i have no idea on ultraracing as i have not used them before so can't comment much...sorry...

 

[shauqi_wax123]

Tq so much for the infos...If u dont mind, how much u spent for the bushings and where did u changed n purchased them?..
As for the Tein SS, i dont think my pocket is ready for that just yet..might just purchase an OEM ones only for the time being..hehehe..

 

[cash1212]

TRD bushings i get it from Wing Hin and Pro RS bushings i get it from Hokomoto racing....for the full set TRD rear bushings i paid 2.4k and for the front TRD bushings slightly lower a bit + Pro RS bushings, just for 1 part lower arm bush i paid RM 600.

TQ so much for the info..really appreciate it...now i know how to do the budget for the bushings..
