Alwaz welcomed, Bro!!
Glad 2b of help...with my very limited knowledge...

Re brake pads, mayb due2 bedding in or material used ie semi-metallic.
Hv nvr used others except OEMs...also in ole rides. Me slow slow driver lo.
However dun think need 2bleed brake sys. Only bleed when spongy pedal feel ie air in fluid.

Hope other Bros can help re sound...?

Me put front strut bar only.

Most support not need rear ARB cos got torsion bar suspension.

Am wondering, does strut bar reduce lateral movement (as in left and right swaying, not bodyroll) when going straight on uneven roads, like our beloved PLUS highway.

Change to BLM standard spring, you wouldn't have that anymore

no way to fix la bro, or may be there is I didn't know. According to my understanding on the car's foot work, either hard or soft. Install strut bar will NOT solve your swaying problem. Strut bar is there to avoid your chassis being compress during high speed cornering. From my experience, lowering the car with progressive spring + terbalik absorber(sucking type instead of pushing type), that will really glue your ride on the ground I was using this type of absorber on my KE20. There is very little chance the car will get flicking out of the line on uneven road. HOWEVER, you'll suffer insane gravity pull/rejection from your car. You'll feel every uneven terrain as a BOUNCE instead. I still remember there was once I brought along 2 of my mates to Penang to visit chick there, after JURU toll there's a stretch of uneven road, when reaching the Penang bridge toll, we had to stop cause my mate at the back start vomiting. As I stopped the car, the passenger also start vomiting. In the end, I smell those crap I also beh tahan roll down the window start vomiting. UEEkkk.... Please consider GAGA is very "tall", provided FLX SE came with 15" wheels, added to the height, the car sway abit is fairly normal la

Aiya, I know it's normal la. Question is how to reduce it.

Guess lowering my ride is the only option, which is not an option for me at all. Summore thinking changing to 55 profile tires summore, getting taller and taller
