actually half inch difference, stock size is 23.3" and 15.5"

sorry, actually not 23.3" but 23.5"

23" should be okay i think if you want to replace

i bought 24" and it hit the a pillar when you set the wiper at full speed

last time i using 24" hit the pillar... and hard to find 23" so change 22".. however now passenger side plak hit the pillar.. 16"... original use 15.5". i think i want to ask the sc to adjust the wiper..coz last time passenger side no problem using 16"

FC Update:
23 km home to office, 8.2 L/100km. Hmm that's surprisingly good.

Observations:
Too much turbo blow off sound. Even below 2000RPM, such as 60 - 70 kph. Every time the car infront slow and accelerate a bit, you have to release and press the accelerator quite often. Every time you release the accelerator you hear the blow off sound. That means there was boost, even at slow speeds.

Regarding wiper blades, should we measure and make sure it wipe over the rain sensor?
If too short and it can't reach (wipe) the sensor, then the sensor keep reporting heavy rain... 

Yess. after first time pump at petronas, driving through bangsar at 10am traffic, i see the FC go to 22l/100km. 
Hahah. maybe more difference for the Turbo users if they test ron97. im curious also what's the difference. anyone here willing to spare rm20 petrol to test on their car and review?

Anyone replaced their noisy front seats recently?
Thanks again.

Seriously, if I do see a Preve go kepish kepish pass me on the road, I can only shake my head
