it was me.. well.. i bought the full set, Big-D, Small-D and P-Shaped..
from what i see, its totally useless for a new car, in fact, it worsen the noise..
the original rubber at our door is actually doing good its job good enough.. i thought, after install that additional rubber, can eliminates the sound like 100% one.. but its actually not that what ive expected it to be.. the rubber was actually making the door harder to be closed.. have to bang hard.. and when it closed, now the gap is larger compared with before installation.. well i guess, for vehicles which is more than 2 years and frequently park under hot sun may benefit from the extra rubber.. but definitely not a new car.. in the end, i just use the P-shaped wan to install at the bottom side of the door so that excess water wont come in.. what a waste of money..
p/s : oh yeah, if anyone wanna ask, the answer is "no, i didn't install it wrongly.. its the seller who installed it for me himself, exactly like he installed it at his car.." btw his car is persona-se.. but hey, if anyone wanna try to install, by all means, carry on, maybe the result is different.. as for me, ive already take out the rubber and being happy with the oem rubber..
did you let the rubber for 1 week? Even after 1 week also hard to close? I think install the sponge rather than rubber.
