Well bro, i personally think the undercarriage need soundproofing, since the road noise is there still.
It's not that bad, but I think it would be better if the road noise can be reduced even further, simply because we don't need them at all.
The engine bay soundproofing is superb; there are still people didn't realise my M3 approaching them from behind

I done some research on sound proofing.. and I just back to my hometown.. looking for some car accessory here too

Hope they sell the LED light here cheaper. Well the main part we need to install the sound proof pad is..
1. The roof (if possible, scare void the warranty

)
2. The behind boot, this one easy but you need a good hand to stick the soundproof material around.. (I think this need the most)
3. Front Wheel (The are around the wheel, I don't know what that call), because i can feel some minor vibration inside the car where the Air Bag area.
Thing to find in my hometown.
1. LED Light for my car boot not the front

2. Audio Player? ( see any cheaper than KL or not )
3. some car accessory if possible.
