That explains why I hear some people reduce their tyre pressure when they plan to go out for touge drive. Want to follow race setup. :biggrin:
Cannot simply lower one. Even for track days, they measure the air pressure after warm up lap, then adjust according before race. Even low got it's limit......:biggrin:

Din't know that tyre pressure is taken into account that seriously on track days.

Not so sure sound proofing can still enhance anything much because the car is a F30 320i. Engine is quiet even when nearing redline at 6000rpm. That is why on normal cruising, the tyre noise can be heard clearly.
Try to add few layer of spray on type of bitumen/sound insulation solution inside all the fender. It might help.

Different type of road surface will still give you some noise no matter what tyre u use...

Need to find shop to do it or can be easily done DIY? I already told my friend about the noise probably comes from his run-flat tyres. So, just wait until he changes his tyres first and see what he says. If he still complains about road noise, then I will suggest this method.

Not a good idea for my friend I think. Removing the wheels is troublesome for him as he asked me before on where to do plastidip for his wheels. I told him he can DIY but he said he can't remove the wheels by himself.

Sure is loaded. Since you know my age and my friend is also in the same age with me but driving F30 320i already. To be honest, despite always visiting zth myself, I have not even tried any major DIY myself yet. Inexperienced, lack of mechanical tool skills and don't have anyone pro enough to refer to nearby.

Starting out is always difficult. You need to know someone who already doing DIY to learn from him. For me, I learn mostly from my mechanic. I stay whole day long watching them when servicing or repairing my cars, then ask question if don't know or not sure. Then start buying tools that are needed bit by bit. Now of course we have group up and have sifu Izso, when we do our DIT....:driver:

True. Sometimes it is not that easy to do DIY despite reading about it on the internet even with pictures. Definitely helps a lot to have someone who are good at it beside you.

I tend to stay and watch my mechanic too when he was repairing my car. Since he knows that I am interested in cars, he will also tell me about what part is this and that. He will also explain to me about why and what is the reason behind the parts that are broken.

Well, if your mechanic willing to part some mechanical knowledge to you is good, that is a good start at least you know what wrong or what fails in future, like the battery light came on, you thought it was battery, now you know can be other things like alternator.....:driver:

Hahaha, that is true. He usually will point out the symptoms of faulty parts to me like some noise that broken parts will produce, hardened and cracked rubber in mounting and also hardened oil seals which he will always tell me "See, hard like steel". :rofl:

Also, he will occasionally tell me that I am a newbie because there is so many things that I don't know. Well, he is right because compared to him, I am like so far behind. :biggrin:

Mechanic is my grandfather's friend. My grandfather knows him for many years already while I just got to know him in recent years. Is just a small workshop under some large trees with him alone working over there.

That day while I was there to replace my alternator, I asked him for confirmation about the rough price for a replacement unit alternator. He laughed and told another uncle which is also there to repair his car that if he want to con me, sure get caught already because I already checked the price of parts before coming. :biggrin:

But sometimes cannot be helped if you are not getting the parts yourself. My mechanic i have known for many many years already and his family and my family are now family friends too. Sometimes prices higher could be due to his spare part shop supplying him the parts. If I can get cheaper he will ask him to buy and bring, but usually for my car I leave it because if buy wrong parts I cannot return. For him he can or sometimes he need to remove and use as sample. Probably for your wira is common, not for my VR......lol

I just asked him about the rough market price, not I buy it myself. What he is trying to say is, can't really con me since I already checked the market price.

When it comes to buying parts, I leave it to him too because he will call for a few spareparts shop to check which one is cheaper. Normally before buying, he will ask me which one I want. Usually it is either original, 3rd party (good quality) or 3rd party (cheap and lower quality).

Same for my mechanic, he bought wrong parts he can return it. Once he bought the wrong radiator hose for my car. He took the one for VDO instead of MMC. So he went back to return it.
