yoko a.drive r1 is fine.  hankook v12 is another alternative tyre with good performance for it's price.
bear in mind, any directional tread tyre are noisy by nature. even more for performance tyre and as the tread wear out.
avoid my-01. lousy grip ( that's why i am using 'em to learn drift ).
falken 912 is fine for it's price but tread wear out faster.
i am currently into ps3 on my main ride which is of asymmetric tread. slightly softer sidewall but it was equally good in wet and dry!
not to mentioned being quieter.
pu steering bush cost 80 bucks with installation. z racing somewhere in the mines(balakong) near shell area. you can watch 'em complete the job.
steering feels tighter and more responsive after changed to pu. excessive vibration sometimes could be caused by uneven / excessive tyre's tread wear.

not so sure about 16". should be around 440 bucks each.
am on 15" and 17". 195/55/r15 cost around 240 bucks each while 225/45/r17 almost 600 bucks each.

but this afternoon, drive my car out and there is a soft rattling sound from the rear passenger (left side) on the car.
already checked the rear seat zip, boot area and even the door. sound still there. very annoying.
any idea?

it is not difficult to remove and after reinstall it wont create noise except you didnt screw well! it is a small light bulb behind the meter where you remove it using a long nose or using hex 6mm. You may get the bulb from any sparepart shop.

There is no brighter bulb but you always can replace to EL lights hehehe
