bro i won't sell used item to my customer
then reason you give me is the wing start shaking during 240km/h...
this reason is really unacceptable bro,
at 1st you tell me the product got problem,i did change a full new holder for you
,also directly delivery to your place on night 10pm ,am i doing a good customer service?
"normaly as every one able to see those (GT wing) already start shaking during 120km/h" i got alot of prove too
start shaking on 240km/h that is already very very good quality already,for a only RM300 product
if you want a very good M3 wing or maybe will never shake on 240km/h you able to order from original "Ac" for RM6000 Plus...im sure "Ac" also can not garrenty your M3 wing wont shake on 240km/h
im so sorry to talk all about this,but this is very comment cent.
