visited joi seng once. Nothing really to complain except camber nut need to change. same like majority of "confirm camber nut need to change" tyre shop out there. Wherever you send your car, be aware of what's going on. Some have respect for your car. These shop I gave respect back. If they say the camber nut needed to change because it really needed to be change. Not because just wanna suck your money dry when they can do the camber just alright without changing it.
