Your local Toyota dealer. Expect to pay through the nose, because they aren't cheap. Like, to the tune of 3 or 4 hundred bucks for each piece, so, that times 4. Only alternative is the Thai Hybrid Camry ones which a few here have, which are genuine Toyota, and can be had for around $350 plus shipping. These ones are slightly different to our facelift Sportivo ones in that the have a slight blue tinge and a small red section, as opposed to the Aus ones which are all clear. You have to order from RStyleRacing (or you may find some elsewhere online, but still unlikely to be from Aus) unless somebody here wants to part with their set. thanks :)
