glanza sideskirt, glanza rear bumper, glanza bootlid and spoiler, glanza front bumper, glanza bonnet and glanza headlights. if you want to go the full hog you can also get the glanza mirrors and interior
For the rear bumper the spray flaps/liners are different seen as the bumper is deeper I know as I got mine from Toyota new. And I am pretty sure the front is the same but I have not fitted the front bumper yet.
There what give the corners of the bumper there stength and stop them flapping. All so they stop the stones and grit hammering your body work so I would say there needed! But I aint one for penny pinching or corner cutting but that's just me!
