oh wow..i saw the rear lip, and it is off.
yeah...you might be able to get away with the blitz/buddy club..they are not much off, but the buddy club is a little bit lower.
other than that...
rmm/kaminari/ww go well together. you shouldnt have a problem interchanging themTRD
is pretty much stand alone. its the highest out of all the body kits for the celica (and it should be--its a factory option).
blitz and buddy club go best just by themselves, but i've seen a couple of mix & match cars with these parts and if you look close you can see that they are off..but its not THAT noticeable.
veilside i'm not sure of. i've seen a blitz celica with a veilside rear..but it was kinda hard to tell what was up because the veilside rear angles upwards so quickly. it was off, just not as noticeable because of the angle.
