just about ANY wing/spoiler that says its for the CELICA 2000-up, will fit without drilling.
when I say fit, i mean it will fit your stock spoiler holes - replace your stock spoiler... but obviously, if you dont have a spoiler to begin with, you WILL need to drill
The spoiler that you see people having to drill for are those spoilers called "universal"... yeah, universal if you have a HONDA
Some celica spoilers right off the top of my head:
Kaminari Wing / Race WingTRD
Adjustable with 3rd Breaklight
Rod Millen Carbon Fiber
C-One / Tie-Fighter Style
Veilside *hard to find & expensive!
Molly Spoiler *discontinued
Carcept *import from UK
