I believe they are known as "trunk stays" If your car didn't come with a spoiler (LS/RS) then the trunk stays aren't designed to handle spoilers. When I put an OEM spoiler on my LS, I had to switch to GS/GSR stays which were designed for spoilers. You can get stays at the dealer for about $50/side or you can buy aftermarket stays at most auto stores. Just make sure to get the ones for models that came with spoilers.
