I thought I would share my experience installing a rear deck spoiler. Here's the parts you need. I got mine from Sewell's Lexus with the Club Lexus discount.
Here's what you get:
You get the spoiler, drill template, replacement springs, nuts, bolts, spacers.
Remove clips from top side of trunk so it can flex. You aren't removing this piece.
Remove clips from side trim panels so you can pull it out to access springs.
Prop up the trunk lip before removing the spring. Remove the old spring and discard. The new springs are shorter to offset the weight of the spoiler.
Install new springs and replace trim panels and clips.
Remove 14 clips holding the trim on the underside of the trunk. Remove trim.
Place tape on rear deck where the spoiler will be installed.
Install template by placing tape in the designated order of the template, smoothing the template as you go along.
When the left and right templates overlap in the middle, the alignment marks should be centered.
Using a center punch, tap the deck lid in the four locations so the drill has a starting point.
Remove the tape and de-burr the holes.
I painted the raw metal edges to assure the edges don't rust.
Vacuum the metal burrs before opening the deck lid. Also, open the deck lid and use a flexible magnet to clean the burrs from the inside of the deck lid.
Place 3M Ultra-Pro Body Sealant around the four holes just before installing the spoiler.
Install the spoiler and tape it to the deck lid. Once done, open the trunk.
Install the supplied spacer and bolt/nut to the left and right side. Do not tighten so the double-back tape tabs can be pulled out in a later step.
Once the bolts and nuts are installed, close the trunk, center the spoiler from the edges and pull the double-back tape tabs from the rear side first. Push from the rear and set the tape. Now pull the front tabs off and push down. Open trunk and tighten bolts/nuts to 23 inch pounds. Re-install trunk trim.. You're done.
When I bought my car, I did not even know a spoiler was an option, and it was not on the spec sheet when I bought it. But it was at an out of town dealer who had a buyer for the RC that my salesman had, so they agreed to swap. At that point someone said the red car was down in the shop getting a spoiler put on it. I found a photo of one in the options booklet, and it looked like the ones I had on my SC400 and SC430, so I said fine, and I'm glad I did, as it's a really nice look.
Pogman. Thanks for the write up. I used it as a guided and got mine installed yesterday. I struggled a little bit with putting on the new speio but the rest of the installation went well. Thanks again.
Glad it went well. I always thought it added a nice look to the rear. I've sold my RC and entered the vintage car phase of my life replacing the RC with a 1966 Mustang 2+2 candy apple red fastback. Talk about a change in ride and quiet!
