I really like the GTO spoiler, It was a GMPP, It is functional, So its kinda like a RPO (well almost), GM doesnt still carry it but Corvett Central lists it for 379$, It would be way slick to section and mold it into a glass rear bumper... have I made enough excusses to get one yet?
LOL... Pink yet... Can I Rattle can it black?? and does it adjust ? I want to "Maximize my downforce"
i dont know what your talking about with downing the force, but i put on a big carbon fibre spoiler and my 0-60 dropped like 2 seconds. i predict my cars just about as fast as one of the new ferraris
I have a 1993 Coupe. I found a used spoiler and bought it (for $80) after examining it for flaws in the gelcoat. Turns out it makes no difference since gelcoat repairs don't work as well as judicious application of sandpaper and glass impregnated body filler.
It was an old IMSA spoiler and determining where to make the holes in the rear bumper (and screwing up the nerve to make the holes) to match the four vertically oriented studs in the horizontal part of the spoiler (that wouldn't remove) I made the holes. Knowing that the holes had a slim chance of being in the right place I drilled, with a step drill, to the approximate diameter of the studs. I put some chalk on the studs to make a mark.
Ha! Oddly enough it didn't fit where I wanted from a front to rear orientation perspective. Kept increasing hole diameter till I figured out that it STILL wasn't where I wanted it. Used a round file to move the holes forward till it seemed to be where I wanted it. Then I found the side surfaces wouldn't fit anywhere near tight enough to the body.
I cut the top off a pair of 1/4-20 bolts and ground a point on each. I then glassed a nut into the lowermost part of the side surface. I screwed in the pointed studs (with points out)and lowered the spoiler onto the car, with the wife's wondering help, and oriented it where I wanted it and released the sides. I then hit the sides with the flat of my hand to let the points make a mark in sides (left and right) of the vertical sides of the bumper cover. Drilled the cover on both sides. Removed the studs and started the replacement capscrews from the inside. Then I put the nuts on the studs in the horizontal part and pulled them down where it fit nicely. Then I tightened the side bolts and it fit well. All of this is done through he license plate hole after I removed it (and the backup lights).
I then did the remaining body work on the car, prepped the original green paint for paint and now you see the rest of the story. I am happy and am relatively unconcerned with what others think. I like it.
When, and if, I get to 150MPH I know it will make a difference in handling. It does seem to make the car stick better at 80 MPH when passing large trucks and in strong cross winds. It makes logical sense that you would sacrifice some fuel economy with the added drag but at this point I don't care. It gets much better gas mileage that my wife's 2008 Toyota Highlander and accelerated, sounds and handles much better.
Your thoughts?
BTW I tried to post several photos for your review but the system objected strongly so maybe I get the Administrator to turn on my attachment rights.
