Well, painted it black (a must) and added a support bar at each front corner of the wood,
going up to the valance. Took it out today, after also making the rear diffuser about 4 inches wider.
Car between 60 and 80 was very stable, with the nose quite planted. No jumping around or anything.
Definite improvement in that area. (The front spoiler is about a 6 inch by 55 inch piece of sheet metal attached to the lower lip
of the lower front valence. 14 gauge I think. extends 4 inches down) Cooling may have been slightly better than before too, since the splitter makes
for a larger front differentail pressure, I think. It was 90 degrees out today.
Only problem was my tires, when I turn tightly, are hitting the board that extends back to the oil pan, so gotta do
a little cutting on each side, but shouldn't be too much.
Be curious if these mods would impact 1/4 mile times much, but right now I just have my "butt dyno".
But I do feel safer at high speed now. And unless you looked kinda hard, you would probably not see these mods,
being painted kinda a satin black. You'd have to be delibertately looking under the car.
I realize the whole front spoiler and splitter are being supported by the lower front valance. And, the 2 ft by 4ft board is
supported back by the oil pan, at the sway bars. Gonna try to attach, the front area of the board, to the K member,
so at higher speed I don't end up pulling off the front lower valence.
All these mods are just what the modern cars are doing, to gain speed and gas milage, and improve handling. Except with this 40 year
old car, its whatever you can find at Home Depot or Ace Hardware.
Here's a more modern front splitter:
