You're not clear on concept here. The spoiler slows airflow over the trunk deck, and it's the surface area of the trunk deck that actually creates the downforce, not the spoiler. That's why the trucks have so much more downforce potential from a rear blade; lots more deck area.Originally posted by Dr. Isotope@May 4 2005, 09:27 PM
A 6" high, 70º spoiler on the back of a NASCAR produces 188lbs of downforce at 180mph. It's there to keep the rear end straight and kick the air around to rough the draft. At 60, 70, or 80mph, it ain't doing a damn thing. The flat trunk extension in the pic is... pretty. But don't get it as a "performance" piece. Hell, your front bumper has two gaping holes in it.
i agree, my cousin has a 99 solara with factory lip spoiler, i wish they made that for the tC, i wish i had a pic, but it basically looks like this one, but only half that size, I really like this one, but i think it is way to big.Makes the read end look like its complete instead of that short round drop off it has stock.[/b]
