Spoilers, SCCA legal Options

[Randal]

Down at AAS yesterday.

All the modified cars had huge spoilers. I thought 8" was the limit, but it looked more like a foot.

Got to figure out what is legal and get one of those puppies on 222.

Details, details....this ain't Prepared class.
From section 18.1

Rear spoilers
a. If a rear spoiler is used, it shall be mounted to the rear hatch,
deck, or trunk lid, and mount no further forward than the base
of the rear window. *The spoiler extension for the entire spoiler
is set by one measurement at the lateral midpoint of the car.
At that point, the spoiler may not extend more than 10” from
the attachment point out to the outer or free edge. This sets
the maximum height above ground at all other locations on the
spoiler. The result may be a flat topped rather than contoured
spoiler.* Alternatively, the spoiler may be mounted at the rear
of the roof, or to the rear hatch lid at or near the top of the
hatch; in such a configuration the spoiler may extend no more
than 7.5” from the original bodywork, measured as described
above. The spoiler angle of attack is free. The rear spoiler is
measured from leading, attached edge to trailing or outermost,
free edge. Its measurement is independent of its angle of attack.
b. *The spoiler may not be wider than the rear bodywork, measured
as the maximum distance between the outside edges of
the wheel well openings or fender flares at axle height.*


Read it carefully then picture in your mind that E Mod Sprite's spoiler.
The *s are mine.

7. The use of front and rear spoiler endplates is allowed. Endplate
area shall not exceed spoiler height squared. A roof spoiler up to
the maximum of 7.5” is allowed an area of up to 16 square inches
for each endplate; a trunk spoiler up to the maximum of 10” is
allowed up to 100 square inches for each endplate. Side plates
do not have to be square or rectangular; the side profile shape is
open. If end plates are to be used with the front spoiler/air dam/
splitter assembly, a maximum area of 36 square inches per end
plate is allowed.
