 The
original Courage LC75 rear wing was a straight extruded section capped
with rather square endplates on either end. The vertical
extension simply helped stabilize the rear assembly attaching the
endplate to the rear legality structure. This is the very early
LC75 variant and Acura never tested the car in this configuration. |
 In early testing with the latest specification Courage LC75. |
 At
the ARX-01a's first race, Sebring 2007, the Courage wing had been
replaced
by a new 3-D profile. This wing would be used on the -01b as well. The endplates differ slightly and have
primarliy been redesigned to accomodate the modifications made to the
rear end. While the rear wing stayed in essentially the same
position, the bodywork was effectively shorted by 150 mm and the
mounting position for the endplate stabilizer strut moved forward.
|
 The
ARX-01c utilized yet another wing section, this one being identified by
the slight change in section at the outboard tips. Though also
note this is a mandatory narrow span (1600 mm) wing, these regulations were implemented starting in 2009. |
 The ARX-01c also has swan neck rear wing mounts, adopted from the ARX-02a. Also note
the solid endplate without the trailing edge notch. |
 By Petit 2007 the endplate had evolved yet again, increasing in area and now with a notch in the upper trailing edge.
|
 The
endplate area increased yet again with the introduction of the ARX-01b
in 2008. The notch carried over though appears to have increased in size. |
 The
final rear wing endplate iteration. The "pocketed" endplate
debuted at the St. Pete ALMS race in 2008 (here, Petit Le Mans
2008). |
 The
endplates attach onto a small winglet (both the large area flat
endplate and the pocketed version--both were used throughout '08,
circuit/downforce balance goals dependent). |
