They designed that splitter for last year's SEMA show, sorry it has been over a month.
I think you can trace out the outline and they will make one for you. Feel free to come to any of our races and trace it out (www.USTCC.com
You might want to come to the Sonoma race when the WTCC come out to join us as well (http://www.fiawtcc.com/
), I can probably even comp you a couple of tickets.
