After doing some intensive research into functional hood vents that maximize heat extraction while also generating useable downforce for my SHO, I found a company called Race Louvers. This company has done extensive designing and testing with CAD software and wind tunnel test data to bring true, functional louvers/vents to market. Upon looking at their site I wasn’t surprised to see there was nothing listed for the SHO...big surprise but also not a big surprise due to how small our community is. After measuring my car and sizing what I believed to be the optimal sizes for louvers/vents on the SHO hood, I called them and took the time to get a professional opinion on the shape of the SHO hood and what would work best for our platform, given the current vent/louver offerings at Race Louvers. Then, working closely with Race Louvers, we determined which of their purpose built/functional louvers/vents would give our platform the best heat extraction and downforce. Unlike Track Spec, hot rod stamped louvers, HVAC vents, and open hole/mesh configurations, Race Louvers has engineered their louvers/vents with optimal front wicker sizes and optimal louver/vent blade angle of attack to maximize high pressure air extraction which increases downforce, and maximize heat extraction which improves radiator and intercooler efficiency. According to the aerodynamic test engineers and experts at Race Louvers, this is the most optimal placement and optimal configuration of the louvers/vents. This configuration and location is critical for performance and not just placed accordingly to look cool.

I was able to help Race Louvers combine a set of hood louvers/vents ideal for our platform and now there is a complete kit available. I am now a Race Louvers authorized dealer and can offer this kit to you guys at a slightly better rate. Win for Race Louvers and Win for us. Check them out.
Kit is available in two different levels of performance: RS for street and RT for track w/ pricing for each trim level the same. Please see link below for differences in trim levels:
