The build manual calls for mesh to be used for the rear hatch screen. This is the cutout located between the hatch window and the rear edge of the hatch. I have read repeated posts where people talk about heat issues related to the engine bay. One guy indicated that after 20 minutes the hatch glass was too hot to touch. Recently, I saw photo where someone had built a beautiful engine cover. My thought was how hot does that sucker get.

The louvers are shipped flat. They need to be bent and secured against the  brackets for each set of louvers. 

The mesh supplied with the kit restricts air flow too much. This is the conclusion of the builders who have gone ahead of me. This is one of the benefits of starting on chassis #402. Just like there isn't a silver bullet to provide instant horsepower, there isn't a single modification that provides the cooling and venting necessary. The solution is to attack the problem from multiple angles:

• Vent the undercarriage.
• Install the roof scoop.
• Replace mesh with louvers:
• Side vents ahead of the rear wheels
• Rear hatch
• Vent the diffuser.
• Vent the rear body
• Install a second louver below the hatch louver
• Install additional vents below the tail light assembly

Louvers are bonded and painted.

Since heat is the enemy (and this car will only be driven on bright, sun shiny days), I need to do everything possible to vent the heat from the engine bay. I purchased the rear hatch louver from Vraptor Speedworks. If you are serious about doing the job right, you will purchase Vraptor parts. I had my parts 2 days after I ordered them (Shane provides super service!)

The louver is clamped in place and the 3M 8115 is allowed to setup for 24 hours.

Most of the work is already complete. All I have to do is:

1. Paint and/or powder coat the parts.
2. Bend the louvers into place.
3. Attach and bond the brackets.
4. Bond to the hatch.

Finished install.
