Designed to help increase down force, especially while braking, a splitter can really help at the track.  APR and a few others make some nice splitters out of carbon fiber, which are great but are a little pricey when used at the track as these things can get banged and scratched up.  Here’s their blurb that I have quoted directly-

A Front Wind Splitter is a protruding flat surface in the front of a car that is designed to decrease front end lift and exert downforce. By creating a high pressure area on top of the wind splitter, high pressure air flow is restricted to flow underneath a car. With low pressure below the car, the effect of lift is reduced and a driver can gain from the extra traction and control.

The APR Performance Front Wind Splitter (hereinafter referred to as “Splitter”) is an aerodynamic tuning component that plays an important role in helping a vehicle achieve aerodynamic balance. Just as there are significant forces acting upon the rear-end of a rear wing-equipped vehicle, there are also significant forces acting upon the front-end of a Splitter-equipped vehicle.

EFI Logics’ master tech Jack Laverty recommended that I use Alumalite for front splitter material.  This is great stuff, stiff and light, it is generally used for big signs by advertising companies.  It is two this sheets of aluminum sandwiching a plastic honeycomb material. The sheet came 8 x 4′ and so there is enough for 2 splitters.

I traced out my front bumper and used a jig saw, which cut the material easily.  I cut holes for my tow mounts and oil filter.  It cam out pretty well though next time I might use some aluminum panels to cover some of the holes when not in use.  Also, I would extend out a few inches on the sides.  I wasn’t thinking and made it flush, thus reducing the overall benefit.

The right answer is to remove the front bumper and lay it on the cut splitter and drill holes between them both to get it aligned properly.   That worked.  I also used one of the intercooler bolts to hold the bottom in place.  You can see the holes drilled for both intercooler bolts, but one is enough.  It stiffens the whole front end when everything is mounted up.  Here are some pics.

Let me know if you want the template for the splitter or holes.
