front spiltter?

OK guys to give you some info. I am highly competitive. The places i run the track at, we don't have classes. I am doing my best to out run my buddy on the course. He has is coming back from Iraq in a few months and i already have seen the kinda money(money that i don't have to spend to keep up with him) he is sinking into his tc. Plus to back it up he is not a bad driver. I am looking for a few things to do and to give me a new project. Who all has a splitter on there car and how do you like it? pics if you have them.



P.s. I am gonna make my own splitter( design it and build it).

thanks for the links but i am going to build mine. I have been crunching numbers and going over the best design for the car to do a complete under body. I honestly need to find cheap way to measure pressure a different points around the car so i can get more data and also to make sure when i do build this thing that it doesn't mess with the flow to the radiator.
