    Here are a couple of pics of the splitter for my race car. The bumper cover is from Moseley Motorsports and the splitter is made of alumacore. There is a 1.5" spacer between the alumacore and the bumper cover. It mounts in the front in the normal bumper attachment position and then has four 1/4 turn Dzus fasteners; two on the sides and two to brackets on the front subframe. It will be painted to match the car.

        Nice Damon,
        If you dont mind me asking, what did you use for a spacer?

        I have a spare bumper that I am doing a splitter for and needed to space it downwards a bit, I was having a hell of a time finding something that would be structural enough to take the load, conform to the both shapes and not weigh more than the bumper cover and splitter together.

        In the end my solution was stand offs made from rubber (almost like small hockey pucks) to take the load, and then filling between bumper bottom and splitter with closed cell polyurethane foam,,, but I'm still not crazy about it.

        Looks great.

        Cheers

          I bought all my fiberglass parts (not counting doors) from Moseley Motorsports in the UK.

          Hi Jimmy,

          I used solid foam insulation cut to match the shape of the bumper cover and a number of bolts washers and nuts spaced approximately every 12"s or so to tie it all together. On the front and rear of the insulation is racer's tape.

          Once I settle on the overall ground clearance I can live with, I may fabricate an aluminum cover for the front of the insulation. The nice thing about using the hard foam insulation is that you can add thickness by gluing pieces together and it is easy to cut.

          Because of the shape and the number of bolts I am using, it is structurally sound and light weight.

              Are these wider than stock fenders?

                How much ground clearance are folks going for with the splitters?

                Any potential cooling issues when the splitter is extended past the oil pan?

                  Hi lee, yes these are quite a bit wider, they are the competition concepts fenders.

                    Nice. Looks a bit like my bumper. What are the brake calipers?

                      They are the wilwood sl6 calipers from massive brakes rally kit. I love these things.

                        Nice dive planes!

                        Are you using the E3 bumper seal? I see something there.

                            Are you talking about on the top of the bumper? There are some seals that have been there ever since I bought the car, I kind of always assumed those were stock?

                              Yeah I hope to see you as well, have you been running lately? I'm going to attempt to start racing with NASA GTS this coming year.

                                Ed, they look like the stock multi-piece US bumper seals.
