  • Home Made GIANT Front Splitter

    I built this splitter to maximum specs for Street Modified. The splitter extends 6" forward of a vertical line down from the front bumper. I installed to studs on the bottom side of the from frame rails to make the splitter able to slip on easy. Underneath on the crossmember are two more attachment points that pins go through to hold the back up. There are 5 heim jointed front support bars to aid in support.
    The first version was made from cheap 3ply plywood as seen in the photos. The second version was made from 9ply 1/2" birch which is 100% more rigid. Also my second version has brake ducts in the front. The only pictures of it I have up right know are all of the GotBlueMilk photos at Laguna Seca.
    Hopefully I can get some more photos up when I was making it and the attachment points.

    If anyone has any questions on how to build or is local in California I might build another one so let me know if you are interested.

          I'd love to see the attachment points under the car. That's the part I just can't get my head around. I guess I need to actually grab one of my NASCAR splitters and put it under the car and see where it sits, then find some structure to attach from there. I'll never get it done if I don't ever get under the car.

              Mine is similar to 240SX_Racer's. It is bolted to the tension rod brackets underneath. There are two threaded holes on the tension rod brackets that are there for the stock plastic undertray. I also have a rearward facing heim joint on either side, which is bolted to the end of the stock bumper support. In the photo you can see the bracket at the back edge. Also there are four heim joints in the front. 6 total heim joints and the 2 bolts in the tension rod bracket. I'm in the process of added two more heim joints on the corners.

                  Awesome! My hat goes off to you sir (and you as well 240sxTTC). I would love to see the attachments underneath the car as mentioned before, would be highly appreciated.

                  Concerning the flex, wouldn't mounting a metal rail diagonally across (on top, out of the wind) aid in allot of strenght, thus reducing if not eliminating flex alltogether?

                      where did you find/buy the lower 'bracktes' for your splitter? I think you mentioned McMaster but I simply couldn't find them. (and if yo uhave all of the parts, I'd like to verify that I saved the right ones)

                      Thanks!

                        At first I was going to say nice fab work on the front lip...

                        Now I am going to say, YOU GOT TO RACE ON A TRACK WITH AN F40?!?! I hate you.

                          Very cool stuff. I'm highly interested in this for my car. Not quite there yet, need a month. But I would really like to see more pics.

                            Old thread revival.

                            But...... how much do these completed ply splitters tend to weigh? I've been thinking about constructing my own but can't decide on the proper thickness to start with.

                              My splitter is 1/2" birch and weighs 15lbs with hardware. 1/2" is overkill IMO. I can stand on the front of it no problem. I think 1/4" birch with struts near the leading edge should be strong enough, and definately lighter.
