    Default Homemade race car innovations

    Whenever I walk around a paddock, I'm always intrigued by the handmade, home-built stuff people come up with. Or even stuff that pro fabricators come up with. Let's start a thread with some of the things you've seen or done. I'll start.

    I just finished this. It's a remote release for the trunk. When we did the WERC enduro last month, I discovered I couldn't reach the fuel door or trunk release inside my Miata. I'll pull the fuel door for the next enduro, but I devised this so the fire extinguisher man can see when fuel back up the clear fuel-fill vent hose.

    The handle was $30 from O'Reilly auto parts and it took me about an hour.

    Well, I just finished something that isn't half as clever -- but it's light. The stock rear tail light buckets on a 911 weigh just over 4 pounds each, and that weight is all the way back in the chassis, where it's only making a bad situation worse. There are some aftermarket fiberglass replacements, but they cost an arm and a leg. I hit on the idea of using LED assemblies from a submersible boat trailer setup. That freed me from having to make a box that was weather-tight (like all the rest). So mine is made out of aluminum sheet and the array of 20 LED bulbs gives better, more-disperse light than simply replacing bulbs with their LED equivalents.

    Heavy (64 oz):



    The lights I found weigh less than 4 oz:



    The box doesn't weigh much at all. It's the plastic lens that's the killer:



    But the finished priduct is a svelte 13.8 oz:



    With and without the turn signal flashing:



    The 'factory' lightweight solution looked worse and weighed more.

    Removing six pounds of taillamp housing. That is clever. I like how you swiss-cheezed the sheet metal.

    Here's another one I did, and I know it's clever because it wasn't my idea. I picked this up from a racing motorcycle at what was then Moroso Motorsports Park in Florida.

    The rider blanked out his tach with electrical tape below where the power band came on. If I can see the needle, great. If not, I was too slow or in the wrong gear. Or both.

    oh geeze, where to start.

    Don't have anywhere for a magnetic drain plug? Just stick a magnet to the outside of an aluminum part:



    Everyone laughs at my droop travel limiters, but they work great!



    No dearie, you don't need to run your wing supports to the car frame:



    Got aero understeer? Not when there's Home Depot!



    Rear-facing camera sound like too much hassle? Think different.



    OBDI crankcase vent filling your engine with oil? Grab a catch can, stuff it full of gutter leaf guard foam and turn it into an oil separator:

    Poor man's radiator ducting.

    Alumalite for the rear and sides. Aluminum for the bottom.

    Add a plate to create low pressure, assisting with the egress of radiator exhaust.

    Then it goes right into the cabin, via the center vent. Need to do something about that.
