    Finally got to see this in action a few times. Here are my quick thoughts.

    1) Does it work? Yes
    2) Are there problems ? Yes
    2a) Front angle - to compensate for the bending, you have to increase resting angle. Can't use angle plate so I used a screw with spacers to set the angle.
    2b)Lot of moving parts - There is a lot that could go wrong so it's not something I would recommend for newbies on race day.
    3) Yes, I'm using the rear MS piece in the front for the extra clearance.

    There are a few versions of this already, and someone out there on instagram beat me to a better a design where each side is independant. Which is where I'm headed next.

    So we finally get to see this front bumper, I like it....I made almost the same thing but following the principle of the FL system. It worked pretty much the same but just looked a lot nastier than this. After seeing this, I might try it again.

    Just one question, wouldn't the rubber ring in the middle that pulls it back down work better if it's run under and around the back rather than down the front?

    Ha, I just remembered this reminded me of something I was trying to do, although at the time it turned into the frankenhorror front FL system. The highly flexible AT sliding damper, you could also attach it to a frontal flip to give it a little more freedom of movement.

    I eventually found an image of someone that had made it but can't find it again. This is just my attempt at working out the system, if I do go ahead with doing it, I would make the popsicle longer and use the two holes closer to the middle of the frp.

    Here's it working, although it was pretty rough because I didn't take time to clean it up as I was just using some crappy imitation frp.



    Think this might be worth building chris?


    Also, when I look at yours, I'm wondering, in it's natural resting position, can the pivots actually work or does it sit rigid until landing on a wall and collapsing?

    Although this is the frankenhorror, I was having issues with it, I wanted it to pivot for corner dampening, not just landing on walls, this is how I solved the issue, messy, but it worked, the pivots could sweep back and rise when dampening as well as collapse when landing on a wall.

    Just saw this, looks really interesting and easy to make for both front and rear I think.



    Edit:

    I tried making my own, it's actually quite easy.

    Edit 2:

    Just finished making front and rear, might need to rebuild it depending on how I use them, car would be far too long. Anyway, here's a look at the finished stays.
