    This is getting exciting. Printed out a prototype in plastic to check basic geometry and clearances.

    I gotta say, even this early prototype is looking amazing. Clearances still as tight as before, but everything fits just fine.

    Eagle eyed viewers might notice that this is actually a right side bracket (with the clearance for the positive terminal) that's been mirrored over to look like a left side bracket. Wanted to get a feeling for the thickness of the bracket in the area around the positive terminal and at the same time wanted to check clearances against the engine wiring harness box. Doing it this way meant I only had to print out one prototype.

    Worth throwing a pic of the other side up for comparison, soo much worse:

    Here's some pics of the mostly-final CAD. Biggest difference is that the holes for the top hat studs are now slotted so that the top hat can move around for camber adjustments and the strut tower brackets can stay in place:

    Same pics, but this time with the stock part (purple) overlayed for comparison. Gives a good sense of where I added material to take the extra loads:

    Eagler eyed viewers might notice that this version does not have the "ridges" around the rearmost stud holes for the nuts to sit in. I tried including them for max stock-ness, but the slotted geometry means they interfere with the center "///M" trim piece, so will have to go without them

    Next up is printing another prototype to test the slots and running a bit of FEA as a sanity check.

    I also want to try extruding the bottom surface down to get rid of the bosses and make the part totally flat underneath. Not sure how well this will work with the existing geometry, but we'll see.
