Hello Insight Group. Some have asked for more details and photos, so here’s a bit about the strut tower brace. I want to give credit to my close friends / fellow EV fanatics who have contributed to the EV2 project. When it comes to anything metal, it’s my longtime EV buddy and sheet metal artisan Marko Mongillo who did a lot of the fabrication - though I’m not too shabby at it, and together it’s always a team effort.
Has there been discussion in the past on this forum, about the one under-hood part that looks more ‘shop class’ then something from Honda… I’m referring to that raw aluminum square tube 12V battery support that spans across the engine bay? It was one of the first items to be jettisoned from car, as I relocated the 12V system battery (now 13.3V lithium) to the right rear corner of the car (think Shoebox Sub zone). That bracket affair looks like it doesn’t belong in the otherwise typical Honda well done engine bay. It took me a while - actually years, to rethink removing it though, as it is a pretty stout bracket that has beefy bolts into thick aluminum structural members near each strut tower. Maybe it served a dual purpose as both a battery support ‘and’ a kind of strut tower brace? Anyone know the answer? Anyway, the last thing I wanted to do when significantly adding weight (and more power) to the chassis, was to make it less stiff.
I had co-designed and built a custom strut tower brace for White Zombie that noticeably stiffened the car. For that street legal drag car, I went with a look that matched the attitude of the car. We were in Texas at friend Mitch Medford’s ‘Bloodshed’ shop (Zombie 222 Mustang) rebuilding the Zombie after its racing misshap, when I decided to add a reinforcing brace. It was a four man creation, with Marko and I doing metal fab together, Mitch lovingly painting the brace, and Bloodshed coworker Allen patiently interpreting what I wanted as a finishing touch in the form of a CNC’d aluminum badge-trim piece:

The EV2 is an entirely different idea, in that instead of the ‘in-your-face’ brashness of White Zombie, I wanted to impart that my EV2 was something from Honda R & D, with a more factory look. The Zombie’s brace was made from steel, but the all aluminum Insight dictated that light weight aluminum would be used. Marko was totally on board with that as well. He insisted that the main transverse tube needed to have an organic shape that mirrored the car’s body - it couldn't be a straight tube! That turned out to be perfect, as a straight tube wouldn’t have cleared things if he hadn't used his English Wheel to bow the 2” square thick-walked aluminum. I designed the tower pads and the triangular firewall brace that I wanted to look like a factory stamping with a viewing port where you could see the gracefully arced orange 3 phase cables - gotta have some eye candy

Again, opposite of the Zombie’s Corvette ‘Torch Red’ paint contrasting against the white body color, the brace for my Insight needed to fit in and match the body color. I somehow achieved an auto body paint job quality lookusing a spray can of Silverstone Metallic paint

Instead of a screwed-on machined emblem as we did for the Zombie’s brace, I went with a light-changing decal - special thanks to PVS Graphics. I think it turned out well:

I used yellow zinc hardware to match the factory Honda Japanese hardware:

The EV1 motor/gear reduction unit weighs just 152 lbs. and sheds 126 lbs. off the front of the car, as the Honda engine/motor/5 speed transaxle weighs 278 lbs. The removed ☺12V lead acid battery and other removed engine bay components further reduced the weight, too… but, there’s the front battery module at ~ 275 lbs. and other EV components now.
The car feels super solid up front with structural reinforcement of the strut tower brace. In another post, if there’s interest, I could detail how the two larger battery modules serve both as cell containment and structural reinforcement.
