Now for something really cool. Finally, a detachable racing wheel! This took quite a bit of work. The Model 3 is different because its steering wheel buttons are critical to operating the car. Computer reset, mirror angles, & steering wheel placement all happen through there. And from what I...

Custom - these guys only do it for professional racing teams; I just happened to know some people. But I'm actually doing some revisions. The first were good, but not yet perfect. If there's enough interest I could look into setting up a group buy. Maybe send a DM so I know it's worth taking...

191 lbs. Probably over 200 with baseplates. Could have saved a chunk of weight, maybe 30-40 lbs, by just building to min requirements (e.g. one diagonal, no rear cross bracing, no gussets). But after racing long enough, you see enough wrecks and you know enough people that get hurt, and it's...

Finished product. Clean. Passes tech for SCCA, NASA, and a number of other sanctioning bodies.

Harness bar in, going to paint-

Cleaning off sound deadening from floor- Welding- Cage and rough-fit seat before adding harness bar- Test fitting seat- Custom seat mount & harness hardpoints-

Floor is extremely thin. Added extra reinforcement to the baseplate to spread the load in case of a rollover event, so the tube is less likely to puncture into the battery-

Lots to share since my last update. Trying to decide if it'd be better to just do a full build thread or not. But for now I'll just share some highlights: Dropped battery and removed glass in prep for cage welding-

Totally stock? 12v battery is probably your best bet. @MountainPass makes a kit that shaves 20+ pounds and you'll never see it under the front trunk. For 0-60 performance like in this thread I'd say aftermarket wheels, rotors, and tires. You can shave a fair amount of rotating mass.

For context that was prior to the November firmware power boost. Though we were on pirelli pzero racing tires (not as good as drag tires, but better than street.) Need to run the test again when the car is put back together.

Yeah, good point. Power loss is noticeable after 2 hot laps for me as well. Though I'm usually not starting at 100% SOC. And at 1700+ wh/mi the car gets below 75% pretty quickly, which is where power drop starts to kick in. Mountain Pass did some good dyno tests on this which you might have...

Correct, but more to it than just brackets and hats. Piston sizes have to be adjusted to match clamping force relative to the Model 3's master cylinder. I'll be using the 9660 or 9668.

Cooling hasn't been an issue with the Model 3, which really surprised me. But I've run it hard for multiple full sessions on 100+ degree days in the high altitude desert in UT. For reference, a few years back Acura brought out a couple of their then-unreleased NSXs for testing. They blocked off...

It's interesting, but I swear that thing has been available for preorder for like a year. We'll see if/when it is ever actually available. I'd love to switch so I can drop hinges and make fully detachable. And, will be cutting up b/c wing mounts need to be fixed to the frame. Yeah if you're...

They're the same. Essex is the only authorized distributor for AP Racing in North America, so Redwood is just reselling / dropshipping.
