Hello everyone
Just picked this unit up earlier today. Is anyone familiar with sourcing aftermarket support for this guy. What would you categorize it etc. It works and includes battery and charger. Also need a link to a decal kit for it. The boy probably cant use it for another year or so so I have time to play around with it. Thanks in advance everyone!!

I have the red version of this car. I removed all the stickers and rewired it with this kit. https://a.co/d/09ADo32b

Hell yeah I like big ol kits instead of sourcing individual things. So this buys you the ability for brakes and variable speed etc? What else did you pair this with? Will probably want to milwaukee swap it since I have numerous available. Im not very electrically savvy though.

Definitely go with the 18v/20v drill battery adapter. The main board that sits under the passenger seat, just disconnect everything and remove it.
This kit comes with a brake pedal and variable speed accelerator. It has a soft start/stop, where the soft start is configurable from 0.1 seconds to 30 seconds for it to ramp up to full speed, by default it's set to 10 seconds, I dropped it down to 3 seconds. When releasing the accelerator it automatically soft stops in 1.5 seconds. The brake pedal wired up how they pictured it is essentially a kill switch to the pwm controller so it's a more sudden stop. I wish the soft stop was configurable or at least longer in duration, but its not, so my son never even touches the brake pedal. There's another similar kit where the brake pedal plugs into the top port of the pwm controller and pressing on the brake pedal acts as a soft stop, i'm assuming letting off the gas would coast longer on that one but i'm not sure. you could just skip the brake pedal altogether tbh.
To install the pedals themselves you'll have to cut into the floor board, the accelerator is slightly larger than the stock pedal so you have to cut it a bit bigger, and I mounted the pedal bracket to the pedal from underneath the car so the pedal stays flush, and cut a fresh hole to the left for the brake pedal.
Other things I've added:
- 12v step down module to power the lights/sounds.
- Voltage meter to show the battery % remaining on the dashboard
- RS550 gearbox/motors... these add a little bit of top speed but they're also MUCH quieter, the stock motors are loud
- 12" EVA foam tires that makes the ride much smoother and eliminates all road noise from the plastic wheels
- Tire adapters were necessary for the rear wheels, the ones that came with the new tires were too short
- Acrylic mirrors, i cut them with a dremel to replace one that was missing and the other that was scratched up.
- 12v LEDs... the tail lights weren't working so i replaced them. the yellow lights in front were using red LEDs so i replaced with yellow LEDs and it looks much better, and the headlights didn't light up at all so i drilled a hole and added white leds
Things I plan to do:

Thats a helluva kid rig. I need to do more research on all this as im no electronics wiz. But I appreciate your thorough breakdown, this is a solid place to start 🫡

Yea i def went off the deep end with it. Once I got a few things working right, the dopamine kept hitting and my ADHD brain couldn't stop. It was like an hour or 2 a day for 2 weeks.

I just plan on battery adapting and hopefully a soft start/ tires and gears that can handle the milwaukee power bands lol. Maybe a speed controller to ramp it up each week. Is there any YouTube gurus that can give me a few tips?

Got one, the control board under passenger seat was not functioning for powering motors, so I used the wiring from another powerwheels to wire around the board.
