How to install weight on kart

My kid is gearing up for his first race next weekend. I am planning to buy some 5 lb dive weights to get him in regulation of needs. Does anyone have a link to a video or some pictures with the best way to install these on the kart?

It’s pretty straightforwards. The weights are attached with bolts/washers that are flush typically to the lower portion of the seat back or sides. Sometimes you’ll see weight in front of the seat in floorpan.
I personally bought ribtect flush mounting hardware for mine.
Basically just drill a hole tthrough seat.

There are some general requirements for mounting. Your track may have additional, or different ones so be sure to check with them as well.

Here’s the general concenus:

  • Must be painted white.
  • 1x 8mm bolt per 8lb of ballast.
  • Sufficient washer thickness and area to prevent the weight pulling through the seat.
  • Must be double nutted and/or safety wired.

Oh and enjoy the race!! Report back and let us k ow how it went.

Thanks. Are you just drilling a hole through the center of the weight?

If it doesn’t already then yes. I prefer using flat headed bolts, called elevator bolt and then double nut with reg nuts. It’s like a carriage bolt but flat and about a 1” in diameter. That’s why I use double nuts with an impact. My local bolt place doesn’t carry them in metric so I usually get 7/16 and however long I need.
