Might be about 15mm too wide, and far too stiff with the second leaf. It’s rated at 550kg, so 1100 for a pair, so maybe a factor of 10 too much… I’d be surprised if there’s anything even near 100kg on the front end of my kart, even fully loaded with my gangly self. If you can split that second lower leaf off, and then trim the remaining single down to width with an angle grinder in a jig then it may well work.
