there should be the 4 washers (labled 6 in the picture above) between the big washer and the plate. The washers that came with mine were 1/2" rather than 14mm. 1/2" won’t work since they don’t fit over the strut. If thats the case, I’d contact your supplier and ask for the correct washers.
As others mentioned, I couldn’t get max camber using the four bolts, instead I’ve settled for lesser camber, but still using four bolts.
