Elliott was running SADDLE packs/Forward motor do you have the front hub spacer height, the camber link attachment point used on the front hub & the castor block angle used? Also at the rear inner camber link position. Was Bootsie running pinned or separate slipper? There is now a version 1.02 of the form that lists more options / location positions and is easier to navigate around, it's on Petit. Cheers Tony Rog I can't get on with the forms - they drive me nuts - I switched to windows 8.1 and since its like a nightmare - sorry hub on the shortest on the front - its not a lot! 2mm inside under ball if that's what you mean - I was running only 1. same on the rear inner - Boots = 2, me only 1mm un pinned - same for me
