These dimensions are for standard Locost suspension with the axle centre line moved to calculate bump steer. 600 Wheel diameter - for this application the diameter is not important The track rod end is 63.3mm below the centre line of the axle so move the axle centre line down by 63.3mm to calculate bump steer 115 distance from top balljoint to centre line of tyre 177.3 distance from top balljoint to centre line of track rod end 114 + 63.3=177.3 95 distance from bottom balljoint to centre line of tyre 46.7 distance from bottom balljoint to centre line of track rod end 110 - 63.3=46.7 88 x coordinate of top chassis pivot relative to bottom pivot 188 y coordinate of top chassis pivot relative to bottom pivot 345 distance from bottom balljoint to lower chassis pivot 0 initial camber(degrees)- used to calculate length of top link 0 initial droop(degrees) - used to calculate length of top link These dimensions are for calculating driveshaft length for IRS 20 x coord of diff joint or rack inner joint relative to bottom pivot 36 y coord of diff joint or rack inner joint relative to bottom pivot 83 distance from centre of tyre to centre of track rod end This is the range of the suspension travel for the animation -5 top of suspension travel (degrees) 5 Bottom of suspension travel (degrees) These are just scaling factors .5 scale to fit display - larger numbers increase the size of the animation 200 movement speed - smaller numbers=slower
