Go kart steering measurement tool for measuring a caster angle of a front wheel steering mechanism of a go kart, comprising: a tool body, and an axle engagement structure adapted to position the go kart steering measurement tool on an axle of the go kart, with the axle engagement structure having an engagement groove or a tubular channel, wherein the tool body has a target surface for making an impinging laser beam from a separate laser emission tool visible to a user of the go kart steering measurement tool, wherein the target surface is a planar surface and comprises a first scale, comprising a plurality of first markings, and a second scale, comprising a plurality of second markings, with the first scale and the second scale having the same scaling, and wherein the first scale and the second scale are spaced apart, such that, upon the separate laser emission tool being attached to the front wheel steering mechanism and the front wheel steering mechanism being turned and the impinging laser beam moving across the target surface as a result thereof, a first measurement on the first scale and a second measurement on the second scale can be made by visual inspection, with a difference between the first measurement and the second measurement being an indication of the caster angle of a steerable stub axle of the go kart, wherein the axle engagement structure is adapted to position the go kart steering measurement tool on any one of a right steerable front stub axle and a left steerable front stub axle of the go kart, with the target surface positioned in a plane that is orthogonal to the one of the right steerable front stub axle and the left steerable front stub axle and facing towards the other one of the right steerable front stub axle and the left steerable front stub axle of the go kart, such that, upon the separate laser emission tool being positioned on the other one of the right steerable front stub axle and the left steerable front stub axle of the go kart and upon the steering mechanism being turned and the impinging laser beam moving across the target surface as a result thereof, the difference between the first measurement and the second measurement is an indication of the caster angle of the one of the right steerable front stub axle and the left steerable front stub axle, onto which the go kart steering measurement tool is positioned. a tool body, and an axle engagement structure adapted to position the go kart steering measurement tool on an axle of the go kart, with the axle engagement structure having an engagement groove or a tubular channel, wherein the tool body has a target surface for making an impinging laser beam from a separate laser emission tool visible to a user of the go kart steering measurement tool, wherein the target surface is a planar surface and comprises a first scale, comprising a plurality of first markings, and a second scale, comprising a plurality of second markings, with the first scale and the second scale having the same scaling, and wherein the first scale and the second scale are spaced apart, such that, upon the separate laser emission tool being attached to the front wheel steering mechanism and the front wheel steering mechanism being turned and the impinging laser beam moving across the target surface as a result thereof, a first measurement on the first scale and a second measurement on the second scale can be made by visual inspection, with a difference between the first measurement and the second measurement being an indication of the caster angle of a steerable stub axle of the go kart, wherein the axle engagement structure is adapted to position the go kart steering measurement tool on any one of a right steerable front stub axle and a left steerable front stub axle of the go kart, with the target surface positioned in a plane that is orthogonal to the one of the right steerable front stub axle and the left steerable front stub axle and facing towards the other one of the right steerable front stub axle and the left steerable front stub axle of the go kart, such that, upon the separate laser emission tool being positioned on the other one of the right steerable front stub axle and the left steerable front stub axle of the go kart and upon the steering mechanism being turned and the impinging laser beam moving across the target surface as a result thereof, the difference between the first measurement and the second measurement is an indication of the caster angle of the one of the right steerable front stub axle and the left steerable front stub axle, onto which the go kart steering measurement tool is positioned.
