This article adds new knowledge on the ways that car modifiers negotiate their cars in elation to design, power and performance as qualities that make cars attractive. Inorder to understand the complex ways in which masculinity and cars co-constitute asculine subjectivities and communities, the article uses the modifier-car as a tool to discuss how certain ways of modifying and personifying cars create links between masculinity and cars at risk in male-dominated communities. Despite the fact that modified cars may share the looks and sounds of typical racing cars – and therefore appear to encompass some of the most convincing elements of power in automobile systems, namely the capacity for risk-taking – it is rather an alleged lack of power ascribed to some versions of modified cars –the plastic rocket–that stand out as a risk to constructions of modifier masculinity. Viewed as a feminized car, the plastic rocket has come to be negotiated as an inauthentic, foreign, powerless and vulgarexample of modifying cars compared to the Swedish modified car community’s working-class self-image. At the very core of the plastic rocket is a threat to modifier masculinity which is the inability to back up one’s looks with strength. It is argued that the discourses formed around the plastic rocket indicate ‘queer’ possibilities in the ways cars extend male bodies.
