Have you met the Brassbolts brothers?  They're over in the Shimmering Flats, in Kalimdor, racing their rocket car against the goblins.  They usually win which is no surprise--the goblin car blows up so much it barely ever crosses the finish line!$B$BBut even then, the Brassbolts brothers are always looking for new ways to make their car go faster, and Wizzle told me he needs a very rare component for his next experiment.$B$BHe probably needs help getting that part.  Speak to him and find out.
