Our Track pack has everything to get you started perfect for hobby racers, includes one Speedsocket tool and a set of BRE4140 Nuts.
Do you have longer wheel studs? We now have the Extended BRE Nut option, each nut is counter bored to allow +10mm maximum of wheel stud to protrude from the end of the nut without it picking up the next nut in the Speedsocket. 
We have 5 & 6 stud options, Current Threads available M12x1.25, M12x1.5 & 1/2-inch UNF
*Extended nut option not available for 6 stud applications, don’t use Extended variant on standard studs that don’t protrude from the nut as the nuts have -10mm counter bore at the start.
