B5M Stabilizer Ball studs/cups?

[Origineelreclamebord]

Hi everyone,

Recently I felt like trying a stabilizer on my B5M, but I really didn't feel like paying upwards of 25GBP for a set without knowing how it'd feel on the car. As such, I built my own stabilizer bars:





I've taken some spares from other cars , however next time I'd like to use the ball cups that fit onto the arms without mods. Anyone know if they have their own product number(s) or are only available as part of the kit?
