I'm considering adding Boothe 6mm & 15mm (f & R) spacers. Should I be concerned about reliability or other issues? I have done a bit of research but these seem to be the most commonly used. Are there better options that are also complete kits? BTW, this is daily driver use with no track.
Edit: questioning reliability of all spacers in general. Are there any issues I should be aware of?
