That is all the info and p/n's I have for H&R spacers...
Conemasher - I'm unsure exactly what you're asking me.
I am sure that I would not use any spacer on either the front or rear without longer wheel studs.
You could fit a 5mm spacer in the rear with 5mm longer studs installed, but there was a chance I'd go with 10mm spacers, so I installed the 10mm longer bolts at the start.
