Hi Pablo,
Spigot rings no problem, £5 a peice, if you bought the GTR's new and didn't get them then obviously they should have been included though!!
Black wheel nuts we don't sell any more BUT we may have a few knocking about, is it the 19mm socket nuts you're looking for?? Would be £1 each as per the regular nuts.
25mm spacers are alloy.
Obviously with steel studs, nuts etc
