yea studs were included…mine where the type that u actually replace the stud in the hub…but H&R also make a type where the new stud is pressed into the spacer then u bolt the spacer on using existing studs…so essentially they are just putting a stock stud into the spacer then bolting the spacer on using existing studs…i like nmy set up better because i dont feel bolting spacers on is a good idea but actually replacing the studs with longer ones is better…FYI i have 20mm spacers milled down to 16.5mm…also on most cars anythign under 10mm thickness dont need longer studs…but over i woujld advise…i think the market is there from anythign from 3mm-10mm…again i had a rare case where my offset sucked on my wheels and needed a large spacer to clear my huge brakes
