thanks for the reply. where i bought them, it stated:
Item specifics
Metal Type: Aluminium Offset: 45
Rim Width: 8.5J Stud Diameter: 112
Rim Diameter: 18 Number of Studs: 5
Rim Structure: One Piece Condition: New
but someone said they look very much like 8J. I am very confused. will the springs be ok withouT the spacers for a while?
