Phone Eibach. Probably you will be ok doing them to Renault recommendations.Yes mine bolt to hub then wheels bolt to them they are eibach hubcentric 30mm spacers with steel inserts? But it doesn't tell me a torque setting. I would like to torque them correctly so I don't need to check them all the time worrying. All it says is torque them then drive for however many mile then re torque them. I just don't know what to torque them too??? Lol
With a wheel spacer that bolts onto the hub, its advised that you do it to the correct torque settings. Do it too tight and there potential of snapping them if driven hard.
