    Hi all got some discs in the post today and they seem to have a groove milled into the edge? My first thoughts were it must be for balancing reasons? But I thought I'd post it on here and see what you guys think?

    showed ur pic too my father in law (very good mechanic) and he said looks like when the disc was made it was slightly out of line so the chopped some to balance it up properly. he said to take it back..

    Just got the same discs from Euro, and mine had nothing like that on them... I would say drop em back to be on the safe side

    Seen loads from euros like that and never seen issues with people fitting them but if you feel uncomfortable with fitting them take them back.

    Nothing to worry about, standard procedure by manufacturers for balancing.

    That's just the balancing machining, no problem at all

    As said, pretty standard. You'd be more pissed if they forgot to balance them...

    Happened at the end of the warm up session on my last track day last month.

    Mad thing is I showed you that Westy and it was also another ECS disc set up..............not good me thinks?

    It was on Bens golf that is supposed to run at about 294bhp or something but is currently running much lower for some reason.
