Hi guys,

I bought aftermarket rotors but I got sent rotors which were the correct size (348x30), but they were too deep, which meant they didn't fit and couldn't turn.

I noticed afterwords that it said 745i on the package... So I was wondering, eventhough the size is the game (348x30), de depth is different. Does the 745 E65/E66 use different sizes?

What are the exact differences?

Thanks in advance!

 

Its the hub thats different and also how the caliper mounts on thier suspensions. Same thing happens on M5 vs Alpina same size disc but hub is off a few MM
