Sorry, I meant "Spring Hat", the stock part they use to hold the top of the spring. The one that came with mine had a wider flange than the OE BMW part, so it rubbed when I set it to maximum camber. It looked exactly like the OE part, it was just wider, so it probably came off some other BMW. The replacement they sent was exactly the size of the OE part. The box the plates came in had the right part number, so they must have just made a mistake in assembling them.
