So I did one side of the Koni Yellow rears yesterday. Couldn't finish the other side as it was getting late. Anyway, one of the steps required is drilling the rear top hat. Koni says we should drill a 12mm hole. I don't have a metric set and I read somewhere that a 1/2" would work, so I just went with 1/2" without thinking of trying anything different. 1/2" is 12.7mm, so pretty close, the hole will have a larger radius by .35mm over the Koni shaft.

After reading more about the Konis this morning, I realize a few folks are going with slightly smaller bits, going with 31/64ths (12.3mm) or 15/32nds (11.9mm + some slight grinding/boring). Now I'm questioning whether the 1/2" bit was too large. It didn't really occur to me that the top hat would have any side load from the strut's shaft that would require an exact fit. I figured the hole was there just to get the thicker adjuster through.

Anyway, what I did has been done and there is no turning back on this top hat, but I can certainly buy another if I had to. Need some input on whether this should be a problem or not. Also would like to hear if anyone else has done 1/2" and what their experience has been. Car seems to drive just fine, no weird noises or anything, but want to prevent any future problems.

Thanks.
