Just finding the washers/shims to go between the caliper and the knuckle. I wouldn't say a real "issue" per se, but when you go looking for them, just take a micrometer/caliper with you so you can be sure how thick the ones you are getting. He calls for 2x 2mm shims on each bolt between the caliper and knuckle, and I ended up only having about 3.7mm with two washers/shims together, so I'd say his measurement for 2x 2mm(4mm total) washers doesn't have to be exact. Just in the ball park. I'd say if your shim was 4mm +/- about .5mm then you are probably good, but of course take your own measurements just to be sure, I don't make any promises. I've got plenty of clearance on both sides of the rotor at 3.7mm of shim. With no pads installed just make sure the rotor doesn't contact the caliper at any point.
Also just so everyone else has a ball park figure for machining, my local machinist charged me 65 dollars per rotor to make them fit. and he did a great job. I'm sure if I shopped around I could have saved a few bucks, but I don't live exactly close to town, and this machinist was the closest to me, so I save the money in gas I suppose.
Also, if I was to do it again, I would just give the machine shop the bolts for the caliper and have them make me some 4mm shims out of some stock so you don't have to deal with two washers on each bolt for shimming, and it makes for a neater install. Just my extra to add to it, I guess.
BTW, I'm running a 17x10, 0 offset steel wheel, and I had to order wheel spacers at least 8mm thick in order to clear the caliper. I went with a 10mm just for extra peace of mind as well as longer 10.9 lug studs. The calipers clear the inside of the wheel just fine, but the part of the wheel that hits is where the "spokes" meet the center of the wheel, near the lug holes.
