I have told everyone I know to buy shims this way. Local Steeler wants same amount for a single shim! Are you doing your own work to spend more money than you should? No, so don't waste money, buy something fun to add on your bike instead. I did record where I put each size since the numbers appear to be where they will wear off, so only one small, nay miniscule negative. BUY THESE!!!!!
I have only installed a few of them and those measured good to thickness and appearance was good. I have not ran the engine yet so the long term wear is unknown. I ordered multiple sizes to restock the larger kit that I have and they came in easily distinguishable separate bags.
