I have had issues with every TC that I owned that had toe set with pills in a block, mainly it is the block. When screwing in the block it gets slightly pulled one way or the other, every car I had did this. You have to find the right way of tightening the screws for the outer and inner blocks. If I remember correctly, it is more on the inner blocks than the outer blocks that cause the issue. I remember struggling with this, then another guy looks at my car and unscrews all the blocks, then screws them in a weird order and it was dead nuts on. Then I did it my way again and it was off. But if you want to get rid of the issue all together, jump ship and come drive what I drive now, lol.
