1-2 weeks is in line with the end of Feb stuff we heard earlier this month(Speedtech also told me end of Feb or early March). My LHS told me their vendor would not have them for 6 weeks and that was 2 weeks ago.

Yeah even speedtech is on backorder. I couldn't even find a kit on ebay. Oh well I get the first one that comes into my LHS. When ever that might happen.

I really don't know. Just noticed a few people that had done it recently. Asking more for curiosity than anything else.

Eh you're right, the results shows the 521's as well, that's what I got, there is only a small difference between the single hole of the 521-1 and either on the 521. I used the inside on the 521, its what the fast guys at our track use
