As of late this morning, all backorders have shipped. I greatly appreciate everyone's patience as we adjust to the high volume of orders and new production methods.
Many kits are close to being in stock, but still have a few pieces left to be complete kits. There should be inventory of most kits by the end of the week. While the site will be updated with inventory as it's available, some customers have found issues with the site saying that items are on backorder when they are really in stock. There are some problems on the backend of the site that I'm looking into, but I don't have a timeline for repair.
If you're waiting on a specific kit to be in stock, please send me an email and I'll check for your specific case. Otherwise, it is safe to assume that all kits (except the offset kits) will be able to ship within a week. Thanks!
