There are now block off caps being made if anyone is running slot mags that have too big of a center hole to put a regular Torq Thurst or US Indy mag style cap. I have a pair of Ansen slot mags that have a larger bolt circle for the center cap and dashman (
www.dashman.net) which he can be found on ebay user 68rrman, made me some caps to fit. These block off plates will cover 3 ¾” center hub hole and work great for 5 on 5 slot mags. Not sure how many Ansen wheels are out there with the bigger caps but anyone can adapt and drill holes to make these work on big hub slots. Just thought I would pass it along as I have had multiple sets of 5 on 5 with a big hub and never been able to run nice looking caps. The caps are 2 7/16" bolt to next bolt.
