Had some 944 ultras on my '13 then got some lowering blocks and tried to run them with the 944's but the bodies are too large, they hit the blocks so I got a set of 11.5" 412's to run with the blocks and it worked well until I put a chopped pak on. Now it bottoms a little too often. Has anyone used a block that will accommodate a 944 shock? If yes, what brand are they? Thanks.
