I usually order the Longacre kit. I tried this kit to compare the two. I found that the Speedway kit is superior in several ways. The Stainless-Steel flex lines have a 90-degree bend in them to help mount them to your calipers. Speedway gives you more straight lines than the Longacre kit. Better value all away around. I use these kits now exclusively.
