I used this on the A3, probably even less sophisticated than leaf springs but works rather well, the spring has a natural side control and allows the axle to rock as well.
Really does need a good clean up under here
The spring was fine until I opened a bottle of Carrs near by, within hours all my needle files and anything steel went rusty, can only guess it was from the open bottle fumes as I've never experienced this problem whilst using safety flux
