They work on quite a few unusual/performance cars, a couple of the hapshire jap car club use them too I believe, always seem to be Subaru's and Nissan S14 / 15s around, when I had an issue with my last car ( my clutch turned it's self into very small pieces) I literally broke down outside, the manager took my car in, diagnosed the problem (and quite a few others I was compleately unaware of), and stored the car for me in the workshop overnight till it could be low loadered off in the morning, and wouldn't accept a penny for it!
I'm going to be booking the Z in for new rear drop links, and a brake fluid change shortly so will let you know how the Z fares there
