|April 15, 2008 - The back of the car sits quite high.|
You can see it in this picture. And this might be the reason. These shackles are very obviously aftermarket, and a quick query on the MG Experience forum (a very helpful bunch) returned the information that the length between the holes should be 2.5 to 4", not the 5+" I have now. If I flip these around and use the bottom hole as the top, I'll get a good idea of if that's too long or two short. It's a distance of just over 3".
I'm guessing a previous owner did this in order to raise the rear and hopefully stop that tire/fender interference.
