I will elaborate a little, I've just landed on a 2004 3.0 v6 x type jag.....40000 miles with a full jag history......I got it for buttons and fancy tastefully modding the suspension to drop it on its 18" wheels!..... Midlife crisis onset ?....I 'dunno!....anyway.....it would appear on the face of it fairly simple. New springs compatible with oe shocks, few spanners, job done!.....we be like Ali g at the next lodge meeting!.....is it really that simple or am I missing something here?......does anyone really know what they are doing?....
