If you are able to provide or correct any information on springs, please do so in this thread and I'll try to keep this updated. Also, if you feel other information should be added, please suggest.
If you have side-view photos of your car, preferrably on stock wheels and tires, please post them here and I will add them as well. If you have aftermarket wheel or tire sizes, please post those as well. Again, stock wheels and tires are preferred for comparison.
