i was wondering who makes a good set of lowering leaf springs

thanks

You might want to do a search on springs in the 'Brakes & Suspension' forum - there are lots of good posts on spring manufactures and suppliers.

Here is one good post - http://www.camaros.net/forum/ultimatebb.php?ubb=get_topic;f=7;t=005338;p=3

Hope this helps.
