I guess I'm in the habit of over-simplifying the thought process because I gets weekly Pm's about either Matts car or mine. This includes guys running from 17 seconds down to 8's so to keep it as simple as possible I try to be as detailed as possible. Instead of stock suspension I say Caltracs, monoleafs, Rancho shocks, and 90-10 shock in the front. All bought used and broke in.
