This is an
ongoing debate at bimmerforums.com regarding the competitiveness of the E36 M3 in STU. The thread is long but there are many interesting posts spread through it, with several recent (p. 20 and higher) after Nationals. Keep in mind that the E46 M3 will be eligible for STU in 2009. Some of you cone killers may find it worthwhile, I know I do.
