Um, there are HUGE import meets every Friday night at 11 mile and Inkster roads. Redline Motorsports is usually the ones to organize the meet spots.
www.xceedspeed.com is probably your best source of information for local shows and meets and as soon as I find out about them they go up on my site too
www.MichiganCivics.com
there is also a meet that I started at Flexivity in Southgate every Tuesday nights.
