Club RSX and Honda-Tech seem to have a good following locally for the strictly import crowd.

If you're not a poseur and don't mind hanging with some big dogs www.Crossroadonline.com is the place to go. Really good bunch of people that get together regularly for meets, cruises, shows and track races. Another big dog group is www.racersden.net. They are mostly Stangs and F bodies but some imports do hang with them also. A good bunch of people also. They meet every single night. Don't cop an attitude with either group.

Edit: www.terrepin.motorsports.com is hosting a meet 11/08 at UMCP lot 4j. Probably a lot of clubs gonna be there.
