A few more things about the EF/DA vs. the EG chassis:

1. Unless you get an 88 or early 89 EF chassis with the seatbelts in the car, not the doors, the EG chassis can be lighter. Compare a 1990-1991 Civic STD to 1992-1993 EG CX/VX and the EG will be lighter. Now CRX HF? Well that's no contest if you get an early 88/89 one - they're stupid light.

2. If you want a track car it's very hard to get enough negative camber up front, and you can't run as low of an offset/wide enough wheel/tire as you can with an EG, unless you add fender flares
