Narrative:

Taking off runway 18C the tower asked if we could keep the preceding E170 in sight for a visual departure. We said that we could and we began our takeoff roll. At about 550 ft AGL we experienced an abrupt bank to the left approximately 40 degrees. Not enough separation between the preceding aircraft. Now that charlotte has opened the new runway departures on 18C have started to move pretty quickly. This has obviously been a benefit for the most part. However; the departures are getting closer together and wake turbulence off a previous departing jet is going to become a regular occurrence if there isn't more space given between aircraft.
