What are the benefits of running a 2 in drop spindle on a street stock, specifically a 79 camaro on an ashphalt track with 12-14 degree corners. Any and all info would be of help. Thank you!

In my opinion all the difference in the world. It changes ride height without causing a-arm problems, greatly effects bump steer. etc . In one sentence it levels out a-arms and tie rods. our car went from middle to front with the other changes that go along with it.

A 2" drop spindle will help your car turn much better through the center of the corner because it re-positions your moment center(roll center) to a much better location.  You should also get better forward bite on corner exit because you will no longer have a tight/loose problem.  A note of caution though, if you make this change, you need to make sure you do not have excessive bump steer or ackerman.  If you do not correct these problems with the steering, it will cancel out all of the positive changes you made on the moment center.  Also, don't run too much front spring split(RF stiffer), or it will overload the RF tire and cause you to have a push in the center.  Start out with the RF spring 100 lbs. stiffer than the LF, at most.
