I've only owned f/r style cars (Mustangs,Camaros) before and when speed shifting my 5spd WRX I notice a bang as I hit 2nd and a little in 3rd. Is this because the tires don't spin? It also bogs slightly as I shift into 2nd. Should I lift slightly on the accelerator or slip the clutch a little? Coming off the line from a dead stop at what rpm should I dump the clutch and is that optimal for the best acceleration?
