Yeah Scott, what Garry said.
It's called a RWD V8 powered car with a light ass rear end. You just have to take it easy man. Believe me, I know what the urge is like to floor it as you're making a turn, or starting at a light. You just have to try to calm down, and save that stuff for big parking lots, or the track!
Do you have LCAs with relocation brackets? If not, I highly recommend them. This might help a bit, but like previously stated, just apply a little less pressure on the pedal.
