You have a rwd that has the potential for high power, its not an easy car to drive fast, the gtr on the other hand is alot easier to handle in my opinion, i drove a std gtr flat to the floor on a track and thought it was sasy as, i cant drive my gtst flat to the floor without my full attention...
Dont just be proud of your gtst but know that its an entirely different car with its own abilities and attributes.
High powered rwd is the animal that bites back hard, it takes real skill to handle them
