when it comes to rear ends im clueless lol. well i got my car on the road about 3 weeks ago and have been taking nice and easy. Reciently i started pushing the car alot. well i noticed if i dump the clutch or step on it hard in 1st gear, ill only spin one tire. Now i have nitto 555r's on it and they grip hard but when they do spin, its usually only 1 tire. Why is this? any ideas? This may be normal but im just curious. Thanks guys
