I always reccomend slots.. .. most people buy crappy drilled rotors that are just that.. drilled.

A true 'cross drilled rotor' should be a cast rotor with holes... when you drill into a cooled/tempered piece of metal you're asking for cracks. This includes most brembos even.. they are not cast.

So anyway.. go for the slots.. on the street they will do you just fine.

Also get a GOOD BRAKE PAD.. I reccomend Performance Frictions R's. Most good autoparts stores carry them. If you cant them get raybestos.. stay away from those 'trick' pads.. they wear fast and leave major dust and are pretty worthless on the street IMO.

Far as getting the old rotor off.. since you dont care about it the BIG F'IN HAMMER gets it off just fine If i remember right the torque is 75ft lbs. .. but check your helms manual. I reccomend replacing those 4 bolts as they have a tendency to wanna ROUND after a while.. whats 5 bucks of bolts?
