the originals are heavy duty and a grt rotor...but most folks like the look of the slotted/drilled rotor...but they come with problems if they aren't done right...prone to cracking, etc...our stock rotors are top notch...I went to drilled rotors all the way around, more for looks than performance, since all I do is drag race for the most part...updating your lines to steel, and your fluid will do a lot more for prolonged braking, and I went to ceramic pads vs our stock pads...just shop smart...but do upgrade the lines and fluid to take full advantage of your purchase whatever that may be...
