Ok so i am thinking about replacing my front rotors with the combo slotted. drilled holes rotors, any thouhgts about them are they better than stock and how long will they last? and oh yea how do they resurface those kind of rotors :banghead:

They dont.
The advantage of slots and holes is that they dont fade under hard braking. What happens when brakes get hot is they produce gas (you can smell it after hard braking). This gas gets caught between the rotors and the discs which means less friction and then fade. Slots and holes in the discs allow this gas to escape so it doesnt create that layer in between.
If you arent experiencing fading or you dont commonly smell your brakes, you probably wont see any advantage to slotted or drilled.

They also cool a bit faster and give water a path to escape so the brake pads don't "hydroplane".
I'm with Ray on this one. Unless you're having some kind of "performance" problem, the slotted rotors are more expensive to buy initially and can't be cut.
Of course, you could go for the big slotted wheels that show the rotors and calipers, then use the slotted rotors for more of a "bling" look. ;)

The price seems good enough to give them a shot. Like I said above, unless you are very hard on your brakes, you probably wont see an improvement (any more than you would with any new set of rotors/pads) and you cant turn those rotors. Go for it and report back.
On a side note. If you do much mudding, drilled and slotted rotors are not what you want. They hold rocks and dirt in the holes and will tear up your pads in a hurry.
