Yep, got a manual trans, it does make a big difference how long they last. Even have a set of PF pads in my garage and I'll eventually purchase the rotors. At work I do alot of driving through sand and gravel. Sometimes it gets up in between the rotor and backing plate, making a horrible squealing noise. If I had slotted or drilled, I'm sure those small rocks would get hung up and do some damage to the pads. When I get around to installing the manual hubs, I'll probably go ahead and swap out the rotors and pads, then keep my old one's for spares.

I won't let anyone take my wheels off, every shop that has done it in the past really over-torqued the lug nuts. All I use is the factory lug wrench and hand tighten them, never had any problems, nor have I lost any lugs. If you do have a shop do any wheel work, I'd recommend taking off the wheel locks before bringing it to the shop.
