I'm about to do a brake change and I have a question on slotted rotors and mud. I've never had any experience with slotted rotors on an off-road vehicle.

Do the slotts fill up with mud? I can't help but think that they would and that it couldn't be good for the pads.

I'm looking at purchasing either the NAPA Ultra Premium Rotors or the NAPA Hi-Perf Rotors. Are the Hi-Perf even worth the extra $26? Or should I just stick with the Ultra Premiums?

My KJ obviously doesn't see any track use, but I frequently tow and off-road. I also live in the mountains, so I do a lot of mountain braking. Just wondering if they would provide any benefit. However, if they cake up with mud and ruin the pads, then I'm not interested.
