Winter driving on drilled and slotted rotors?
Has anyone driven in winter before with drilled and slotted rotors (such as the E63)? I wonder if the dirt and snow would clog it up and affect braking at all. I suppose the majority of stopping power comes from the brake pads, but it’s a random thought I had.

the key to winter driving is to slow down and drive according to road condition. Therefore, no matter if it's drilled, slotted or ordinary disc, you should be able to stop in time. IMO.

Good point. I think I’ll be in comfort mode with traction on for the better part of winter. Except for empty parking lots lol. I just wondered if drilled rotors get clogged with grit, requiring frequent washing or not.

Even if the holes are clogged up completely, you have the same functionality of basic rotors. You aren't tracking the car in the snow so it's a non-issue. Besides, the brakes are too warm, they cook off anything. I usually see them plugged with rust in cars that come from up north.

Anyone have any tricks to keeping snow out of the tire treads while driving in snow? I'm thinking white lithium grease or even easier... pam cooking spray ... every stoplight I'll get out and brush off the tire snow and then spray down the treads.
discuss.
discuss.

Lol so we discussed with your mom and she suggests you could try her KY...apparently she’s got buckets full? :p Seriously though, I get it now, thanks. Clogged rotors would make no difference to braking efficiency. See, I’m learning new things on this forum (as are you, Peter?)

I've had drilled and slotted rotors on every vehicle I've ever owned and I've lived in Philly, Colorado and Chicago... Never had an issue. In theory your slots are going to help throw the "trash" away from the rotational axis. That's kinda their job. IT'll be fine dude

I'm sorry you're taking such a ribbing, clearly this must be your first "supercar." Take it out in the spring (look out for standing water and ice), and really stretch the automobile and your limits. I think you will find that reasonable caution will cover you in extreme winter driving, the same as it does in a milquetoast vanilla auto. Be careful, have fun when there are no other cars are around, learn your platform and it's and your limitations.

yea its not an issue.. granted after some tracking they get filled up with brake dust and get some tiny fractures.. but its fine..
