Slotted/Drilled rotors, adversely affected by salt?

[wkmpt]

Thought this would be the appropriate forum, since a rotor is a rotor, right?

Need to get some new rotors purchased and installed for my cage before the winter kicks in, was looking at slotted and/or drilled rotors. Since they salt the streets around here, was wondering if a buildup of rust in the slots/holes might pose a problem.

Thoughts?

Well, no, a rotor is not just a rotor....
Bike ones are usually either stainless or a semi - stainless which don't usually have corrosion problems.

To my knowledge most car rotors are Iron - nodular or plain - which has quite a severe corrosion problem. If I was you and had to have either slotted or drilled rotors I'd go for the type with surface grooves rather than through holes as the grooves will stay cleaner hence less likely to corrode.

What sort of kit are you buying

these here are stainless http://www.summitracing.com/search/...Stop-Slotted-Rotor-Upgrade-Kits/?autoview=SKU

pricy but if improved performance is your desire then price is not the prinicpal factor in your purchase.

I've got a set of PFM ductile, nodular if you prefer, iron rotors on my bike. Love the way they stop but rain and moisture make a mess of them. Riding in the rain makes a mess of the pipes and the front of the engine.

Ah, I had forgotten about the whole iron/stainless thing...

Yup, the rotors I'm replacing are all iron, vented rotor in the front and solid rotor in the rear.

I think I'm going to look for the slotted rotors that are a groove and not slotted through the rotor.

Jeez, those kits look sweet, and the price is damn competitive also. Doesn't look like they have them for my Bimmer, however...
