Looked at my rotors and at least one needs replaced due to rust. OEM or aftermarket for replacement? Cheapest I found so far with OEM is 48.00. Anyone have a suggestion?

 

Good wire brush on a drill or a 3M scuffing pad on an air grinder would help if it's just rust and not warped.I've cleaned up plenty of these to get them back in usable condition. If you change only one out I'd go with oem as sooner or later the other side will need to be replaced and you might have trouble finding the same aftermarket one. Plus braking effect may be different with different or only one new rotor? When ever I found one that was in bad shape or warped usually the other side wasn't in too good a shape either. If aftermarket is your choice I'd go with a pair of rotors.Same as you'd do on brake pads. Here's one suggestion. 1995 1996 1997 1998 Polaris 500 Sportsman 4x4 Front Brake Rotor Disc | eBay

 

This looks more than just surface rust. I don't think it can be turned out and still have enough depth on the rotor. It looks like the previous owner let it sit for an extended time and water leaked on the rotor.

 

Mine is solid will the slotted ones make any difference

 

slotted wont hurt, if anything it will keep the rotors a bit cooler....not that u would notice really...

 

Should be lots of rotors on Ebay for cheap. My cousin bought the whole strut, spring with hillary hub assembly for $50. The Rotor should be no more the $20 for a set.
