ECS is currently having a sale and their Geomet slotted rear brake rotors are 50% off. I machined my front rotors last week and measured the rears and they were about .015" under spec, so this is a perfectly timed sale! I'm just wondering if it's necessary to replace anything else while I'm there. Should pads be replaced? Should front rotors be done too?
Pads should always be replaced when rotors are. Also it's a good time to do some maintenance of the calipers and suspension parts

I know they only do 20-40% of the braking, but they're on sale so why not. If I had the money I'd do the front too, but I don't and they are not the ones under spec. I'll see about doing my pads. Thanks!
If it's deal go ahead. Old pads will destroy rotors pretty fast so make sure the pads are new or smooth
I've got a wilwood big brake kit on my fronts and stock rears
I'm planning on getting the same rotors for the front and EBC Redstuff pads. I guess I'll just get OEM pads for the rears? I was going to get the EBC rears, but I guess it's not necessary. I'd like to keep the dust down though since I've got those white R85's.
Ok, so getting the EBC pads and ECS rotors would be about $170. I don't really want to spend that right now so I'm wondering if it is actually necessary to replace my rotors at all. They are .015" under spec. Will continuing to run them present a big safety concern, or can I get away with it for now? I don't really want to miss out on the sale either though...
.015 is a very small distance, its about 2 sheets of paper. while you should keep this in your mind and replace them soon you can still use them for a little while
I just want to take advantage of the sale. Will running new rotors on pads that have ~80% life left damage the rotors quickly? If it's necessary to replace pads even when the pads I have are fairly new, then I'll just hold off.
if the rotors you currently have, have any witness lines or grooving, the new rotors will gain that very quickly, if they are nice and smooth, the new rotors will be nice and smooth. but it all depends on what is harder. the harder item will wear the softer item

I went ahead and ordered the rotors. Figured I was being kind of stupid; there's no need to put them on immediately so why not grab them while they're cheap(er). I'm just going to hold off on installing them until the pads need replacing since my old rotors are not totally smooth.
