Changing EBC green to yellow, must scuff rotors?

[Heysie]

I'm going for a track day next week and running now with EBC greens. So I want to change the fronts with EBC yellows. Do I need to scuff the rotors?
Thanks

Any time that you replace brake pads it is not a bad idea to mill the rotors even if they are not warped. Just one or two thousandths just to get the old pads residue off your rotors. EBC recommend this as well if I am not mistaken. Someone correct me if I am wrong but I learned this when my friend who is a mechanic showed me how to replace my brake pads.

I don't know what you mean about "scuff" the rotors but it would be a good idea to bed the pads REAL good since they're race pads. 10 60-5 mph and 4 80-5 mph stops should be OK.

When changing mine from street to track to street I use a 3M pad on a drill to scuff the rotors ( I do this with the rotors on the car). Then I lightly bed them in (4 medium petal pressure slowdowns from 60mph to 20mph) and let them cool completely before going on the track.

Thanks, I've scuffed the rotors and going to bed in the pads now.

FYI, the yellows take a bit more to heat them up to proper temps. When they are cold, they are not as effective as the Greens, so make sure you are careful if you are driving to the track with the yellows already on the car. I run the greens on the street, and yellow on the track, and love the EBCs.

Both Tom Glenn and Jay Lopez are right on. The EBC's in ALL performance ranges, including the racing BLUES, are also very easy on your rotors. Unless a weird circumstance has happened, your rotors should not be significantly "scored" enough to require surfacing when switching back and forth. A simple scuffing as Tom described should be sufficient. And...... Tom should know...... having already won a Super Stock Viper Day's season championship on those YELLOWS. Thanks Tom.

If I remember correctly, Jay's car runs a complete Dilusi setup, with Wilwood calipers all around, and the EBC's work just the same on those and all the other aftermarket applications.
