The issue with that is the other pad material left on the rotor when you switch. I've had issues where my pads and rotors kind of looked like the OPs (not quite that bad) when switching from street to race without a clean rotor.

One way to clean the street pad off is to just run the race pads on the street.. it basically acts like a lathe when cold and will do a pretty good job after a 100 or so miles of street driving. Then you are ready to bed in the race pads for optimal performance.

I've also heard of Carbotech's Bobcats. Supposed to be a street pad used along with XP series race pads and I guess due to some similarity in material avoids the steps listed above.

This is what I’m doing or will be next track day. I was switching between xp10/8 and stock and then found the compounds to not really play well together so now I have the 1521 for street but I haven’t switched back to xp10/8 since I haven’t had a track day since. Now I need rotors too cause I got some shimmy goin on, feels like the rear but I want 2 piece all 4 corners so I’ll run with it till I can replace em all.

Sorry to hi-jack, but if tracking on XP10 and occasional street driving, does the cold temp lathe effect remove that initial transfer layer? I guess what I've been wondering is whether I need to re-bed the pads after stints of short street driving and before track days? Thanks!

Probably not. I usually consider my first session of the track day to be the bed-in/test. More cognizant of how they are performing.. but they are usually on point after a couple laps (after the initial 'warm-up' lap). At worst, you'll need to end the first session a little early for fade..
I'd say to give it a shot without the added process of pre-track bed-in once and see how it works for you.

Ive never ever had this type of issue but Im sure it can depend on what pads you are switching between. On the front I have Mintex Extremes for the track and DS2500 for the street. On the rear Bobcats and XP8's. The Mintex Extremes have almost no stopping power until they are heated up so no good for daily driving.
