do pads on all corners. if you just do fronts, you will likely end up with a bad brake-balance from the different compounds.

I've never had a problem switching pads on the same rotors. Also, a GM-supported racing team I deal with on occasion swears by bedding new pads on used rotors, and new rotors with used pads. Personally, I don't think it's that big of a deal, and you'll likely lay down a great transfer layer after you bed everything in nicely with some good, hard, fast stops, no matter what the changes are in pads and rotors.

 

Yes, that's a good idea when using the same pad compound. But the question here is about using different pad compounds. Sometimes using different pad compounds on the same rotor is no big deal, and sometimes it leads to issues. You just have to either try it and find out, or avoid it in the first place.

Probably 95% of the time, if you do have issues they will only be for the first track session or two. In fact, in my experience most of the issues actually work in the direction of the street performance being more spotty because of the track pad deposits instead of the track pad performance being an issue due to the street pad deposits.

 

would I be all right just swapping front rotors? or do all 4

I was thinking about running ar-2's up front and GTS in back and swapping the fronts to GTS for street/track. Then just swap front rotors

off topic. sorry. where's a good place to get ATE fluid at a reasonable price? also, do we really need assembly grease with track pads?

 

these work great with upgraded fluid change(slotted drilled cryoed with EBC pads)

 

Great on a track with no braking? I would not recomend Green Stuff pads for a track.

 

I use the same OEM rotors for street and track, and have never had a buildup of pad material (Hawk Blues, Cobalt VR&VX, Carbotech HP10 & HP12) that has lead to a vibration, or bad brakeing performance.

I replace my rotors every spring due to small stress cracks, not minimum thisckness.

I try to always get in a couple little drives before I load the car onto the trailer for a school, this way the race pads get to mate back up to the rotors prior to heading back out onto the track.

 

try this

EBC pads, not necessarily the green stuff, there are other pads better suited or dedicated for track use

 

I'm going to do my first track day in the s2000 on oem pads.I'm bringing a brand new set with me incase I have to change.There are different factors to consider if oem will be good enough for you though, are you running R compound tires? If so definetly get some better pads,are you familiar with the track? If not you will most likley not be familiar with the braking points and drag the brakes to long causing even track pads to fade a bit (lots of fade is directly related to this its not the pads its your inexperience at the track),is the track you are going to hard on brakes?I'm going back to Sebring and long straights are the brakes best friend.

Things to consider guys the oem pads on my AP2 will do me just fine at Sebring with Kumho MX's and being familiar in the braking zones.Also I do this for fun not to set a lap record.
