Didn't bed them because I was worried about screwing something up. I look at the rotors and looks like a single line of wear near the outer edge of it.. near where the retaining clips the pads slide into are. This is on both sides.
Porterfield R4 (and R4s) Race Compound Brake Pads
We'll have Porterfield pads for our FiST soon!
Porterfield is very open to making new pads for nearly any application. They're a friendly group, easy to work with, and local!
In the past I've had new pads made based strictly on description and an outline sketch (sent by FAX or email). Those pads worked pretty well, but I recall having some minor fitment issues at least once.
Since I wasn't in a super hurry, I decided to mail them my used pads. Hopefully this will result in a higher quality product for us.
They can make either the R4 (race) or R4S (street), but I asked for R4, first.
I'll share an update just as soon as I get the pads! At this point, I think this may be later next week.

The heat shield was my first idea. Will have to trouble shoot tomorrow.
Noise is part of the deal with R4/S. If the sound is uniformly coming from all corners, it's probably normal. Their batches can vary, and I've had noisy and mostly quiet experiences.I need some help here. I just installed the pads and went for a low speed drive to test the breaks. Now I have a horrible scraping sound with driving all the time. Not just with break applied. What is going on or is this normal? Thanks. R4-s pads
The appearance of uneven wear is typical. Once you bed them, you'll see it even out. After my first track day, it was perfectly even.Didn't bed them because I was worried about screwing something up.

That's a quick job, and worth doing if you believe there's possibly something amiss.The heat shield was my first idea. Will have to trouble shoot tomorrow.
I'm betting you did it right, and won't find anything wrong.
The incredible gains in power here aren't free. You pay for it with a noisy and dusty pad! It's why I'd just swap the pads at the track and stick with R4 race only. Depending on your style and expectations, the street pads may let you down.
Okay. I'm going to share my idiot experience with you. Many of you may relate. To set the stage... I had to sneak out while wifey was watching TV and baby was napping to change the pads. I'm rushing along and all is going smoothly until... "When are you gonna be done... I need you to watch the kids... I don't feel well and I have to get dinner ready". I proceed to rush the job, put a pad in backwards, and break a bolt. I fixed the bolt and finished up. The sound I was hearing was the wrong side of the pad rubbing the rotor. I always thought I was never dumb enough to make such a mistake. The moral of the story is wives make you dumb.

"When are you going to be done" is my wife's favorite phrase.
I did that once a long time ago after rushing to swap my street pads back on to drive home from the track. 
Glad you got it figured out.

This story made me smile, thank you for sharing. I agree, this is your wife's fault, not yours!Okay. I'm going to share my idiot experience with you. Many of you may relate. To set the stage...
