I am currently runnging rs29. The brakes are very smooth but do not have much intital bite. I had some issues running Road Atlanta this weekend. And yes I am running high temp fluid. Brade fade was not an issue but the car just requires too much peddle pressure to stop it. Any one used these higher CFriction pads? thanks

 

RS 14 is black. it has more initial bite than RS29
very few uses RS15, not sure you will get much real feedback.

 

thanks mooty - I am going to try RS29 fronts and RS14 rears and see how those feel.

 

I started on yellows (4-5 sets) then switched to rs-14 all around on my '07GT3 until I got rid of it. Outstanding bite compared to yellows. Once you go black you never go back. Only downside is they wear out quicker and eat thru rotors faster.
