I picked up a lightly used set of cobalt XR4 pads for the rear to use for the occasional track day. I was hoping to pair them up with a set of XR2s for the front. Do you think there would be an issue with running the dtc60s in the front with the Xr4 in the rear???

I'm trying to shave some cost since i have had to buy a second race harness, installation hardware, and a helmet.

 

Mixing pads and compounds is very common to reach your desired brake bias or feel.

See my PM.

 

running Hawk HPS up front and mazda stock pads in the rear.

 

Curly to the rescue. I now have track pads, and I don't feel guilty about it. I still can't decide if I should have bought a helmet or just rented one. Zamp SA2010 for $169 before 10% off and free shipping. BUT, I suppose that is another topic.

 

I have ULTs in the front and OEM in the rear...wish it was the other way around

well, I wish I didn't ruin my HP+s there were in the rear.

 

With a 1.6/1.8 rear mixup with the XR4s i had to regroup. I have ended up with porterfield rs race pads in the front and carbotech xp10s in the rear. Thanks to those that allowed me to by their sloppy seconds in an effort to have a set of dedicated track pads for my occasional trip to Barber for a reasonable cost.

In case you want to see the track from behind the wheel. Here is a demonstration lap from the Porsche driving school.
