Default Pad question: Has anyone run PFC08 front / PFC11 rear? Thoughts?

Car is a 2006 911C2S. Occasional DE car.

I ask because 08s for the rears are not available at the moment. Would there be any issues running 08 fronts and 11 rears?

i would not do it. 11's have a much higher initial bite and higher cf. this moves your bias way to the back, especially when you first get into the brakes.

I agree with DEADBEAT. I'd run Yellows all the way around if it is an occasional DE car. Or 11's all the way around if that is your only PF choice right now.

Result of brake pad imbalance induced bias. YMMV

I run yellows up front and blacks in back which is sorta similar. I’m intentionally trying to move bias to the rear though due to brake setup.

I run same setup yellow/black in my 08 997 track car no issues.

Thanks much for the feedback. Sounds like a split decision here. :P

More of a depends thing. The guys that use mixed formulations do so to fine tune the braking characteristics of the stock brakes.

my post was more a goof. the 360 in T1 was due to a large dissimilarity in torque between the front and rear brakes. In that case it was a stone cold fresh un-bedded set in front and a hot fully bedded set in back. For some reason the rears wanted to lockup far sooner than the fronts even started to bite.

Had similar in my 914/6 even with an adjustable bias valve, Went to Hawk Blues front and blacks rear balanced it nicely.

Yep. 100% on "it depends". If car has Hoosiers or slicks and a stiff enough suspension that won't upload the rear end too much during hard braking, then likely the car can benefit from more aggressive rear pads. It also depends on how the driver applies the brakes; late and hard or earlier and squeeze. Sorry, too many unkown variables for a straight answer.

If that is the OP’s only option then will have to try it and see how it turns out. One suggestion I have is bring a set of stock rear pads(or any pad that’s less aggressive) in case it doesn’t work out. I’ve done this before...
