I run the 11.75" rotors with organic pads in the front and 11x2.5" drums in the back on my 65 Cuda, ran the same combo on my 87 Diplomat.

They work great in both applications.

I am not, however, running 150mph laps at a race track, nor am I doing the quarter mile in 8 seconds.

And unless you are doing those things you do not need anything more than what I run. Unless you want to "name drop".

I'm not doing either of those, but will eventually hit the twisties for fun.

One thing I overlooked is that the caliper adapters he sells are for sliders and I have pin type so I would have to buy calipers. If I have to replace the calipers anyway then I'd upgrade to the viper calipers like the kits that I think Andy sells.

Ohh....so many choices. But that's a good thing I guess. I'll keep reading and make a choice eventually.

Here are the ceramic pads I bought for the disc conversion - pin-style calipers.
