I run the ProCar Scat seats. They are as comfortable as a modern day SRT seat. They are high bolstered, and definitely hold you in place.
I bought the seats and the floor brackets from Summit. I am only disappointed in the adjustability/Dump feature.
They are a b!tch to slide forward, and they do not dump forward worth a damn.
other than that, they rock!
I am thinking about going with a modern Challenger rear seat cushion and back though....
I'll try to post some pics another time.. My computer/photobucket is acting up..
