Just saw this over at Dean's Garage (fantastic site in its own right, usually detailed stories on rare and unusual Detroit production and race cars). Detailed expose on design and development of Penske's TA Camaros, lots of info re. chassis/suspension design and setup, steering, engine, tires, etc. Some neat pix too, some I've not yet seen. Didn't extract and post, but here's the link, enjoy!!:
