Griggs Racing. No amount of playing with the stock style suspension setup will get you anywhere close. On Sumitomo HTRZIIs, I'm pulling 0.97g easily around roundabouts. Mustang II suspensions lack the anti-dive and the steering geometry, and just aren't as good as even a stock style suspension. The front and rear kit all in is about $10k. You can possibly save some money by getting your own coilovers, but I'm pretty happy with the Konis that come standard. You can get brakes from an SN95 for pretty cheap to fit the SN95 spindles that it uses, and you can use either an 8.8 or a 9". It uses a Fox body steering rack, but I'd recommend getting one from Griggs, not a "remanufactured" one like I did, which has a dead spot in the middle because they didn't replace the rack. You can save a little extra also by using a Panhard bar instead of a Watts link, but the Watts will outhandle the Panhard any day.
For autocross, I highly recommend focusing on the suspension setup more than anything else, and I can tell you that my '65 with Griggs suspension handles better than any car I've ever driven, save for maybe a Formula SAE car. Even then, that had Hoosiers, and the steering feel and responsiveness was very similar.
