Things like what? In my experience (at least with classic Mustangs) by removing power steering you have more room under the hood and the steering really isn't that difficult except when at a stand still. Fatter tires make it a bit more difficult too.

are there any current production Sports or super sport cars for the road that don't have power assisted brakes?

IMHO, it's all about feeling the car. As many have said previously, in a 2,200-2,500 lb car, don't see how you need such things.
Need to feel everything...every twitch, every fade, every sound or whatever and not be relying on secondary systems. But, everyone has their own preferences and I can respect that. These cars are like having a custom set of shoes or shirts made. It's fits you and that's all that counts.

7.5º of caster would be a bit much for manual steering. Power steering will also allow a smaller steering wheel and a quicker ratio than manual.

For track use... when you put too much horsepower and a lot of grip in a 90" WB chassis, it tends to get a little "sketchy" when trying to drive at the limit. I feel that I can stay ahead of the car with corrections, having a small wheel and a quick ratio. I don't think I would be comfortable at the limit with the slower response time of a manual rack and/or larger wheel.

Indy Car is one of the few hold outs that don't allow P/S even though all the drivers want it for the reduced effort. Indy Car's reasoning is that the teams would just quicken the steering until they were back to manual effort level anyway.

You are right on the money, I have power steering with lock to lock of 3/4 turn and a small steering wheel, I could not drive this thing with a manual gear because I either could not turn it or it would be way too slow. Front tires are 315x30x18 with 6.6 degrees of caster. Brakes are just fine manual,
I have tried lots of different calipers and rotors and all were easy to modulate with reasonable effort. When I first ran the car I had to throw the wheel and then catch it in order to move the steering fast enough to stay ahead of the car, power steering is worlds better.
