I've been watching the American Le Mans race at Mid-Ohio today. They've shown many in-cockpit views from many cars, including the GT2 Porsches. I watched intently, studying how far they were turning their wheels.
The LMP cars appear to use about 150 degrees of steering. The GT2 cars use what appears to be exactly 200 degrees: I never saw any of the drivers turn the wheels more than a little past 90 degrees from center.
Sure, true stock production cars on really tight courses would use more steering. However, I did not buy GT4 to simulate the driving I do in my boring little Accord every day, so its hard to understand why 900 degrees is necessary.
200 degrees simulates race car steering. That's what I bought GT4 for. For me, 200-degree wheels give me exactly what I want.
Dude, you TOTALLY missed the point of my post, or you didn't read it at all.
Its not just about how much you can turn the wheel, its about how much the front wheels turn for each degree you turn the steering wheel.
Lets say that the average street car has 900 degrees of rotation from lock-to-lock. How many degrees do you think the front wheels are turned at full lock? I'm sure it varies by car, but let's just use 45 degrees. This means that from lock-to-lock, the front wheels have a 90 degree range.
That means for every 10 degrees of rotation on the steering wheel, you get 1 degree of rotation on the wheels. Turn the steering wheel 90 degrees, the wheels move 9 degrees. Simple enough.
Now let's change to a 200 degree wheel. While the input maximums have changed, the output maximums haven't. Now, if you turn the wheel 9 degrees, you get 4.05 degrees of rotation in the wheels. Turn the wheel 90 degrees, and the wheels turn 40.5 degrees!
Switching from a 200 degree wheel to a 900 degree wheel doesn't give you a greater range of steering like people keep thinking it does. Rather, it gives you 4.5 times the precision.
Think of it this way...the reason why you see street car racers never turn the wheel more than 100 degrees in each direction isn't because that's all the steering wheel can do...its because they don't need more than 10 degrees of rotation from the front wheels.
What it all boils down to is, turning a 200 degree wheel 100 degrees will turn your car FAR sharper than turning a 900 degree wheel the same amount.

Oh, and the 200 degree wheels are actually 180 btw, if anyones counting.
Actually, my MC2 rotates just a little over 135 degrees in each direction, so its probably really a 270 degree wheel. Though I haven't checked what inputs it registers as, so maybe after 100 degrees its already putting in the maximum input despite having the input range set to the max.
