In the interest of full disclosure I need to confirm that place for place the GT2 does provide feedback where the T500RS does. I did a number of back to back tests on rumble strips and curbings and track edges - both wheels provide feedback in all the same spots.
I was looking for a way to describe the difference of the feedback and the only thing I can think of is to describe the way the GT2 provides feedback as you try turn into a skid to countrersteer, the "resistance" is sometimes strong and sometimes algging a little, a lot like the G25 was - sort of an on-off-on feel.
The T500RS seem sto be smoother and more progresive in this area - and almsot seems ot always offer a more realistic feel as you counter into the skid. In a real car there is real and almost constant resistance from the front wheels - the T500RS seems to mimick this very well.
Perhaps the real Pros at ISR will be able to more eloquantly describe th efeeling - I am sure they will come to the same conclusion "This a &^%##@#**%%#$!! great wheel!"
I bet the other T500ers are too busy driving to report back here.
I did check the diamond plate and the smae thing is true for this one, the plate fits really well in the F1 settign and only soso in the GT position - its not a deal breaker, just a pity. The gas pedal also has the same "stepping on gum" feel at the extremes of travel, I dont think it is causing any delay when you take you foot off the pedal but it is a littl eannoying at times. Again, not a deal breaker.
