it looks like the same radius but mine is a bit of a fuller circle if you get my meaning lol
its closer to a half moon than yours is.
i find it makes my pedal sit slightly high but the biting point is nice , i'm guessing as urs is the pedal must sit pretty much in line with the brake and accelerator??
compared to the three plastic ones i've tryed...... and broke the feel is very positive and now i'm not worried about breaking anything
