So put me down as a fan of the GTEYE. Took me a bit to get there.
Originally installed the GTEYE as the brake, moved the brake to the clutch, and the clutch to gas. Closed it back up.
Then it looked like the gas was shorter than it had been (which I attributed to the shock spring being shorter). So I opened it back up and put the gas spring back in. After I did that, I eyeballed it and realized it was making no difference. So I pulled the gas spring back out and again replaced it with the clutch spring. Then I closed it all back up.
Did one lap and realized I absolutely hated the clutch spring with a passion. Gas pedals have very little resistance in real life and the tension on this thing was all I could focus on. It wasn't natural and was killing my sense of immersion.
So I opened everything back up for a third time and replaced the clutch spring with the gas spring.
With everything finally settled, my initial reaction was I wasn't noticing a whole lot. Subtle at best. But I wasn't braking enough and was missing corners a lot.
So I figured the best thing to do was load 67 Monaco in rF2. That's short track with lots of demanding brake points. After about 5 - 10 laps, it began showing itself. My braking is much smoother and natural with this thing. I can see where some people would frown over spending 30 dollars on a simple spring, but I think I'm going to get my money's worth from this
