So, CV3 pedals.
Wow, just wow...
So build quality, absolutely fantastic, design is brilliant, feel of both pedals are great on my feet (socks).
I was using t500 pedals before, and the extra sensitivity of these give me so much more control, I can do things with the car now that if I had tried before would have caused me to lock up or to spin out.
The vibration on the brake and acc pedal is strong enough for you to feel, the brake is especially useful for letting you know when you're about to lock up. The acc pedal gives you a feeling of understeer when it occurs.
Look at it this way, I just took .9 of a sec of my best lap at Spa in the skippy after 2 laps, maybe it was partly the weather, but I could nail my braking every time with no lock up, so much more confidence now.
If you have standalone pedals already, then maybe these wouldn't be worth it, but if you have G27 or T500 pedals, then yes these are a huge upgrade..
You also need the latest version of Fanaleds to have the vibration working in the pedals..
