New 20" rims now clutch feels different.

3 Things change when you play with your wheels.
1. Mass change: You'll need more energy(power) to spin up and more heat will be generates to slow down your wheels.
2. Diameter+Mass change: Gyro effect will make it will feel a little more difficult to turn your wheels and car at speed.
3. Diameter change: Gear ratio is made longer with a larger wheel. And your speedometer is registering a slower speed then your actual.

Your noticing #3 most of all which is why you think there is an issue. Changing the clutch will not effect anything since your clutch is not slipping in the first place any more then it would have before. What is happening your asking your engine to do more then it had to do to accelerate before but your HP remains the same so it feel different (and is slower).
