Replacing a stock flywheel, 20lbs, with a alumimun flywheel, 6.5lbs, cause any problems to the operation of the car other than higher rpm needed to move car from stop? 95GRS.
Not really. It may take your car a little while to get used to how fast the rpms drop off when you push in the clutch. But you will get better throttle response, the engine will also mover quicker through the rev range both up and down.
