So after having BE Breyton 20"s that weigh close to stock for 2 years and more curb marks than I would like on them, I opted today to switch to the 20" TSW Nurburings and General G-max tires. The salesman says Continental actually makes General, and I had read some positive reviews on them so I figured I would opt for them. Between the tires and wheels the rotating mass should be cut by close to 15lbs a corner, in my last car (G8 GXP) that was dramatic in stopping, going, and even steering the wheel. Does anyone think this como will be a good performance gain on a SHO PP?
