I agree that it is hard on the suspension to go fast around a corner. And it does wear down the tires faster. BUT it is a lot of fun seeing just how fast you dare go around a posted 35 mph curve. My wife managed to hold onto a 35 mph curve going 55. (yes, the limit was 55) While it may have worn the tires a bit, compressed the bushings more than ever, and likely burned more fuel, it was exhilerating, fun and LEGAL.
Adding a front spoiler would help a bit i think. But the effect it would have on the mpg would likely be disasterous
