Recently, I bumped a high curb at 2mph (safeway parking lot at night. No, I wasn't drinking) and caused $3,600 in damage. I regularly will scrape on parking lot stops (blocks), coming out of my driveway and numerous other situations. Forget about the aerodynamics of the car at 155mph, I just want something that looks good, but is a bit higher, or made of a more flexible material so that I don't live in fear of higher insurance premiums (they stick with you for 3 years). Thoughts?
