I'm lowered on Swifts. After about 7k miles I have yet to bottom out. I scrape the little flimsy chin spoiler once in a while though.
You'll be fine unless your area has a lot of asphalt roads with buckling in the middle of the lane. I've learned where these few spots are in my area and avoid them at all costs.
If you don't know what I'm talking about, its where the asphalt is raised up 3-5 inches only in the center of the lane (think tectonic uplift) so your back wheels are unable to lift the exhaust, rear braces and stuff up over the bump. They're actually pretty scary and dangerous. I've tried to get my city's street repair dept. to take care of these things without success
