What damage do rough roads cause on a Boxster?

you'll need to keep your wheels light and small. The most rubber possible and the least amount of work the suspension will have to do. You'll want to drive very slowly over the rough bits, if there's a lot of rattling in the car you're probably going too fast. Maintain a very strict tire pressure monitoring routine (every time you fill up the gas at least). And try to keep as little junk in the car as possible.
If you commute in the same direction every day, try and map out a route that has smoothest road possible, just like a motorcycle rider would. I have the same issues as I drive in out of NYC several times a week and there's always road construction where the roads are beat to crap. A while back I simply decided that local roads are to be avoided whenever possible even if it takes me longer and I have to pay more to use the highways and toll roads. The upside is that the car can go faster and rev higher which is a lot better for the engine than sitting at idle in traffic or stop lights. Overhauling the suspension on this car cost me more than what I sold my fully modified Miata NA for.
