you should really go get yours checked cus my friend went over a not so big pothole and had a flat,bent rim, and had to get his alignment fixed

he was going 30 or so also

If it did not ruin a tire, then your rims may be O.K., but they should be pulled and inspected. As for suspension damage, I would get it over to someone who is good and have them check it out and have them do a 4 wheel alignment on it. If not, you may wear out a set of good tires before you know it.
