For some reason, my car is REALLY riding rough. It feels like it's in the front end. I checked my tire pressure and it was really low (20 PSI). I filled it up to a little over 30 and it's still vibrating. I haven't had anything done with the tires, alignment or suspension since I bought her with 1,500 miles on her. Now there's almost 20K on the odometer. This has really happened all of a sudden. It seems that it's coincidental with my installation of the steering resistor, but I don't think there's any connection. It smooths out when I'm accelerating and comes back when I back off the throttle. Chill suggested I take her over to J3 Motorsports for a precision alignment and suspension tune. At least she's looking good!
