I haven't had any issues with ground clearance with the F.I. TDX. I have a stock height NISMO, but I do have issues scraping the front if I am not paying close attention to the dips and such. I am sure that the drop from the Swift springs will not cause any issues with regard to the exhaust, but it would make dips/speed bumps/driveways an issue with the front.
