Is there any aftermarket suspension available for the A3 Sport (17" wheels, 06 plate) that will produce a more comfortable ride? I have had the car 1 year now and honestly at the point of selling it as it niggles my back. Already changed drivers seat to Recaro Ergomed which has helped. My old Mk4 GTI TDI golf with 18's was more comfortable (very soft/rolly suspension set-up mind you).
