The H&R Ultra Low coilover kit for Audi A4 Quattro and S4 B8 (2009–2016) is a tuner-focused solution for extreme lowering intended primarily for show vehicles. These coilovers offer very low ride heights and require an experienced installer familiar with the modifications involved—smaller tires and wheels, fender trimming or liner removal, and attention to negative camber may be necessary. Consult your installer before purchasing.
