I replaced the springs and dampers on my 2010 S3 8P with Bilstein coilovers. The original suspension was on the car for about 2 years and has covered 15,000 miles. I sold the car recently with the Bilsetein suspension on so I no longer need the genuine Audi parts. I intend to leave the advert open for 30 days. If I have not sold the suspension I will bung it on eBay.
