Hi, I had purchased a new Sportwagen in 2012. Went to the Audi dealer and purchased the springs/shocks for a similar year Audi A3 TDI Sportback w/ sport suspension. I figured that it was the closest match to the VW. I also installed the Audi TT upper strut mounts. I purchased (but have yet to install) the A3 sport suspension/S3 front control arm bracket (rear mount).
My goal was to make the car handle better w/o dropping the ride height. While there’s a bunch of excellent high quality choices, most lower the car. I didn’t want threaded struts for the street. The factory engineers do a great job getting a balanced spring rate that works well in most situations and the correct shock valving. In this case the ride is firmer, you do feel the imperfections in the road, but it doesn’t beat you up and it's fun. It’s going to be similar to a GTI. I’ll do 650 miles a day and it’s not problem. I put 100k on this set-up and never had a single regret. A year ago, bought a 2014, and this was the first upgrade I did (I’ll put the control arm bushings on this car). This setup should work on 2009 – 2014 Sportwagens, do not know about other years.
With 15K miles (so the springs have settled), the measurements from the wheel centers to the edge of the fender – front - 14” & rear – 13 ¾”. VW has spacers that can be installed with the spring for height adjustment. Some of the related bolts are “stretch bolts”, don’t reuse those. And if you have very many miles on the car, it would be worth checking for worn components (ball joints, bushings, links, CV joints, etc). Lots of DIY’s online, job is not that difficult to do. Shop around for the parts, can be a big difference in markups. One dealer was going to charge me additional shipping because the gas shocks are “hazardous materials” so be aware of shipping costs when shopping.
These are Audi part numbers.
Ft springs – 1K0-411-105-DB R springs – 8P0-511-115-R
Ft Struts – 1T0-413-031-DB R shocks – 1K0-513-029-HQ
Rear mount for front control arm L – 1K0-199-231-K R – 1K0-199-232-K
The Audi TT upper strut mount is easy to find online.
