I just picked up a nice-looking 20,000 mile 2006 Audi A3 2.0 TFSI, however the previous owner did not reveal that its suspension is compromised by severe rust.

While this is a pain, the situation is also a great opportunity and I am planning a complete suspension rebuild. I've read that several TT suspension components are interchangeable with the A3. Check this out:

Has anyone installed TT spindles, TT lower control arms, TT ball joints, and part of the TT rear suspension in an A3? I'm planning to order suspension parts soon and would like to install as many TT parts as possible. I'd love to combat future rust with quality aluminum suspension parts and would enjoy the weight savings/ increased performance and adjustability of the TT suspension.

I normally drive a 1993 300zx and I can't find as many aftermarket suspension parts for the A3. If the TT parts can work, please let me know.
