Just bought a 2004 Passat GLS 1.8t Variant. However it's time to start making some small modifications, and I would appreciate some suggestions. First, I want to put 17s on it and drop 1.5", does anyone have a pic of a variant dropped 1.5" with 17s? Does this affect the warranty? Second, I want to chip the engine. If I get the chip switch on the GIAC can I get it past my dealer? I'm not going to be racing or going to the track, just running around town. Will all the components of the Passat hold up to the added boost and torque, or do I really need to change the exhaust and DV? Thanks in advance!
