Tim Tannhauser: 2004 Subaru Forester XT

Tuner Galleria: Chicago (Mar 7, 2020)

Tim Tannhauser has always been into cars growing up. "My dad had been into cars all his life," he remembers, "so I grew up working on them and learning." Tannhauser has owned and worked on three Subarus. He had a 2002 Subaru WRX with a 2.5 STI hybrid swap that was featured in a magazine, and a 2004 STI that ended up blowing up on him. "I wanted to stick with Subaru," Tannhauser mentions, "but wanted something that wasn't the normal Subaru. That's when he ended up with a 2004 Subaru Forester XT.

Since March of 2017, Tannhauser has been upgrading the Forester and making it his own and something unique. He's gained a lot of experience along the way; he appreciated different cars for what they were built for, meeting some of the best people he knows today, and creating great relationships with automotive aftermarket shops. 

Throughout out this build, and his previous builds, Tannhauser has worked with many different companies such as Touge Factory, Six Star Motorsports, P&L Motorsports, JR TUNED, Toyo Tires, SubyFlares, TIBurnt and Stroud Built, Visual Auto Werks, JDM Emergency, and Freedom Mount. Additionally, inspiration comes from his VadedMob family. "They always push me to do what I want to the car," he mentions. "I have built this car for myself to enjoy and not what other people want to see."

Tannhauser's goal is to make this Forester one you don't normally see around; to build the Forester to be a show and track car, all-in-one, and hopefully one day be able to show it off at SEMA.

"My most favorite modification to the car is probably the flares and paint job. It's a custom paint job that is a Nardo Grey base coat with a teal and white crystal pearl in it.  It's a color you rarely see and in the sun and light it can give off a whole different color."
