Here is a bagged mk4 GTI that was just done last week with a list of components and materials that were used.
A lot of ptc fittings used for easy of installation.
Then 1/4" line was used through out set-up except from compressors to tank were 3/8" line was used.
Full Airride Technologies E3 management system
Dual Viair 400c compressors
2 water traps
Masontech Strut bags for the front
Slam Specialties re-5's for the rear
Bilstien rear shocks
a false floor was created using 2x6 boards. The tank was then painted using yellow one shot with the Dorbritz Design logo
all wires are tucked away cleanly as well as the airlines.
The false floor was then cut to fit over the tank and covered in carpet to match the factory set-up.
The over all simplicity and cleanliness of the car is what makes it great looking, understated but functional.
Thanks Nick for the project!
