A rhino with performance knees
I decided to replace the factory springs only, instead of changing the whole suspension with a coil over system. I believe in the DRC System developed by Audi for this beast. Once you replace only the springs (they have to empty the shock absorbers hydraulic fluid first), then they refill the shock absorber to the new level required for the new springs specs and height. I've been more than satisfied with them and also the Hartmann wheels 19". It's been the best choice I've done for the suspension.
