I'm planning a build for my '04 t4r and I'd like to have suspension that I can adjust the height of from inside the cabin. I'm pretty new to researching parts for a t4r, but from the bit that I've done, it appears that getting Bilstein 5100's, airbags and an air compressor would do the trick. Has anyone put a build like this together? I'd be interested to hear how it worked out, what they liked and didn't like about it.
