Maybe they are waiting for the release of the T5? I cant see them releasing a new buggy, and not a new truck. Maybe there isnt enough interest (currently) in ST racing to justify a 'retool' for a 'new' rear tower.

I just happened to see it on Cav's CRCRC setup and figured i would try it out. I had a spare rear tower and used it as a jig. MAN does it make a difference though. It feels like a B4... just more grip, stability, and weight transition is a little slower.
