IF you have followed AE from its Inception, you know that for them to completely change and make a new car is few and far between. They JUST released the B44.1 less than a year ago as well as the B4.1 WE. Its not cheap to re-tool and re-engineer a car from scratch. AE does several small changes over the course of a couple years, but realistically, we see a NEW car, what 4-8 yrs? When Lipo was the latest, they tweaked the Shock tower. Later they lengthened the chassis. other than the changes with the BB setup, nothing has really changed.
Knowing some people on the Inside at AE, I can tell you you won't see a "NEW" car for quite a while. What you WILL see are FT upgrades, or WE upgrades. much like the recent FT SC104x4 upgrade, it wasn't a whole new truck, it was a few key elements and upgrades of certain parts.
My guess is there will be a BB suspension upgrade with some different shocks, perhaps towers and arms for geometry, but other than that, they might start changing the WE to include a BB shock, but overall, its silly to keep asking when is the BB kit is coming.
AE has HOURS and HOURS in testing and tuning to get something right before they just throw it into production for the masses. I've spoken to Cav and other people at AE and when they aren't racing big events, they are testing products and working on prototype parts for later release. If something isn't going to work for Cav, Mayfield, And the other top AE drivers at the PRO level, why would they offer it to the rest of us Amateurs if its not 100%? Chances are the stuff you see in the pics wont look the same when it hits production anyway. Name a 1:1 concept car that looks EXACTLY like a later production version? Exactly!!
For now, mix and match components and test different ideas and see how they work for you on your home tracks. I understand the cost factor in trying new things, but at least you are satisfying your desire for the BB setup until an "Official AE" version is released.
Sorry if this comes off like a rant, but maybe because I've been involved in this hobby for over 15yrs and I've seen the changes take place and the time frame in which things move. It bugs me when people are screaming for NEW NEW NEW when the current stuff still kicks ass and wins Championships. When its perfected, you'll hear about its availability. NUFF SAID!!!!
