Made the change to B44 rear arms and 0* hubs this weekend. Probably the best the car has ever felt. Tons of steering and the rear is still very stable.
I'm thinking about doing the U-brace mod as well, but, what exactly did that help out with again? I can't remember...if I can recall its something about bumpy track conditions and helping with stability?

You only want to lower the u brace if you run the "c" hub towers. Personally, I don't think its good unless the track is relatively smooth, my home tracks are fairly bumpy and these make the car harder to drive. They give the car more steering without really sacrificing anything except maybe a little stability. Usually these are very good on wet indoor tracks.

From what I remember reading (I could be wrong) when running the b44 hubs you dont want to run the u brace mod. Thats only if your running the FT hubs with the c/f C plate. The b44 hubs is equivalent to the A plates and you should actually put a washer under the inner ballstud.

For what it's worth, my car feels broken if I'm not running C Hubs / Shaved U.
Doesn't flow smoothly through the turns.
So after 2 full race weekends back on AE springs, I am going to flip back to Losi this week and see if I feel a difference. After 2 weeks on a rough track, I feel the AE springs are just as fast (in my case faster hotlap) but they are not as consistant and maybe more darty.
I'm going to test the theory and see if my overall lap times come down with the Losi springs. This is in the main so it's race condition, not just practice.
Again, I am really leaning towards the "they look cooler" reason as why to run BB springs.

3.0 will make your car want to "straighten out" when you hit the throttle so it can cause more of an on power push. I switched to 2.5 with 0 out board. Try it. Also make sure you have 2 deg anti squat.
