LOL, yes the diff on the AE is soooo hard to adjust! You have to take off the tire, and pop a ball cup. That takes at least 30-40 minutes and about 25 screws.
Sport10- I have run the T4 for over a year and half and have only broken 1 suspenion arm the whole time, and that was on a 2x4" at the local indoor track. In fact the arms had so much run time on them they were starting to wear away! And they still didnt break!
