I'm pondering updating my B44.2 with the Schelle kit since I prefer the slipper/ball diffs on this car but I hesitate to invest much more into this kit with presumably more new cars coming out this season.

I see that a couple makes of "super shorty" packs (2s pack in 1/2 of a saddle config.) out there now. Doing a little quick math shows me that I'd come in 10g under legal weight if I used one of these in my current setup.

Edit: closer examination of my Avid chassis reveals that the motor mount can't easily be moved. Any change in that regard will require significant changes. If the "super-shorty" is to be employed, it'll simply be removing 1/2 of the battery.

This option is appealing because I run a 13.5 spec class.
