have saw that there is a DCJ kit from Spec-R for XB4.
have anyone tried it out? i need some feedback before i plunge into getting it.

from what i understand from touring car drivers, DCJ smoothens out the steering in TC. I've tried it on my TC, and it does helps alot. however, i'm not so sure if it is a necessity for off road.

gearing
I need a good starting point on gearing.
I'm running in a "stock" 13.5 class. No timing or boost in the ESC.
I'm being told to shoot for a final drive ratio of around 7. But I can't fit anything bigger than a 26t pinion. And to get near the 7, I need a 28 or 29 with the 81t spur.
I've tried 26 and 25 pinions and to make any speed I need to add ~20 degrees of motor timing. Plus, I can't make a long double jump that others can.
Help, thoughts?

Awesome option to play with if you need some rear traction 
Replaces the plastic shim under the rear diff.

LOL Been there myself. Sucks for the wallet, but I LOVE the ingenuity!!!
Pics PLEASE!
All these sugared tracks… is it really necessary? Is it really "Off-Road" racing if you're driving around stuck as if F1 slicks on asphalt? I think the Red clay is sticky enough but dirt enough to be the standard surface which every sanctioned event should use. If you want that kind of grip, run on-road.
