Reflex Racing drivetrain upgrade
 

Trying to give this forum a little boost because I find this kit to be very interesting. I hope others will start contributing.

Reflex Racing has a "shimmed diff" kit on their site. They say it makes a huge improvement in performance. Wanted to point it out since there aren't a lot of mods out there yet.

How to install it

i have heard that you do not need this kit; if your cars diffs seem like they bind, its been said that they need a really hard break in.
I know my cars diffs were not great at first but after driving it really hard with the lipos it seems fine now.
Some may be differn't though
