ok thanks, my old diffs were completely untightened, cause i run 80% asphalt and pavement... i will see what will be the behaviour of my car...
and yes if it's some silicon oil it can not be affected by temp... that's right Serum, I forgot that fact...
again i will let you know how it runs... i build a new E-maxx actually, from my old one that i shew here 2 weeks ago...
