So I was racing and kept washing out, like I would get all squirely on the straits and caused me to do horrible, so a dude that know me saw it and said wht was wrong man, u don't norm drive like that,,, so come to find out it was my ball diff that was shot, I rebuilt it and am going to try it out at the same track this week, I took it to the loose outside track near me and it does ok, but in order to tell if it's halfway decent I have to get on the tight high grip track and try it out.....so I said all that to ask, will the gear diff be a better option on a tight high grip track, wanna kno before I bust out and get one for the sc10 cause I have one in my t4 and it seems ok but idk how it will be in the sct...

i never thought of that. I lose it on the corner more but a little on the straight i can spin this thing around very easy if i did not turn wide i had to stay on the gas or it would kick out quick. how do you know if the ball diff is going bad any thing to look for this truck is still on the same one for about two years now.

If u hold one of the tires and spin the other, it should be real smooth and have next to no binding at all!!

If you do have a ball diff and not a gear diff (like the sc10 comes with) and you have had it in for 2 years then you most certainly need to service it. Check out the thread on this site or youtube and look at several people's way of doing it and kinda take all the best things from each one. Most important is the break in process which you will here more than once, just take your time and once you have it right it WILL help on high grip tracks FOR SURE:

Yes bud, a good ball diff will absolutely help on high grip track

YEs thanks for that im gonna have a look at this weekend i completely forgot all about that been doing all the maintenance to the truck but forgot all about that. I did not know you had to break them in big bummer. Im gonna go find that ball diff thread. this will let people pass me on the straight with like butter if it bad i still came in 3 but that was some really good driving. i was also able to clear the triples just fine to.

Are you sure you have a ball diff?
Do you drive a rtr or did you build the 10.2 kit?

it a ball diff this its the older ft kit i bilt it brand new out of the box but after warching a video i think i forgot to luck it down with the two scewdrive truck

I kno that now lmaoo

Will took the diff apart no problem there that i see yet gonna rebuild it and see what happens. If you electric motor is running cool going down on a pinion will make it go a little hotter and faster right cause im only seeing 115f for temp on the motor and esc is at like 90f with the fan.

I think you mean going up (higher number) on the pinion will make it run hotter and faster. Or, go down on the spur..

ok so a smaller spur will make it go faster also so maybe i need to change that to a 72 and try it out. im on a large out door track and i get smoked on the strait. my truck is now at 75 spur and 28 p. trying to figure how two guy smoke me so easy for a stock class.

What are you using for a motor compared to the "udder guys"

31/72 would be big change... but watch your motor temps..

me and one guy are 17.5 novak according to what he said the other guy i dont know but i lost them on the straight and the only way i caught up was in the mid field. so i should keep going up on the pinion for now seem to be thr right thing

After some advise. Which are better shocks? The tf 1.32 v2 and 1.5 v2 shocks or the big bores. I made an error in ordering, that is got these shocks and ordered the 12 mm spring sets. Will the 12 mm springs work with these shocks?

Will it be better to just get the 12 mm big bore shocks?

Upgrading a sc10rs to factory spec's.......

Help greatly appreciated
