Yeah i supose that is a waste of money if i use the 300,000 lol! ok so 7k in the front and 5k in the rear then :) How come thicker in the front and thiner in the rear? I have a locker in my parts bin and robinson racing pinion and ring gear so if i want a locker i'll use that.

Most people use 7k front 5k rear for the first time, infact it's recommanded in the manual. Why I don't know but it work's.

With a brushless motor and thin oil it's hard to notice a difference, there is so much torque that thin oil ain't gonna do much. Unless you really want to hill climb i'd put 10k front and rear, but I have no idea how this would affect the truck's handeling. One thing to keep in mind, the heavier the oil, the larger your turning circle would be.

I can say that the size tire you run makes a difference to. The bigger tire has more leverage over the diff oil. I like the 5 k with small tire but wish I had more for the bigger tires.

oh ok i run both 40 series and normal size wheels, i'll try 7k front and rear and see how that goes.

I run the 6 spyder kit. If what serum say is true about the 8 spyder gear set. Which makes sense in every way. The 7k should be good really. Have to let me know on this. that away I know what I need to change over to.

what shock oil wt shock i put in my msr5 shocks? i have some 45wt will that be good?

are you running all 8?

yeah all 8.

I run 50 weight with 8 shocks. works out good for me. I have ue shocks though.

is there a big difference between 45 and 50wt?

I don't think it is a great deal of difference. I run 18 cells on mine as well. I think the 45 should be good as long as the holes in your shock pistons are not to big.

i you race you would probable be able to tell the difference. but otherwise i dont think so. also, i would try the 45. the bigger ue shocks require heavier oil.

cool thanks guys. There are two holes in the pistons about 1mm diametre each

I just filled two shocks and they seem a bit springy. I found some kyosho #800 shock oil so i might use that aswell. I think i'll leave the two i have done and use one on each side at the front and i'll do another two shocks with the 45wt oil but put the one hole piston in and use them for the back, then i'll do the remaining 4 shocks with the kyosho oil but put the 3 hole pistons in cause that oil is quite thick. i'll see how that goes lol.

what kind of springs are you using? firm? soft?
