Default hyper 8.5 spyder diff

Just want to know about front/rear diffs on the hyper8.5's, ive almost finished my conversion except for this.
Will it make much difference changing it over to the spiders diffs?

There is nothing wrong with using spider gear diffs and they do not use grease and oil , just regular diff oils .


Nover367 , sounds like you are thinking of Torsen diffs .

I don't think it's a neccesary to change, when I had my H8.5 I preferred to use a standard center differential from a H8 than the spider.

Why do you say that? Ive got the spider centre diff and using the standart front/rears I didnt have much run time on the standard centre diff and just wondering what differences you found

If I was you and lived in Europe i would look for an xray xb8 ec. They are great for the european style tracks and are pretty much bullet proof for bashing! All the best.

I liked the spider center once I got it thru my head that it required silicone 1,000 to 2,000 less than the normal diff becasue the 2 extra gears created a slight extra drag. Did not try a spider in the front or rear. When its right its very smooth, no slop and strong as a diff can be.

well simply because it tunes different than the standard, it's just a matter of preference.

whenever possible I like to use the spider diff up front. The reason being because of the 2 extra gears the silicone tends to spool up more. For example if I put 5k oil... off power i get 5k but when on power while accelerating it acts like I have 7k. So more steering all throughout the turn
