Anybody knows if the drivecups of this gear diff interchageable between different models? ie: I have a spec r Yokomo one but would like to use the xray spec r drive cup or a spec r tamiya cup.

Why 300cst? With 150 it is already hard I believe with 300 it is going to be like a spool isn't it?

I use 500k in my front geardiff with great results, and so are many at my local track (with a lot of tight 180's).

No, there is a lot of leverage when you spin the diff from the wheels and not the outdrive, so even 500k is fairly free compared to a spool.

Fabricio

As I do not have 300k neither 500k I will try with 150K, on the rear I am going to use 2k.

We do not have so many 180, I think 2 the others are medium to fast corners, I am going to run the 17.5T sensorless class, so not so fast I think.

I will buy 300k and 500k to try out and have the feeling of it, in the rear what you guys are using? 2k is fine?Some guys on my track said 10k but I think is too much, nobody here got to much experience to say as most of the guys are racing nitro, we have the EP class but the GP class is much bigger.

Nilks

The TOP Racing guys at my track are using 10k in the rear with the TOP geardiff. But I would recommend using around 1k-2k with the Spec-R geardiff. I am currently using 2k, and the car is easy to drive with ok steering. I will try to use 1k in the near future, to see if I can get more steering.

But you can't go wrong with 1-2k. The Tamiya guys at my track uses 1k, so start with that.

And the car doesn't unload?

iTrader: (13)

have not had a issue with them unloading yet. there are a few guys running it this way at the local track. ive tried 1000, 5000, and a few others and not of them felt as consistant or as smooth as running it with just the 10w-40

Happy to say I now have 6 race days and 4 practice sessions on the Spec-R gear diff and it just keeps getting smoother! If I had been running a ball diff for the same amount of time I would have had to redo it three times. The track I run at is med to low bite carpet so 3k seems to work best.
