Braking, braking, braking...combined with the ability to have a tuning option more to setup your car with a diff.

The more specialized the 1:10 class and its drivers got over the past years the more it's the diff that was used. At least this is the trend in Europe.

i have always liked the one way, when I went from diff to one way I was quicker around turns, I haven't been back to diff yet.

Im curious what you guys think about the solid front axle (spool) I know it was a popular modification done in the past with cars such as the impulse.

How popular is it now adays with more modern cars?

I run a spool in all of my touring cars.. Drive it in hard, and full throttle on the way out.

The diff does have some advantages though, its not nearly as hard on the drive line, and you dont break parts if you tap a board. You can also run the front diff with a really thick diff fluid. It will almost lock it up, but still has the give in the driveline if you should hit something.

Not sure if this is factor.. but a spool is considerably lighter than a front diff at least in current RRR (waiting for the RRRR

was a hardcore one-way addict really for me, but after trying and adapting to the diff it felt nice too. having said that it really depend on your preferences and driving style , track layout too.

but in my case the difference ( lap time) was not drastic. presumably differ results between drivers.

-really like the one way when diving in or exiting corners
-the diff/spool for braking requirement.

tq.

The spool is fast however under hard breaking the car is eratic and not consistent what a lot of factory drivers including myself we have been running the diff with like 300,000-500,000 diff fluid so it acts like a spool exiting the turn but acts like a diff entering so you can drive the car harder into the turn and let it rotate. thats my experiance with the xray.

That's my opinion. With the diff you have much more tuning options. With either a one-way or spool it's all or nothing.

I agree with others on the Diff. The fastest guys at my home track use front Diffs. I'd use a one way diff in general for a large track with sweeping turns. Then again some just use diffs for any track.

I have recently fitted a solid front axle on my impulse, the only problem is i have a hard time keeping the stub axle grub screws from coming loose, even with blue loctite. It seems with the way it's designed it will always be a struggle. I really like the way the car reacts to steering inputs at speed with it fitted.

but after hearing what you guys think of the stock open differential with silicone fluid i may try it.

what would be a good viscosity to try out first? i have access to many different ones at my work anywhere from 5000 to 1,000,000 centistokes

most people run 100,000wt plus, i've just got 300,000 to try! just been trying out the new oneway on my car, that feels really good though the turns, home track is fast flowing though and only really need the brakes on one corner
