I can't imagine it being much better but would love to hear from those who have tried both.
Well the fluid diff can be like the spool or loose diff action,and it never slip and ball diff does slip...

So what should I expect to feel/see from my 3 Racing diff over my loose kit diff? I imagine it will pull out of corners much better but does corner entry etc feel better?

Also, I assume it's obvious which way around it goes in, but if it's not?

Cheers!

Just as you said, with the fluid diff you'll notice more drive out, and you'll be able to drive more aggressive going in.

The thicker the fluid, the more drive coming out, but that also creates understeer going in. The key is to tune for the track conditions. I'd try something thick to start, and as you get used to the feel of the car afterwards, you can then use thinner oils to get back that steering on entry. Are you racing carpet or asphalt?

Hey jesses
Most of the mini guy like the spool on carpet . I didn't think the spool was a good option..But atfer watching Kody running the mini,it works better than ball diff....I lkie the ball diff better for asphalt..
but again I don't run after market parts on my mini

I'd be more apt to run a shimmed stock gear diff with some "secret-sauce" inside. Got one ready for H30.

I think if I ran a spool up front I'd probably shear something off the first time a TC plows into me. ....No give.

Now you're talking! My shimmed gear diff is a great piece of work, but no secret sauce involved. Just a few extra shims, a dab of AW grease and its good to go. Ever tried running a one way? Great launch, incredible turn in and NO BRAKES! Two out of three ain't bad.

Fx, I usually add one shim more, per side, where the manual shows. So instead of one shim per side, you'll have two. They go between the diff case (gear) and the pinion gear (the splined gear where the outdrive slides into).

Wutup Danny, yeah maybe in 2014 being that it's 20th year anniversary of TCS makes it pretty tempting...not tempting having to take off all aftermarket parts which I'm used to running with and bolting on the T parts, but should be doable.

I see, so the main feature is no slip, thanks.

I've been using 2 extra shims per side, with the outer ones glued to the diff case. This transfers the wear to the metal parts, even though there's not much wear. The cool thing about the is you can use the diff case screws to adjust the stiffness. Just make sure they're even, or you'll see weird premature wear. Also, I drilled a tiny hole in the side of my chassis to allow access to the case screws, doe occasional adjustment.
