Alright, no need to get all worked up hahaha.
James and I were discussing things about the diffs and he had been fiddling around with ideas and he got a ta05 diff to drop in.
The curious guy I am, decided to try it out for myself. Now, the Phi diff works great, but you just have to babysit it a bit. Some people liek to use the normal bearing for a thrust bearing trick, but I hated how the diff performed with that setup instead of a typical thrust bearing. In order for it to not slip, the diff had to be retarded tight so it never worked all that hot. The plain stock phi diff with carbide diff balls was great. That is... untill you got junk in the thrust bearing. After you clean it up it's fine. So the key thing for me was just keeping it clean.
The ta05 diff just lasts a little longer since the thrust is enclosed in the outdrive. I haven't noticed any performance differences. I haven't had any problems with it changing settings either.
Other things I've been trying since we're on the subject. So... now that we have these cool narrowed steering blocks I've been running those. I've also been dremeling out the rear arms a bit so I can use them up front.
Why you may ask?
Well, the rear arms as you know have two different positions for the rear hub. With the optional rear hub 79299 you can run the outer hole without changing the width of the car, effectively lengthening the suspension arm.
So with this idea in mind, I dremeled out the rear arms so I could fit the front steering block/c hub assembly in there on the outer hole. In order for this to work without making the front of thr car crazy wide, I had to use the new narrow steering blocks, the axle and driveshaft that is required for those, and some narrow hex adapters. But, in the end, I basically lengthened the suspension arms front and rear. This resulted in more mechanical grip for rubber tire racing
I've also been messing with the super short wheelbase (the different set of holes for the rear clamps). It seemed to work really good on my home track (Seattle Indoor Raceway). It's a very small and tight carpet track (we put carpet on top of the asphalt...). Anyway, it;s been working pretty good. It just really helps with low speed, very technical tracks if you're running a spool.
