Very quite in here. Will be interesting to see the Hofer set up from the ETS this weekend gone. Large open tracks is what we run here in australia and a lot of the set up's online just don't carry over.

Getting pipped by a local in a Tamiya is a solid effort especially When Tamiya have Groskamp in the pits setting up the teams cars! They are almost unbeatable...

Key point. Lots of guys there can drive well, but if Groskamp is giving you setup advice you've got a massive advantage.

I think if you buy the diff from Spec R it suits the Mi4, the old drive shafts, when you get the diff from Schumacher it does have different out drives that fit the plastic sliders.

I have not seen the part number for the outdrives to suit the Mi4CX, check on the Schumacher site.

I got Spec-R diff off Schumacher directly and it was direct fit for my CX (didn't have oportunity to try it yet on track though).

If you want to use the SpecR oil gear diff on the MI4 or MI4LP, then you need to use the Cx rear universals. I have this fitted to my MI4LP.

The standard MI4/MI4LP universals will not fit.

Calvin.

hey Rich, I was using xray cst 650 shock oil in mine at Reedy, on a low traction track it will be loose, but high bite it is ok, and when you get used to it, steal Jeffs gear diff, put 50,000 in it, and put it in the front of your car thats for low traction, I haven't done high traction yet, but I'm thinking at 100k or more that. I should have ran that at Reedy, IT IS FREAKING AWESOME.

If you take the slider rings off, the older blades fit the newer inserts. Just make sure you're not bottoming out the blade. I ran an LP with SpecR diff and LP driveshafts with no problems a couple weeks ago.

Mike,

I tried the standard rear universals fitted with the grey blades and these did not fit, that wa with the slider removed. Perhaps I should have tried a different blade on the standard MI4LP universal. It would have saved me a few dollars.

The main thing is it is working.

Thanks for the heads up.

BTW,

I run between 700 and 1000 wt oil in my oil gear diff, depending on grip levels at the track.

Calvin.
