You just have to find it on ebay or something or you can try energy suspension polyurethane bushing grease($18) for more diff action than the ofna diff lock lube but still stiff enough to stop diffing out... Bert Knowledge is power !!! LOL !!!

I've locked up diffs with blue-tack before which just Involved shoving as much in that fitted, but the rules at the track I'm going to run at say:

- using the Tamiya kit diffential components only
- Oil type sealed diffs are NOT permitted
- Ball differentials are NOT permitted
- you MUST retain functional diff action at all times

which lead me to remember the blue-tack method from the M03 days except I don't remember lhow it went to get about 80-90% stiffer.
