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.
