Just finished building my Tech Racing M03M conversion.
Easy enough to build. I think for the price it would be better value if Tech included a set of their shocks, or some universals.
I worked out the cost and nearly died!
Lucky I had some of the parts already
You could save $$$ by using dogbones instead of universals, and plastic shocks instead of TRF units.
