I look at the features of the MSX conversion and even though it is pretty expensive by the cost estimates, it is worth the time and aggrivation saved in changing diffs, spools, one-ways, gritty diffs and belt tensioning with those bolt together bulkheads!

On the Tamiya USA website it states it is for the 415MS and 415 with LWS kit. I have just a regular 415 and no LWS. I don't want to get involved with the LWS kit. I don't see the reason for the MSX to require the LWS as it is just bulkheads, shock towers and top deck. Any one care to comment on that?
