As a side note, I have always setup ring and pinions in RC cars exactly how Kyosho now states in the ST-RR manual. Its just something you do with actual real car diffs and transmissions that most don't know. Most brands don't mention diff shims at all.

Here's a link to truggyracers-there is an excellent step by step in the build tips if the link does not work. BE SURE TO PUT SHIMS ON THE PINION GEAR, OR IN BETWEEN THE PINION BEARINGS. I purchased my truck used and had a problem after 2 races-then replaced the geard and shimmed them according to this process and now have 4 gallons and counting on the diffs.
Other than that just watch out for the fuel tank if your track has extremely large jumps or you have a few extremely rough landings. The STRR is a dream to drive.
