You might want to get the CNC'd center braces as well as the Z-brace (it will stop chassis warping from motor torque) you can usually find them on ebay WAY cheaper than hobbie shops want for them (most places want $50 a piece I got the braces and Z-brace for $30 total off ebay

)
And also get a metal geared steering servo I use a Hitec 645MG which cost me under $30 and its working good so far

. The stock steering servos pretty crappy IMO I found it not to have smooth movement and was lacking in the torque department.
+1 on what he said. however the Z-brace isnt a must IMO, i have ran it both ways, Z-barce is better but not a must, but the chassis braces are a MUST!!! if you dont you are 95% more likely to bend the chassis, seen it quite a few times.
