all i ever really broke on the rat is the front kicker (but the design has now been improved so less break now & the only other real problems i have had are with the t-plate & the hinge-pin holder.. the pin holders tend to break easily & the t plate can get stretched where the hinge-pin holder is secured through it as the holes go oval shaped & eventually work through, other than that the only thing i broke is the c-hubs as the studs can weaken the plastic if tightened too much or if they take a knock at the wheel.
The only other upgrade i would suggest is to change the shocks as the tops tend to go weak & will pop off - the kit shocks are certainly very capable for club racing (i've even seen rats at some bigger race series on kit shocks), but the tops will weaken you could prolong the life a little by using PTFE tape on the threads, but the best upgrade is just to change the shocks. I have used the 75mm Aluminium Damper shocks on the front (part number 201000037) & the 95mm version of the shocks (part number 201000039) on the back but using the springs & parts that come in the kit shocks changing the weak plastic body for the metal ones.
The idle gear is a weakness, but i find keeping the diff tightened up can help as it seems to be a problem with heat, a loose diff will generate more heat in the gearbox & then with the build up of heat this softens the plastic so the teeth strip easily, also a drop of 3-in-1 oil keeps things cool, a lot of people say don't put oil or grease on the gears (just in the diff) but a quick squirt helps keep the temperature down so for that reason & that reason alone i recommend it.
Hex's used on the X2c are pretty much identical to the rat kit standard, the easy fix is a tiny drop of superglue on the pin when fitting to stop the hex sticking in the wheel & the drive pin faling out & getting lost & by only using a totty drop shouldn't be too difficult to remove the hex should you have a bearing failure or hub fall to bits.
I've only ever broken one shock tower & that was when a car landed on top of mine when landing off a jump & took the impact with the shock tower.
Spares wise, i carry a pair of wishbones & a kick-plate (just in case) the other thing i would tempted to carry is a set of c-hubs, as they can break when the stud pulls through, however fitting a longer stud & fitting a nut on the back can stop this pulling through.. if you see a split, a drop of super-glue will stop it getting weaker.
