The Wraith is a very capable rig out of the box. But, as usual, there are ways to improve it's performance to make it even better. Here are a few tips to get the most out of your Wraith with minimal cash out of pocket, and a little time/effort spent at the workbench.
Soften up the suspension:
The Wraith's suspension is a little stiff out of the box, if you plan on just bashing with it as is. If you add scale accessories, a driver figure, spare tire, use a standard 6 cell stick pack, etc. it is probably about right. I left my Wraith pretty much stock, and found myself wanting a little bit softer suspension for those high speed rocky sections of trail. First thing I did was grab two packages of our "black" super soft comp shock springs, Part# AX30223 x 2. I rebuilt all four shocks using our 30wt oil, our 3 hole shock pistons and soft springs. If you don't have 3 hole pistons, you can drill the existing holes out in the standard 2 hole pistons so they are just a tad bigger. Making this modification almost converts the Wraith to a "droop" suspension set-up, meaning there is very little "up" travel to the shocks, it's almost all "down" travel. Under the it's own weight sitting on a shelf, my shocks sit about mid-way into their overall stroke. How is that better you ask? This made my Wraith a lot more stable at speeds, as it lowered the overall center of gravity. This mod also helps it floats over rocks at full speed a lot better too, because the shocks can cycle through their travel more efficiently. As the tires come off the ground at speed the shocks extend under the weight of the axles, which will help absorb that next bump in the trail. If I had to suggest only one modification to a fellow Wraith owner, this would be the tip I give them. It makes a huge difference in how the Wraith handles at speed and over jumps.

Aluminum servo horn:
Another great mod is going to an aluminum servo horn on the steering servo, that is compatible with Futaba servos. Using an aluminum arm instead of plastic is a lot more durable, and helps your steering track a little straighter in the rough stuff at speeds. The plastic steering linkage will still flex enough in hard crashes to protect your servo. Plus, the stock Wraith servo has metal gears which most RTR's don't have.
Steel ball studs:
For performance reasons, I like to replace any plastic ball studs with steel. Ball studs are the pivot points that allow your links to cycle through their travel. The steel ball studs will smooth out the motion on your suspension and steering links. Over time dirt will work it's way into either set-up and wear parts out. But, with steel ball studs the dirt is less likely to hinder link movement. This mod works very well when done alongside the shock rebuilding tips I mentioned earlier. All you will need is 4 packages of our steel ball studs/flanged balls, Part# AXA1331 x 4. I don't have a link for these, but your local hobby shop or online retailer can get the correct parts with that number.

Taking time to make these few adjustments will make a pretty big difference in how a Wraith performs, especially at speed on rough terrain. Happy Trails!!
