This is my most recent vehicle purchase, and due to the weather conditions I have yet to take it out to a track. However, I must say that this model is, while not the highest performer I own, it is possibly the funnest vehicle I have driven. When I head out for a drive, this has been the one I pick up first lately. I can make a few immediate recommendations for tuning, but finer details will have to wait until I'm able to experiment at a track.

     The very first thing I recommend doing before even driving this model is to switch the rear hub carriers around. If you have the plastic carriers, this is not necessary as the right and left are identical. If you have the aluminium hub carriers as seen above, then these are designed to give an extra 1.5º of toe-in. The lower control arms already have a set 2.5º toe-in, so this makes a total of 4º. I strongly advise swapping the rear hub carriers from the left side to the right and vice versa, as mounting them backwards will negate the 1.5º they are built with, leaving just 1º toe-in on the rear.      The aggressive 4º toe-in from the factory makes the car more "stable," i.e. more resistant to spin-outs, but the full 4º will cause understeer issues under throttle in which your model will not be able to turn properly. Furthermore, the aggressive factory-set 4º will also lead to rapid tire wear. Reversing the hub carriers and setting toe-in to 1º may require slightly more skill on low traction surfaces, particularly when exiting corners, but with some practice you should find that you will actually have more control over the vehicle.

     I can also tell you immediately that the stock springs on this thing are quite weak. Out of the box, I recommend dialing in some more ride height in a feable attempt to lessen the amount of times you will bottom-out your suspension. The front springs are especially weak, and would be the first ones I would recommend replacing. I have heard that Team Losi makes a spring set that will, perhaps unintentionally, fit on these new, large-bore Traxxas GTR dampers. I have not had the money to invest in a spring set yet, but I will definitely update when I do!

     One more pro tip: If you find your suspension looking like the above image, then you may need some minor adjustments...
