These things are pretty fast with just a 13.5 and they act like they are just too light to stick to the ground.
I'm considering even more weight or going really light on the suspension stuff.
Ultra light oil and springs, go so far as to make it bicycle in the turns then bring it back to more firm from there.
Trying to figure out how to beat down the AKA foams like an 8th scale would do after a set or two of tires, that is supposed to be the hot ticket or maybe a new set of 8th foams that start out a little softer but stiffer than the stockers.
