I can tell you guys from first hand experience that I ran the KF2 SE in MM setup with the KIT SETUP on there and was able to be competitive on a medium grip clay surface. I switched from a B5M FL and it didn't have the insane forward bite that the AE car had, BUT I had WAY more corner speed.
Once you guys figure out that running on clay is 99% tires, the rest doesn't matter. In fact we had a guy come out with a Traxxas Bandit (I think that's the buggy) and he won the 17.5 class. His tires were perfect and because of that, he destroyed the field with a 'TOY' car that was severely out dated and out classed tech wise.
Anyway it's nothing that you guys haven't heard before, and bottom line is that this car may not be the right choice for you. Just wanted to make sure that you understand that racing 2wd buggy is 90% tires, and racing clay 2wd buggy is 99%!
