Ok, I have a couple handling question about my buggies, both SW Mayhems, 1 is a new RTR, the other in a fairly used Pro. The pro handles much much better than the RTR. When I turn the RTR wants to just flip while the pro seems to very hard to flip. The RTR also seems to get the back end loose much easier when coming out of a corner, wanted to spin the buggy making it hard to control I am running the stock tires on the RTR and prolines on the Pro, but they seem to be very similar tires. Here is where the differences seem to be and I was wondering if someone could explain them a bit to me. The one I can understand is the springs. They both have the black springs, but the pros have a lot less tension on them I am guessing because of the use. This buggy is #299 so it has been around the block. I have changed the RTR spring to the softer red version and will test this today. The other difference is that the RTR has more toe in on the rear end than the pro does. The problem with this is I dont really quite understand what this does.

Setups on both:
diff silicone 5f, 7c, 2r
SW .26 with roto start
RTR stock pipe, JP-1 Pro
30 wt shock oil
-1 camber front and rear
slight toe out on front, both buggies set the same
center cvd's
