Please note this is thinking out loud!!! This is more just trying to start the ball rolling on ideas on the problems with the 22, maybe we're looking at it wrong!!
Just thinking from the ground up. If antisquat is designed to stop the back end drooping under power, then due to there being a lot less weight over the rear end maybe we are all running far too much antisquat, and not letting the rear wheels get the weight shift they need.
I was thinking that everyone had the X-6 in mind when thinking of the handling they expected from the mid motored 22, but the X-6 places the battery so far rearwards that you actually have simular weight distribution to a rear motored car. The 22 has the weight further forward, and so maybe base line settings brought over from the rear motor are very backwards.
The X-6 is known for being able to put its power down without the back end steppig sideways as much, in theory this could be because it has the same rear mass, just less rear inertia as there is no massive motor hanging behind the rear wheels.
I'm thinking the 22 in theory should have harder fronts (due to more weight) softer rear (due to less weight) less antisquat (due to less inertia over the rear wheels), which is where running 50g right at the back turns this cars antisquat into a setting closer to correct, rather then changing the antisquat to suit the car, and less camber on the rear wheels as the lack of weight doesn't roll the car as much. This list is ever growing, so if you think of anything relevant then pipe up!! Also maybe I need to look into the touring car guys as they use cars low inertia (putting weight nearer the centre) to help with certain handling qualities, maybe the next thing on the to research list.
I don't think this car will ever compete with the rear motors for out and out drive, unless there is so much grip the rear motors are lifting the front tyres.
I personally think people need to know that mid motor is sacrifising rear end grip for what when setup correctly gains cornering speed and stability, also the changes in direction can be done with much more control. However the base line settings are just pure wrong.
This cars mid motor setup is a completely unique buggy weight distribution and inertia level, I think I'm on the right lines with the rear end camber and shocks, I think I need to rethink a few things from the ground up, but stealing things that work for other cars is unfortunatly not going to help with this car.
Just food for thought guys, hope I'm not rocking any boats.
Any specific questions please feel free to PM me.
