The mission has great corner speed and acelleration.Especially with the one-way. Yea I would say a shorter wheel base and 3 degrees toe in. that would help a million. If that dosnt help try a tad bit softer spring or softer compound tires in the rear.Another thing is that when its hot outside (you probley already know this) the car wants to get sqirley for this problem during the day I run a harder compound tire, I run Sorex 36r during the day and cs-27 during the night. Ive been through this many times and it sucks when the back of your car is all over the track.
