The last race I had my head screwed on right and did very well with the car again. It was the same easy to drive missile for all three races. The following race it started to develop a double steer. Then it started to throw the rear into the corners. I rebuilt everything. I cleaned everything. I realigned...you get the idea.
Well that chain of events sent me off on a tuning spree. I played with just about everything I could over the last couple weeks of track time. First off i would like to say that the car could be a step or two off on chassis setup before it really effected the clock. Very easy to get in the ball park. One thing that threw me for a loop is the side springs. I get the concept, soft means more mid corner rear traction. But when lowering the side spring rate to softer I had to dope less of the front too. Still trying to wrap my head around that one. Any way...
Partime, I have that problem as well. 3 weeks ago I raced and the car was on rails then the following week it started developing this double steer and the following week it was just loose. I hadn't made any changes and tweak of the car measures good, there is something else going on that causes this and I don't know how to find it other than take the entire car apart. I had this problem before and disassembling the rear pod completely and putting it back together fixed it even without changing a single part.
