This is still my first year driving the WCM in Autocross, so there is still a learning curve. Just used to a car that feels a little tighter than this. In reading some of the responses to this post, I think I'm in-line with what the car should be doing. It looks like our cars have a similar amount of roll in corners.
I'm still left wondering what the cure for lift-off oversteer would be? My WCM seems to get super light in the rear and really doesn't enjoy braking and turning-in at the same time. Again, this could be skill but once that rear suspension gets a little unloaded, the rear wants to come around while turning. The best way I've curbed this is doing my braking in a straight line and then feeding it minimal throttle while turning. My main question is, would any sort of spring rate adjustment help reduce this?
On the note of the spring diameter, my springs rub my axle shafts when that particular corner gets loaded up. We had to make the front mount for the rear diff and it wasn't until after we finished that I noticed how close the axles were to the shafts. Another issue that seems to factor into this is how the diff is mounted at the rear. Unless my car was missing something (which it was missing a lot), it seems like the diff has the ability to pull those rubber bushings through and make the rubbing even worse. You could even see where the bushing on the right side had pulled out compared to the left side and the difference in color of the bushing that is normally not exposed. To (slightly) curb this, we cut out some giant washers to mount on the fuel tank side to keep the rubber bushing from pulling even further through.
Sorry brain dump, a lot of words and thoughts there. Just helpful to hear other people's experience.
