There is a lot of discussion in the forums re: bump oversteer on these cars and the differences between the '20 and '21 models in regards to suspension. There are also a few really solid YouTube videos discussing this phenomenon, how certain people have tried to address it, and some speculation re: potential design issues and non-design-related causes, noting that the issue got worse when cars were lowered. There's also a good thread on the forums in which some folks are experiencing the front of their car pulling to one side from a stop under power, and at least one user who experienced it to a greater degree after lowering their vehicle. In addition, there are a few examples of lowered vehicles having an issue with sway bars rubbing on tie rods enough to cause them to snap. At this point, all of this information leads me to believe that lowering one of these cars simply through the act of replacing springs is not advisable at this time. The benefits don't seem to outweigh the reported problems and unknowns until this can all be hashed out. Can anyone tracking their cars comment on the benefits vs. any of these issues? I have a set of aFe sway bars and Eibach springs on the way and I'm thinking about holding off on the springs until some of these issues are hashed out. I personally think a post-lowering or post-delivery alignment to ensure the car is within factory specs or setup for the track will do a lot to help most of these issues, but only time will tell as more data comes in. I'm not sure I want to risk it until them. Note I'm having none of these issues on my '21.
