Awesome

Have you decided now on whether you are going to upgrade the rear with the M3 rear sway bar or forgoing that now?

* Car is now finally neutral. No longer plows in understeer. On a long 270 corners, I can balance the car with just the throttle. The front never steps out as it has a lot of grip. The rear will step out first but only at the very end of the grip, and it is gradual instead of "snap oversteer".

* The car is predictable. I can throw it in the corner and now I can predict exactly what will happen and (more importantly) when it will happen. Previously, it was very unpredictable and inconsistent.

* The tire wear is much better controlled. This was expected as there is a lot less rolling.

Overall, this has been perhaps the most significant change I've done to the suspension in a very very long time. Now I have to relearn where is the limit again and drive with confidence at it.

Too early to say to be honest. I need to raise the car a little bit because the TCKLine 400lb springs are too short. With the front coils raised at the maximum safe level I am rubbing the front tires. I have rolled the fenders and i have -3.5 degrees of camber and still, there is rubbing at full lock.

I also suspect that the TCKLine springs have settled or otherwise collapsed a little as well.

I will replace the springs with Swift Springs and I will redo the alignment. I'll re-evaluate after that.
