Hi,
The harsher ride definitely comes from the stiffer springs.
With the camber plates you should be at -1,7 degrees which is perfectly fine for a street car. You should feel the added grip in cornering. And be assured, you're not riding on the sidewall
For the track you'd want a bit more camber on the front, like -2,5. You could even go beyond -3 but then it's no longer daily driveable as it will get scary on wet streets!
Greets,
Christian
