I have the opportunity to possibly buy a set of Eibach sportline springs for a very good price ($200 CAD or $146 USD) wondering if anyone can speak on how they are for street and track driving.
I’m guessing I will have to change bump stops in the rear but I’m okay with that.

These Eibach springs were on my ‘14 GT Track Pack when I purchased it. The original struts and shocks are still present and struts top mounts are still stock (no camber plates).

Ride is quite comfortable on the street. RH is way better than factory with rear about 1/4” higher than front (measured ground to fender/quarter 12 o’clock). GT Track Pack has 19x9 wheels with 255/40 tires making the diameter ~27.04 inches so keep that in mind when comparing to your wheel/tire diameter. Also the GT probably is heavier by ~100 lbs mostly on front axle.

Another consideration is that you will gain some negative camber as the springs lower the body. Toe will also change slightly gaining toe out. If you install camber plates which makes sense especially since you have the struts taken apart is then adjustable back to street settings, or easily adjusted for track events.
