Apologies up front for the very generalized thread title, but I'm really just hoping for a round about answer (general approximate).
The general scenario question is what would an approximate lap time difference be for an FE running brand new slicks vs very used slicks (10+ heat cycles / 1yr old), on a track between 2-2.5 miles long with 14 or more turns?
If you have anything relevant to share, even substituting variables from the above scenario (i.e. FM instead of FE), I'd appreciate it.
This really is mostly just a curiousity question, as I am only able to do track days with my FE for now and have been using used tires while I learn the car.
Thanks,
Mike
