you can easily get 5000 miles out of a set of Victoracers on the street, which are quite a bit softer than the A032Rs. That's my reference. Also there was a 93 RX-7 R1 that used to do track days and autocrosses up here that ran them as daily drivers. He got about a year out of them. 8000-10000 miles would be my guess, again....depending on what kind of events you might do, alignment, size to weight ratio...etc.
