around 10k-12k maybe more. They were on the car since last june. And in the first 2 weeks I put almost 2.5k on them. Since then its been DD some spirited driving and one track event where I shared my car so it saw about 40 laps that where a minute each.

Rears where completely toasted, fronts still had some life left. If I ran less camber/castor (currently -2.4/7.5ish) they'd of laster even longer.
