Sent my OSG to TRE around the end of August, just after my 3rd track day with the Evo. I was hoping for a 2 week turnaround, but got it about a month later, just in the nick of time. I received it on 9/30, but the bolts for the arms were left behind, and needed to get them overnighted. I installed it back on 10/1 and wrapped it up on 10/3, drove it to Chicago, and flushed it for the break-in before taking it out on track. The diff felt much better overall, and the car felt like it was getting more of a push from the rear end. Have had one track day on it so far, though I think the difference will be more pronounced in autox.
