Not yet, just got them installed on Saturday and what a PITA. Worked on the Z with a friend for a total of 25 hours. But got a lot done. I should have it retuned in the next month or so.
I just tried uploading them and my Iphone died, but I am leaving work momentarily. I ordered them on the 17th of October and they were shipped to my door on the 18th of November. Real fast turn time, considering shipping was nearly a week. I think Getyourwheels has a few sets in stock now, which would mean a 1-2 week wait only.
I'm thinking my 245s in the front and 275s in the rear will be fine for now until I burn them up. I too want 305s in the rear and will more than likely go with hankook. They are budget friendly. But secretly I want RE11s, lol.
But I just ordered an Aerojacket SS hood in CF with good splitters so tires will be on the back burner for now. I need my wheels to show up, I already have a buyer for my stock Rays. I'd probably use that cash for some new rubber or get a jump early on the amuse replica in Cf from Aerojacket.
