Have not had time to deal with any Z stuff. I've been modding the wife's Audi TT.
I did get yet another exhaust (#6). I went with the EVO3 Greddy exhaust. I also went from Sparco to Corbeau seats. I had to buy Planted Technologies seat brackets so that I can fit in the car with the new seats. The brackets were the same height as the Sparco brackets. Took the Corbeau seats out!! Trying Status seats next. The lower subframe brace was damaged so I replaced it. Thinking about new wheels also...Pics soon. (no ZdayZ this year for me)
