Hey fellas, happy to join the forum I have been lurking for some time now, I have an e89 Z4 35is 2011 in Atacama Yellow much like a certain someone on this forum. I bought this car while I was in university and now as a young grad and I have been planning to slowly build this car up. Right now It has an intercooler, intakes and jb4 tune. Which Im planning to run a backend flash soon. Any advice and all advice is extremely welcomed!
