Ive noticed the ctr tach goes up to like 11 or so thousand rpms. My eg6 si tach goes to like 9 grand... Im a dork but anyway... im not a huge fan of the wall clock tachs, not in a daily driven car anyway. I was just wondering how much effort is involved. I know the type r cluster aren't exactly cheap but neither are the big tachs. Any input would be greatly appreciated. I am pretty mechanically and electrically inclined(not like a electrical engineer, but i know the basics).I work on benz's for a living so it cant be any harder than that.
