Its shifting at about 6k maybe just a little less, and no like a dumb ass I didnt I wasnt sure how to do them on the car or what size I wanted because I was wantin a cam over the winter but did a intercooler instead. And a lil off subject but can u do them on the car, how hard, and what size would I want? And also will that change drivability and how?(ibe honestly never looked that deep into springs sry lol) Its my dd but I take it to the track pry once or twice a month
