I personally bought the S281 wing because there were few around on our cars, or at least my area. I was wingless for a while but decided the rear needed just a slight touch of something and I thought it looked the best. Not too big, but just enough.
Thanks ! Its broke atm. I've been out in the garage tearing it down. Low compression on #8 and oil on #6 spark plug. It's not looking good though, I was hoping the oil was getting into #6, past an intake gasket but it looked good when I took it off. Oh well, back to work !
