Also got my 18G comp cover machined to fit my wheel. Not sure what this does for classing. I just didn't want to shell out 2k plus on a t3 setup right now so this thing should cure all the flow issues that may come up with the 16G comp cover.
Thanks goodhart for sending me the groupbuy link on the carbon fiber sunroof.
