As one who builds all these problem for all of the above mentioned classes (even karts,) I will have to be on the other side of this one.. I love some of the new stuff that all of the guys are doing.. I was the one that brought Rick Ferkel's #0 to Syracuse in the early 80's with the wheel covers,sideskirts and a few other Kenny Weld type items.. So I truly love the aero look.. But some of the old stuff still looks great and I don't have a problem living with it.
