I am trying to run my 68S in both vintage and PCA Club racing. On the PCA side, minimum weight for a 67S is listed at 2183 lbs. and 2271 lbs. for the 68S. Can someone clarify the reason for the extra 88 pounds required of my car? Prefer to run mine as a 68 but will present car as backdated 67 to save the extra weight if need be.
Good riding, Ron Shade, San Antonio, Texas
