The Hurst wheels were indeed the most durable after-market wheel ever built. There were only two drawbacks on the wheels. They were a bit heavy and extremely expensive. They were $69.50 each in 1965! This cost did not even include the trim rings, lug nuts, or the center caps. This greatly contributed to the rarity of the wheels today. They survived some extremely vigorous testing that most other wheels failed. George Hurst never compromised quality for any reason. They are by far the best looking (heavy duty)wheel you can put on an early (64-67) GTO. I love em !!!
