I have the same question. The guys at Road Race Engineering told me when i went there that they are working great and hold up to track abuse well.. I have been considering these as well..and wanna hear what you guys think too!!!
Why would there be anything to worry about with Buddy Club cams? A cam is a cam. Given the same lift and duration and assuming it fits your car and is manufactured from good material and with low tolerances, they should all wrk about the same. Buddy Club is a good company that makes great products.
I had never heard of buddy club prior to the aforementioned cams, and have heard countless horror stories of catastrophic engine failure from off brand cams, especially regrinds. Just thought I would see if anyone had any experience with them before I looked into buying them as I have no information about them except the specs listed from vendor sites.
