These wheels have a Street Legal status ( that text actually appears in the wheels).
On the other hand for example Summit Racing catalog states" Not for use in road,sports,solo or autocross racing".
I think these wheels are best suited for dragracing.I already did replace my rear ones 2 years ago since they had gone out of straigness( realized this in wheel balancing machine, both wheel wobbled sideways by max 1/4". I am still using those replaced wheels though, with my 26 x 15 ET Streets.They work ok at the strip without any vibration.
