Just finished mounting and balancing my 17x9 black SM10s… definitely one of the best wheels I’ve seen regarding runout (all under 0.009in laterally and radially measured at the bead seat and rim lips).
You’d be amazed at what “straight” wheels look like from some manufacturers.
I was impressed with the quality on the first set of Apex wheels I mounted last year for a friends C5 track car.
On an unrelated side note a few of the RT660s took just shy of 80psi to seat. I don’t think my new neighbors are a fan
I’ll be putting them on the car tomorrow night barring disaster. Fingers crossed no rubbing at stock ride height.
