I have not; however, I don't believe in spacers when tracking the car. I suggest removing them for track duty.
from what it looks like, people are saying hub centric spacers are safe for track... im just worried about the quality of the bonoss ones... they seem like they're good quality but I'm just not sure if I'd be willing track them
Bonoss makes a high quality spacer, so no concerns there. Tensile strength is appropriate and they're hubcenric. So long as the bolts are the correct length (I assume they are) and they're torqued properly you should be good from a safety standpoint, if that's your concern. I remove them for different reasons.
I would have no qualms about tracking them as long as they're properly installed/torqued to spec.
There would be no issues since the thread diameter and pitch is maintained with the Bonoss spacers.
Thanks, my concern is stud length. Some of the Si/Integra folks broke their wheel locks when torqued because the spacer studs were too long.
I would first try to thread the wheel nut on the stud (without the wheel in place) and measure the depth of engagement before it bottoms out on the head.
So I noticed two Bonoss spacers for the FL5:
AL6061-T6 is more or less the industry standard for high quality automotive wheel spacers. AL7075-T6 is objectively stronger, but you begin to enter diminishing returns and it's overkill. Not necessary IMHO and it's materially more expensive.
Yes, I could see that. I suppose it doesn't hurt to go stronger. I'm not aware of the unintended consequences of going the AL7075-T6 route.
