Review on Circuit Performance Shorty Black Bolt by Brandon Christianson

coverage is pretty good. The short stem looks really good on my 6ul rims on my Miata. When tightening, I used a 10mm wrench on the butt plate, held it in place, and gently tightened the first nut, tightening it to about 6 or 7 foot-pounds. The caps will hold up as long as you tighten the nut, not the cap. I also used Loctite 242 on the lock nut. Has been holding its breath well for a week now. Edit: I got one after a few months and then the other one started leaking. I chose 949 Racing stems this time.
