Im currently looking into a 9" rear and need to find out what studs/lugs will work for me. I run my stock Zr1 rims on the street and would like to run pro-stars at the track. can anyone point me in the right direction for which lug nut I need to run both setups. Also should I get stock 12mm studs or 1/2 longer than stock?

The Pro-Stars take a long shank mag style lug. The shank is 1.310" long and around .687" diameter. You will probably want open end for your track wheels.

Ya im going with 1/2 longer studs. Do they make acorn style lugs open ended? if so ill just run these on my zr1`s and switch to shank style when riding pro-stars or, is there a lug nut that works for both worlds?

No there is not a lug that works for both wheels. Open end 12mm acorn style will work with your ZR1s and open end 12mm shank style will work with the Prostars.
