what kind of lug nuts will i need?

[Jung]

yo,

im buying some 18inch flik hornets off of the site on saturday, but i realized i'd probably need new lugs. i believe they're et35, but im not sure right now.. i know that's a deciding factor on length, im still waiting on a pm back from the seller. can anyone tell me if i can use the stock lug nut seat (bowl shaped?) or if i have to get some cone shaped lugs?
thanks

im running 10mm spacers on stock rims right now, my lugs for that are i think 10 longer than stock. if i could use the stock seat lugs, if they're et35 and run with 10mm spacers i could run them right?
