Question what lug bolt length would i need to run to mount 15x8 et0's ? ive searched but i cant find any clear answers

 

Its not a point of bolt length, as the mounting face of the wheel isn't increased of width...

However, you'll want to recheck your fitment; as 8" wide wheel at a 0mm et will SURELY poke past the fender... a lot past.

its just temporary but i just need bolts with smaller heads? i dont want to do the stud conversion cause its more money and this setup is temporary can you show me exactly what screws to get?

 

You're not going to have an issue with bolt size like the fox just pointed out. With such a low offset wheel the outside face of the wheel is going to be positioned way outside the wheel arch. it will look like an exaggerated hot wheels low-rider. If that's what you want fine, but if this is a daily driver I wouldn't venture down this path.
