Hello, I recently got some wheels from a friend and they are an 8 lug bolt pattern, unfortunately my car is a 5 lug does anyone know where I can get wheel spacers that can convert it?

I suspect what you have is a wheel with 2 different 4-bolt patterns. 8-lug wheels are only used on 3/4 ton and up trucks. 

I have a 999 subar with a 5 lug pattern. He's wheels I have, have 8 lug holes, so I need a 5-4 or 5-6 or 5-8 lug conversion

Doesn't exist. GL

What doesn't exsist?

You wont find a converter to go from 5 to 8 lug wheels. If it is one of those "universal" 4 lug rims it will have 2 sets of 4 lug holes and will likely fit on a 4x100 then you could find adapters to fit.

 

Usually far easier to just find a good set of the correct size for the car though. For the cost of the spacers you can find a good set of Subaru rims and tires. A few chryslers and VWs and GM cars also run the 5x100 pattern. Rims on my old impreza were off a chrysler sebring. Chevy cavalier, pontiac sunfire, dodge neon all run it.
