Are there 1inch wheel spacers cheaper than $150 a pair and a ?

I'm wanting some hubcentric 1inch wheel spacers to put on the rear of my 03 gt that has 17x9 fr500's. Maximum Motorsports has some but there $75 a piece. That seems way to pricy for me, in fact everything MM makes is to expensive for most people.

Another question. I have a 03 5 speed gt with wheel replica 17x9 fr500's, will I have to grind off some of my old wheel studs to get the wheel to fit?

Thanks
Josh
