Yeah, forget that.
My opinion about the power steering. Manual steering has a negative effect on maybe 1% of my daily driving, and the other 99% is all positive. One of the greatest things about a Miata is the feel when driving it, the shifting, steering, running through the revs, how it handles. I even like how it sounds. My mr2, corolla, corolla and miata all had manual steering, all of them had a better feel at the wheel than any other car I've ever driven. It's a simple mod that enhances the car with a very very little drawback. I'm also skinny as ****, it's not hard to deal with. Never had an issue during an autocross.
