I've got one of the ones from Art Rassmussen. It's definitely cleaned up the engine compartment for my car.
I went with a non-power steering unit that is still functional with the 265/40-18's I have up front. I'd tend to recommend doing power steering for most cars. Mine isn't as much fun in crowded parking lots.
What did that unit/setup cost? Is it comparable to what Steeroids has on the market in terms of quality and price? Do you feel that it has made much of an improvement over a full rebuilt stock setup to justify the $1,000 plus dollars?
