Ive gotten those full suspension steering kits from ebay before for my 1990 Honda accord YEARS back and they are worth the money I would say. Came with like the full front end (control arms, inner/outer tie rods, ball joints, etc) But then again, i was also driving a 1990 honda accord and not an IS250 like i am now.
They are all refurbished parts even though the kits will say brand new. Cleaned up with a couple bolts here and there changed. It all really depends on what you are trying to get out of your replacement parts. For a quick fix OEM part on a stock car, I would do it (I actually did it). If your trying to get performance out of it, then I would look elsewhere
