ST185 fronts are kind of tricky. They're so short that I can't even thread a male into a female end and get down to the right length (it's close enough for my taste, but you'd have to replace them in pairs to ensure there is no pre-load on the bar). If I did that, fronts would be about $65/pair.
ST165 - since I've never had one, I don't know what the links look like in comparison to the 185/MR2. Any chance you have one you could send me?
