Oops. Most recent discussion on here was about a Mustang and he just put Konis on it. That's where my brain went.

Sure, there are aftermarket bumpstops available. But, like I said, you want to get a set that are specific to your application. You CAN get generic ones from Energy and other sources, but you need to know what type, hardness and length to get things right. Better to use someone else's knowledge and/or trial-and-error experience there. (someone like Koni, or a reputable suspension tuner specific to your car)
