You can find these on ebay for about $45 shipped iirc. Made by a company with the unimpressive and weird-sounding name of Megan Racing. So it comes with NO instructions or anything. But a quick trip under the car told us what we needed to know. Basically it bolts to each of the control arms, and to two points on either side of the frame under the firewall. The install was a pain because we didn't approach the job correctly at the beginning, but once we figured out that if you just jack up the car from under the control arm mount, everything else is a piece of cake. Took a while to figure that out though. Otherwise, got it done, and I have to go take it out right now and see if it did anything noticeable to tighten up the chassis/frame.
