I bought the whole kit-subframe connectors, torque boxes, core support braces, shock tower braces, and cowl bracing. Pricey, but I hope it makes my car real stiff.
I was like Famous Bob when I saw how pricey they are. I picked up a set of 4 on ebay for 45 bucks shipped,guy had quit his project. They do show up on there from time to time.
